Dutch textile company ByBorre and its founder, fashion designer Borre Akkersdijk, have created the BB.suit — a wearable Wi-Fi hotspot with GPS, a music library, and an air purifier.
Version 1.0 of the suit, which has electrical threads woven into the fabric, was showcased at the SXSW music and film tradeshow in March, where a model’s location was shown on Google Maps, allowing anyone to locate the suit using its GPS data, and then upload songs to a 22Tracks platform.
Version 2.0 introduces an additional tech — an air purification system. Demonstrated at Beijing Design Week in September, the garment purifies the polluted air surrounding the wearer. According to Dezeen, designers Akkersdijk and Eva de Laat collaborated with Martijn ten Bhomer from the Eindhoven University of Technology, Daan Spangenberg Graphics, and StudioFriso to create the one-piece suit, which looks like an adult onesie.
“The BB.Suit started because everyone was talking about wearable technology, the bracelets, the glasses,” Akkersdijk told Dezeen. “We thought about how we could really integrate the electrical threads and sensors and not just stick them on.”
The electrical yarns are woven into the body and legs of the outfit, while the long sleeves and a hood are made from standard textiles. The air-quality sensor at chest level is connected to a hidden platform chip that tracks and transmits data counting the particles of carbon monoxide, methane and dust around the body. The chip is wired to a battery and a cold plasma node on the back of the suit.
You won’t be able to outfit yourself with the garment yet, as it was created as a step towards a connected wearable platform rather than a product to be marketed.

As location penetrates smaller and smaller devices that lack memory and computation power, GNSS chips must reacquire the standalone capability that they shed when first going to small form factors such as phones. A new chip with a new architecture demonstrates navigation and tracking and avoids burdening its main processor with heavy software.

End users first experienced the amazing capabilities of GPS 12 years ago with early mass-market GPS devices. The focus was on navigation applications with specific tracking devices like personal navigation devices and personal digital assistants (PNDs, PDAs). With the advent of smartphones, GPS became a must-have feature. Other constellations were added to improve performance: GLONASS, QZSS, SBAS, and very recently, BeiDou. In the current phase, the focus is shifting to fitness applications and background location. This is not an insignificant change.
Always-on connected applications, high-resolution displays, and other such features do not improve battery life. This article describes new ultra-low-power, high-accuracy location solutions for wearables’ power consumption.
Impact of Always-On Connected Applications
New applications require frequent GNSS updates with regard to user position. Sometimes the application will be open and other times it will not. The chips need to keep working in the background, buffering information and taking predefined actions. The GNSS chips need to be able to cope with these new requirements in a smart way, so that battery life is not impacted. Saving power is now the name of the game.
Furthermore, GNSS is penetrating small devices: the Internet of Things (IoT) and wearables. They do not have the luxury of large resources (memory, computation power) as smartphones do. GNSS chips cannot leverage the resources in those devices; they need to be as standalone as possible. In summary, the new scenario demands chips that:
do not load device’s main processor with heavy software;
use less power while maintaining accuracy;
can be flexibly configured for non-navigation applications.
New GNSS Chip Architectures
The industry is designing chips to meet these requirements by including the following features:
measurement engine (ME) and positioning engine (PE) hosted on the chip;
accelerometer and other sensors directly managed by the chip;
new flexible configurations, duty cycling intervals, GNSS measurement intervals, batching, and so on.
These features require hardware and software architectural changes. The new chips need more RAM than that required for smartphones, as they must now host the ME and PE. Wearables and IoT devices are small, cheap, and power-efficient. They do not have large processors and spare memory to run large software drivers for the GNSS chip. In many cases, the device’s microcontroller unit (MCU) is designed to go into sleep mode if not required, that is, during background applications. Therefore, new GNSS chips with more RAM are much better adapted to this new scenario.
New chips must tightly integrate with sensors. The accelerometer provides extremely valuable information for the position update. It can detect motion, steps, motion patterns, gestures, and more. However, as a general rule, the MCU’s involvement in positioning should be minimized to reduce power consumption. For power efficiency, the new GNSS chips must interface directly with the sensors and host the sensor drivers and the sensor software.
Finally, new chips must adapt to different human activities as they are integrated into wearable devices. This is the opposite approach from past developments where GNSS development was focused on one use case: car navigation. Now they must adapt to walking, running, cycling, trekking, swimming, and so on. All these activities have their particularities that can determine different modes in which new GNSS chips can work. Electronics must now conform to humans instead of the other way around. New wearable-chip GNSS tracking strategies include dynamic duty cycling and buffering, which contribute to the goal of reducing power consumption without compromising accuracy.
Satellite positioning embedded in devices over the last few years first saw on-chip positioning before the era of smartphones, where you had dedicated SoCs that supported the silicon used to compute the GNSS fix. These expensive chips had lots of processing power and lots of memory. Once GNSS started to be integrated into cellphones, these expensive chips did not make sense. GNSS processing could be offloaded from the expensive SoCs, and part of the GNSS processing was moved onto the smartphone application processor directly.
Since navigation is a foreground type of application, the host-based model was, and is still, a very good fit. But with advances in wearable devices, on-chip positioning will become the new architecture. This is because the host processor is small with very limited resources on wearables; and because energy must be minimized in wearables, reducing the processor involvement when computing GNSS fixes is critical.
Some vendors are taking old stand-alone chips designed for PNDs and repurposing them for wearable devices. This approach is not efficient, as these chips are large, expensive, and use a lot of power.
GNSS Accuracy
While the new fitness and background applications in wearables have forced changes in GNSS chips’ hardware and software architectures, GNSS accuracy cannot be compromised. Customers are used to the accuracy of GNSS; there’s no going backwards in performance in exchange for lower power consumption.
Figure 1. Software architecture for wearables.
A series of tests shown here demonstrate how a new wearable, ultra-low-power GNSS chip produces a comparable GNSS track to existing devices using repurposed full-power sportwatch chips, while using only a fraction of the power.
Speed Accuracy. Not only does the ultra-low-power solution produce a comparable GNSS track, it actually outperforms existing solutions when it comes to speed and distance, thanks to close integration with sensors and dynamic power saving features (Figures 2 and 3).
Figure 2. Ultra-low-power versus full power.Figure 3. Full-power sportwatch, left, and ultra-low power chip, right, in more accuracy testing.
GNSS Reacquisition. GNSS-only wearable devices face a design challenge: to provide complete coverage and to avoid outliers. This is seen most clearly when the user runs or walks under an overpass (Figure 4). Familiar to urban joggers everywhere, the underpass allows the user to cross a busy road without needing to check for traffic, but requires the GNSS to reacquire the signals on the tunnel exit. See the GNSS track in Figure 5: when the device reacquires the signals, the position and speed accuracy suffers.
Figure 4. Position accuracy on reacquisition, emerging from overpass.Figure 5. GNSS speed accuracy on reacquisition.
Using the filtered GNSS and sensors, however (Figure 6), enables smooth tracking of speed and distance through the disturbance.
Figure 6. Sensors provide smooth speed estimate.
Urban Multipath. The pace analysis in Figure 7 shows a user instructed to run at a constant 8-minute/mile pace, stopping to cross the street where necessary. The red line on each plot shows the true pace profile. The commercial GNSS-only sportwatch on top shows frequent multipath artifacts, missing some of the stops and, worse for a runner, incorrectly showing erroneously high pace. The ultra-low-power chip captures all the stops and shows a constant running pace when not stopped.
Figure 7. Urban multipath tests.
It is well known in the community that regular sportwatches give unreliable speed and distance estimates in urban environments — where most organized running races are held! There’s nothing worse, as a runner, than to hear the distance beep from your watch going off earlier than expected: how demoralizing! The major benefit of this solution is that the speed estimate is much more reliable in the presence of multipath. At the same time, battery life can be extended because the GNSS is configured to use significantly less power.
fSpeed in existing solutions is computed in two different ways: indirectly from two consecutive, time-stamped GNSS position estimates, each derived from range measurements to the satellites, and directly from the Doppler frequency offset measurements to the satellites. Both range and frequency measurements are subject to significant error when the direct path to the satellite is blocked and a reflection is acquired.
The effects of multipath mean that the range error may in typical urban environments be hundreds of meters. The frequency error is also a function of the local geometry and is typically constrained by the magnitude of the user’s horizontal speed.
In either case, the GNSS device alone, in the presence of signal multipath, generates a velocity vector that fluctuates significantly, especially when there is a change in the satellites used or signal propagation path between the two consecutive positions. A variety of real-life cases generate this sudden fluctuation in velocity vector:
Running along a street in an urban canyon and turning a 90-degree corner.
Running along a pedestrian lane and taking a short road underpass.
Running under tree cover and suddenly arriving at an open area.
Running under an elevated highway and turning 90 degrees to a wide-open area.
In each case, the chips are using a certain set of satellites, and suddenly other, higher signal-strength satellites become available. A typical situation is for the position to be lagging the true position (while under tree cover, going through an underpass) and needing to catch up with the true position when arriving to the wide-open area. A jump in position is inevitable in that situation. This is not too bad for the GNSS track, but it will mean a noticeable peak in the speed values that is not accurate. Fitness applications save all of the computed speed values and generate a report for each workout. These reports are not accurate, especially the maximum speed values, for the reasons explained above.
Figure 8 describes a typical situation where the actual speed of the runner is approximately constant. GNSS fixes are computed regularly; however, the speed computed from subsequent GNSS fixes have sudden peaks that spoil the workout speed reports.
Figure 8. Sudden peaks spoil workout speed reports.
The new ultra-low-power solutions for wearables solve this problem by deriving speed and accumulated distance from the sensors running in the device. This avoids incorrect speed peaks, while still being responsive to true pace changes by the runner.
In running biomechanics, runners increase pace by increasing step cadence and/or increasing step length. Both methods depend on the runner’s training condition, technique, biomechanics, and so on. As a general rule, both step cadence and step length increase as the running speed increases from a jogging speed to a 1,500-meter race speed.
A runner may use one mechanism more than the other, depending on the moment or on the slope (uphill or downhill). In the case of male runners, the ratio of step length to height at a jogging speed is ~60 percent.The ratio of step length to height in a 1,500 meter race speed is ~100 percent. For female runners, the respective ratios are ~55 percent and ~90 percent.
The ultra-low-power chips take into account both mechanisms to derive the speed values. The sensor algorithms count the number of steps every time interval and translates the number of steps into distance multiplying by the step length. The reaction time of the GNSS chip to speed changes based on a higher cadence is immediate.
Speed changes due to longer steps are also measured by the ultra-low-power chips. The step length is constantly calibrated by the GNSS fixes when the estimated GNSS position error is low. The reaction time of the GNSS chip to speed changes based on longer steps has some delay, as it depends on the estimated error of the GNSS fixes.
Manufacturer
The ultra-low-power, high-accuracy, 40-nanometer single-die BCM4771 chip was designed by Broadcom Corporation. It is now being manufactured in production volumes and is focused on the wearables and IoT markets.It consumes five times less power than conventional GNSS chips (~10 mW) and needs 30 KBytes of memory in the MCU for the software driver. It features tight integration with the accelerometer and innovative GNSS tracking techniques for extremely accurate speed, accumulated distance, and GNSS tracking data.

A new Placecast poll indicates that nearly 118 million smartphone owners will be relying on their phones for holiday shopping this year. For smartphone owners who plan to do holiday shopping, three out of four will use their phones to find sales, comparison shop, take pictures of possible gifts, and make purchases.
The survey also showed that American shoppers are very aware of in-store beacons, despite the fact that it is a relatively new technology; more than half (52 percent) of the cell phone/smartphone owners surveyed said they have heard of in-store beacons, and 15 percent have engaged with them.
“Brands that embrace beacons are highly likely to see a spike in their sales in the coming shopping season and in general,” said Placecast CEO Alistair Goodman.
Beacon technology is only one indoor location technology being pursued by retailers. Kevin Dennehy’s Wireless LBS Insider column from August, Indoor Location Has Major Growing Pains, but Big Upside, provides an overview.
Conducted in October among more than 2,000 U.S. adults, this was the fifth survey in Placecast’s Alert Shopper series, one of the longest running research series around how consumers interact with various marketing and purchasing mechanisms. This year’s poll reveals the latest trends in mobile shopping and provides key insights for brands and technology providers on how to connect with the highly connected consumer this holiday season, when stakes are high. The poll was conducted online within the U.S. for Placecast by Harris Poll.
According to the National Retail Federation (NRF), holiday spending will be up nearly 5 percent this year compared to last year, with the average person expected to spend about $800. The NRF reports that gift givers “plan to splurge” for holidays like Christmas, Kwanzaa, and Hanukah: “Consumers are spending more across the board on family, friends, co-workers, pets and even babysitters…Sales and discounts were listed as the most important factor.”
“It’s not surprising that consumers are most influenced by sales and discounts; the question is, what is the best way to get these offers to them? Our survey looked at various ways brand can reach customers, and we found that reaching users on mobile while they are near stores, and using in-store technology — like beacons — are some of the best ways of reaching consumers who are looking for offers, or for more information to make a purchase,” said Goodman.
Beacons are a small, low-cost piece of hardware installed in stores. They emit a signal (called Bluetooth low energy, or BLE) that can be targeted directly to phones. Beacons can bring the analytics and targeting capabilities of the online experience to physical stores — for example, sending a discount for perfume to a 40-year-old woman who has recently done an online search for scents.
Because beacon technology is relatively new, the high awareness level discovered in this wave of the Alert Shopper series may seem surprising to the industry; the research team involved in data analysis for the Harris Nielsen poll explains the possible cause: “Consumers are clearly voting in favor of beacons due to stores promoting them and the value they deliver in couponing. While awareness seems high at 52 percent, this may be due to people wanting to identify with the coolness of new technologies, and certainly indicates huge promise for it. Minority Report is looking more and more like a reality than a movie,” said Kathryn Koegel, chief of Insights and Communications Steampunkt Collaborative.
Goodman seconds this “halo effect” of new tech: “There could very well be a huge halo effect here, but nonetheless, one fact remains: we are all now assuming that there is technology in stores that can connect with our phones — whether it’s opening an app or getting a push notification. But the real art lies in delivering timely and useful ads and offers, not overwhelming the consumer, and making sure the promotions are targeted accurately.”
The Alert Shopper V survey revealed that 15 percent of cell phone/smartphone owners had interacted with beacons. “Though this number is likely higher than the actual number of people who have interacted with in-store beacons, the fact that people are highly aware of them and think they interact with them bodes well for the technology,” said Koegel.
The importance of in-store marketing was underscored by another data point from the Placecast survey; the top activity for Mobile Millennial females (women 18-34 who own a smartphone and plan on doing any holiday shopping this year) — when asked what they plan to use their smartphone for while holiday shopping this season — is searching for a coupon for a store they are already in, with over half (52 percent) looking to save money by checking their phones. The same percentage said they would use their smartphone to take a picture of a potential gift to text a friend or family member for their opinion (52 percent).
The Alert Shopper Survey #5 revealed these key takeaways for brands and marketers this holiday season:
Phones are an integral part of the shopping process: among those who plan on doing any holiday shopping, 3 out of 4 smartphone owners plan to use their phones for some part of their gift-finding and buying experience.
Among all smartphone owners, searching for an item in a search engine to find a local retailer topped the list of mobile actions for holiday shopping this season, with 2 out of 5 (39 percent) saying they plan to use their smartphone for this; sending a picture of a potential gift to a friend or family member at a close second (38 percent), followed by searching for a coupon for the store they’re in (33 percent).
Mobile Millennials are the most active mobile shoppers this holiday season: Young men ages 18-34 (91 percent) and women ages 18-34 (85 percent) who own smartphones reported the highest percentages when asked if they plan to use their phones while shopping this holiday season; these Millennials make up about 25 percent of the United States population, outpacing Baby Boomers and Gen X (ages 28-38). Though they have not reached their peak spending potential, Millennials nonetheless control 21 percent of consumer discretionary purchases, which is estimated at over a trillion dollars in direct buying power and a huge influence on purchases by older generations (i.e., parents and grandparents).
Moms and dads with children under 18 in their household will be very active on mobile: 86 percent of dads plan to use their smartphones for holiday shopping this year. When asked what they will use their phones for the most popular answer among dads was “use my phone to look for an item in a search engine to find a local retailer.” Over half (54 percent) gave this answer. Three out of four (75 percent) mothers plan on using their smartphones for holiday shopping this year. While men are searching for retail locations, mobile moms selected “take pictures of potential gifts to text and get opinions from friends/family” as the top mobile activity, with nearly half (48 percent) saying they will do this.
Nearly 5 million smart and basic wearable bands shipped in Q3 2014, with total unit shipments increasing 37% quarter on quarter as Android Wear made its mark for the first time, according to a report by independent analyst company Canalys.
Motorola Mobility’s Moto 360 was by far the most successful of the initial Android Wear devices, accounting for more than 15% of the smart band market according to Canalys estimates. Despite being supply-constrained, its appealing design helped it to easily out-ship other Android Wear products.
LG has responded to early interest in the Moto 360 by quickly adopting a circular display with the G Watch R.
Meanwhile, Samsung remained the overall smart band market leader, and the company has already begun to experiment with larger display sizes and cellular connectivity with the Gear S, its sixth smart band.
Though the platform is still young, Android Wear will be fundamental to the development of the market, as it is poised to be one of the two dominant wearable operating systems outside of China, alongside Apple’s Watch OS. But Google will need to redesign the Android Wear user interface before the platform can achieve its true potential.
‘The announcement of the Apple Watch late in the quarter has likely had an effect on sales of existing devices, as some consumers will choose to wait for Apple’s wearable,’ said Canalys Analyst Daniel Matte. ‘The smart band market was flat between Q2 and Q3, but with an installed base of over 1.8 billion Android smart phones, there is a huge potential market of Android users not considering an Apple Watch.”
Fitbit and Jawbone held onto their first and second place positions, respectively, in the basic band market for the quarter, and both have just announced new products. Garmin passed Nike to take third place in shipments, while Xiaomi and Huawei also overtook the one-time market leader and rounded out the top five. “Low-end basic bands providing simple activity tracking functionality are becoming increasingly commoditized, and will flood the market heading into the holidays, especially in China,” said Canalys Analyst Jingwen Wang. ‘To combat this, Fitbit, Jawbone and others have attempted to make basic bands smarter, adding various smart watch features and increasing the sophistication and integration of sensors.’
Google Fit, Microsoft Health and the Samsung Digital Health Platform have all recently been announced in response to Apple’s HealthKit. While the new Microsoft Band does not have strong hardware appeal, Microsoft’s cross-platform cloud services approach is a wise strategy, and the company is importantly staking its relevance early in a new market. There is tremendous opportunity for brand new services on wearable platforms, and not just in the area of health and fitness. Expect developers to eagerly embrace Apple’s WatchKit SDK, expected to be released in early 2015.
Wearable band shipment data is taken from Canalys’ Wearable Technology Analysis service, which provides quarterly market tracking, including country-level estimates. Canalys defines basic wearable bands as devices serving a specific set of purposes that act as accessories to smart devices, are designed to be worn on the body and not carried, and that cannot run third-party computing applications. Smart wearable bands are multi-purpose devices that serve as accessories to smart devices, are designed to be worn on the body and not carried, and are capable of running third-party computing applications. Bands are wearables designed to be wrapped around the body and do not include activity trackers in the form of clips.
CSR plc today announced the launch of its SiRFusion Software Development Kit (SDK) for Android application developers. The solution enables indoor positioning for Android developers looking to create next-generation apps.
Developers can now leverage the SiRFusion library to rapidly integrate new location-based capabilities and services such as indoor location tagging and analytics for social networking applications, indoor navigation, lone worker efficiency and safety capabilities, as well as indoor asset tracking and targeted e-commerce services.
CSR is being acquired by Qualcomm, with the transaction expected to close by the end of the summer of 2015.
Mobile applications with integrated SiRFusion can now deliver the ubiquity of outdoor navigation to indoor environments without costly surveys or infrastructure upgrades. SiRFusion combines real-time Wi-Fi signals, satellite positioning information, pedestrian dead reckoning, and the company’s cloud-based CSR Positioning Center to calculate accurate indoor location. SiRFusion technology provides the accurate indoor position fixes needed to make continuous indoor navigation a part of everyday life. The system automatically crowd-sources a venue’s indoor Wi-Fi signatures as consumers walk through the location, and it has also been architected to accommodate future proximity and location technologies such as Bluetooth Smart beacons, Wi-Fi Round Trip Time (RTT), and Indoor Messaging System (IMES).
“Offering indoor positioning accurate enough to be useful has been a challenge that the industry has been trying to solve for many years,” said Anthony Murray, Senior Vice President, Business Group at CSR. “But with consumers coming to expect anytime-anywhere positioning wherever they are, our customers have continued to express a growing interest for accurate indoor positioning without the need for additional infrastructure. With our SiRFusion Software Development Kit, we have, for the first time, made indoor location a reality for developers who want to deliver innovative location-based products and services without proprietary infrastructure.”
SiRFusion for Android can be integrated into any app running on Android version 4.4 or later. The SDK will be available for download from www.csr.com in Q1 2015, and will include the SiRFusion library, API descriptions, and a Developer’s Guide. CSR will demonstrate SiRFusion for Android at the Location and Context World conference December 2-3, held at the JW Marriott in San Francisco, and at Consumer Electronics Show (CES) in Las Vegas January 6-9, 2015.

Location-based services company Telenav has announced new capabilities and updates to its free Scout mobile application that make the process of connecting and getting together easy and fun. Scout users can now manage the details of creating an event, contacting and inviting friends, choosing a location, communicating with the group and navigating, all within the updated Scout application. Scout is powered by OpenStreetMap.
For iOS devices, the new app experience will offer predictive, intuitive traffic push notifications for users’ everyday trips, eliminating the need to manually check for traffic delays. The newest version of Scout is now available from Google Play for Android and iTunes for iOS.
The results of a new survey from Telenav underscore the common pain points of planning events, meet-ups and meetings for consumers — especially Millennials — which Telenav is aiming to help alleviate with the updated Scout app. Nearly half (49 percent) of Millennials reported that they would find it useful to have a single solution that enables them to plan an event, communicate with attendees while they’re en route, and see each other’s estimated time of arrival.
“Mobile users have come to expect more out of their navigation devices and applications,” said Rohan Chandran, president and general manager of Telenav’s mobile division. “Navigation alone is critical, but it is a commoditized utility. We are looking to embrace the things that people really care about — the experiences in real life for which you navigate. Getting together should not be hard work, and we are trying to solve that. Scout is the new way people connect, get together, and go places in real life. It’s the only app that takes you all the way from chatting, to making event plans, to getting together in person, complete with voice-guided GPS along the way and everyone’s whereabouts and ETA pinpointed on the map.”
Scout’s new in-application features include:
Socialized Navigation Experience. In addition to offering invitees voice-guided, turn-by-turn directions to the event destination, Scout offers real-time location and ETA insights so guests are able to view the positioning of other guests on the navigation map. This prevents a barrage of “Where are you?” texts and calls while en route — and eliminates questions about where directionally challenged or perpetually tardy friends are.
Easier Meet-Up Invitations. Scout replaces what typically requires multiple applications by conveniently taking care of all the details of getting together, from inviting guests on their contact lists, to picking a day, time and location. “Did I get an invite?” and “what time is the event taking place?” are the last questions that organizers will be asked.
Group Chat. For the friend who is always left out, Scout users can now chat with all of the other event attendees directly within the app, allowing them to avoid juggling multiple text and phone conversations, and easily adjust and discuss the details of an event.
Predictive, Personalized Traffic Reports (iOS Devices Only). Users can schedule traffic report updates informing them of road conditions for their regular drives, and recommended alternate routes.
OriginGPS has launched the Nano Spider, a tiny yet fully integrated GPS receiver. The Nano Spider module is designed to support ultra-compact applications where size is at a premium, such as smart watches, wearable devices, trackers and digital cameras.
OriginGPS, which previously introduced the Micro Spider (5.6 x 5.6 mm) module, said the Nano Spider is 47 percent smaller than its previous solutions, measuring 4 x 4 x 2.1 mm. The Nano Spider’s proprietary structure is a multi-level circuit for surface mounting, built to reduce footprint size.
“The wearable technology trend requires components that balance a small size with high-performance and best-in-class power consumption,” said Gal Jacobi, CEO of OriginGPS. “OriginGPS aims to continue to shrink the size of components, while increasing features to make adding location functionality possible for every device.”
OriginGPS’ Nano Spider continuously tracks all GPS satellites in view and provides real-time positioning data in the standard industry format defined by the U.S. National Marine Electronics Association (NMEA). The Nano Spider offers a complete System in Package (SiP) that includes:
Fully integrated features – The Nano Spider includes a low noise amplifier (LNA), surface acoustic wave (SAW) filter, temperature controlled crystal oscillator (TCXO) and real-time clock (RTC) crystal, a power management unit, and radio frequency (RF) shielding.
Superior sensitivity and performance – The Nano Spider module offers accuracy of approximately one meter, and achieves a rapid time to first fix of less than one second and tracking sensitivity of -163 dBm.
Continuous connectivity with minimal power consumption – It achieves a state of near continuous availability by detecting changes in context, temperature and satellite signals by maintaining and opportunistically updating its internal fine time, frequency, and satellite data, while consuming microwatts of battery power.
Improving marginal signal conditions – It includes OriginGPS’ proprietary Noise Free Zone (NFZ) system to increase noise immunity even under marginal signal conditions, such as urban canyons, under dense foliage or a rapidly changing receiver position.

Swiss-based u‑blox has introduced the EVA‑M8M stand-alone positioning module. The EVA-M8M GNSS module brings concurrent multi-GNSS performance into the ultra-compact EVA footprint.
Designed for cost- and space-sensitive applications, the highly integrated 7 x 7 x 1.1 mm LGA module comprises all necessary components, including crystal and passives. EVA-M8M only requires an external antenna to provide an accurate position without the need for host integration. Components have been selected for reliable operation in the field over the full operating temperature range. The module is also compatible with the EVA-7M GPS module, allowing for easy upgrading of existing designs at minimal cost, u-blox said.
The module supports GPS, GLONASS, BeiDou, QZSS, and SBAS augmentation systems. Based on u‑blox M8 performance, the module achieves -164 dBm tracking sensitivity, fast acquisition time and low power consumption. EVA-M8M can track any two GNSS systems simultaneously and output a GNSS position up to 18 Hz.
“The EVA-M8M sets a new industry benchmark for compact, stand-alone global positioning performance. The module has been designed for the absolute lowest eBOM costs and ease-of-manufacturing. It is a perfect solution for cost-sensitive industrial and wearable devices,” said Thomas Nigg, vice president of product strategy at u-blox.
A UART, USB, SPI and I2C interface provide flexible connections to a host processor. EVA-M8M can also communicate directly with u‑blox’ SARA 2G, LISA 3G and TOBY 4G cellular modules to support advanced tracking and location-aware products.
Detailed information about the EVA-M8M can be found on the u-blox website. Samples are available now. For existing designs using a NEO module, the C88-M8M adaptor board can be used for easy evaluation of the EVA-M8M in existing NEO-xM designs.

Janam Technologies LLC, a provider of rugged mobile computers that scan barcodes and communicate wirelessly, has launched XT1, a powerful rugged tablet for the mobile workforce. The XT1 rugged mini-tablet is Janam’s first device to support the Android operating system, and is built to meet the diverse needs and demanding requirements of enterprise and government customers.
The XT1 combines best-in-class technologies with a sleek and rugged form factor, providing mobile workers with the information they need to make better informed decisions, increase customer satisfaction, and improve operational efficiencies, the company said. Equipped with integrated 2D barcode scanning technology to eliminate the challenges often associated with camera scanners or bulky sled attachments, the XT1 is designed to improve worker productivity in field sales, field service, healthcare, hospitality and retail markets.
“Many enterprise customers require more screen viewability than traditional PDAs or handheld computers offer, yet full-display rugged tablets are large, thick, heavy and unwieldy,” said Harry B. Lerner, CEO of Janam. “Janam resolves this dilemma. The XT1 blends cutting-edge technologies most often found in consumer phones with mission-critical key features that enterprises need such as ruggedness, sealing, barcode scanning and rapid battery recharging, among others. The result is a sleek, lightweight, rugged mini-tablet that delivers superior performance without sacrificing usability.”
In addition to 4G-ready UMTS/HSDPA/HSUPA/GSM wireless wide-area network communication, the XT1 is equipped with 802.11a/b/g/n dual-band WLAN for access to the information mobile workers need to get the job done, inside and outside the four walls.

According to a new research report from the analyst firm Berg Insight, global shipments of personal navigation devices (PNDs) declined from 28 million units in 2012 to 22 million units in 2013. There are signs that the decline is slowing and some emerging markets still experience growth.
However, on the whole, the PND market is set for a continued downturn on a global basis. Berg Insight forecasts that PND shipments will decline to only 10 million units worldwide in 2019.
A number of developments are affecting the PND market. Retailers have reduced shelf space and marketing for PNDs in favor of other consumer electronics products. Competition from other navigation solutions, especially navigation apps, is also intensifying.
Over time, PNDs will also face further competition from in-dash navigation systems as more car brands launch low-cost systems. Moreover, the installed base of PNDs is already high, and replacement cycles are likely to be prolonged since PNDs have matured considerably and many devices are now sold with lifetime map updates, giving users less reason to replace their existing devices as frequently.
The user experience for handset-based navigation apps is now improving through better integration in the car. Some vendors have released NFC-enabled car mounts enabling the owner to configure the handset to turn on the GPS and launch a navigation app when the phone is placed in the mount. A majority of car manufacturers have also started to offer smartphone integration solutions that connect the vehicle’s infotainment system with the user’s smartphone via Bluetooth, Wi-Fi, USB or HDMI. It is then possible to display and control smartphone apps using the touchscreen and controls in the car.
Higher smartphone adoption along with broader availability of low-cost and free navigation apps are important factors for the continued increase in usage of mobile navigation services worldwide. “The number of mobile subscribers worldwide using a turn-by-turn navigation app on their handset at least once per month grew from 150 million in 2012 to 180 million in 2013,” said André Malm, senior analyst, Berg Insight. He adds that in most markets, smartphones from major vendors now come bundled with free navigation apps.
The leading navigation service providers on a global basis include Google, Apple, Telenav, Appello Systems, Nokia and Garmin. Examples of major local players include AutoNavi and Careland in China, SK Planet in South Korea, NAVITIME and ZENRIN in Japan, as well as Navitel and Yandex in Russia.
Despite increasing competition from free navigation apps, many mobile operators are still marketing their own navigation services developed by companies such as Telenav, TeleCommunication Systems and Appello Systems. “App developers and operators are now trying to monetize navigation apps by introducing premium features and advertising,” said Malm. “Developers are also forced to reduce costs as competition increases, for instance by adopting OpenStreetMap data to reduce map licensing fees.”
Unicore Communications, Inc., is showcasing two new products at ION GNSS+, being held September 10-12 in Tampa, Florida.
The UM220-INS is a BeiDou/GPS+MEMS dual-system inertial navigation module for in-dash automotive navigation and high-end navigation. Besides dual-system (BeiDou+GPS) GNSS navigation, the UM220-INS features a built in six-axis MEMS and can output a GNSS+MEMS inertial positioning result, making it suitable for applications requiring high accuracy, high reliability, and high continuity positioning.
The second product is the UB280, a BeiDou/GPS dual-system dual-antenna high-precision heading board for precise RTK position and heading. According to Unicore, UB280 is based on Unicore’s mature BeiDou compatible multi-system GNSS system-on-chip (SoC), features low-power design and dual-antenna input, can offer millimeter-level carrier phase observation value and centimeter-level RTK positioning accuracy, and supports multi-path mitigation. Its advanced technology of instant and long-distance RTK is designed for high-precision positioning, navigation, and heading applications in static and dynamic environments.
Features of the UM220-INS include:
Built-in six-axis MEMS. UM220-INS has a built-in MEMS with a 3-axis gyroscope and a 3-axis accelerometer. The solution fusing GNSS and inertial MEMS enables car-navigation devices to provide a continuous and stable position under complicated environments such as basement parking and tunnels, regardless of satellite visibility.
High-Sensitivity Design. With Unicore’s Ultra-Sense high-sensitivity design, UM220-INS can provide excellent acquisition and tracking sensitivity under weak signal conditions, maintaining the position continuity and reliability of the receiver.
High-Integrated Design. Different from traditional GPS navigation products, built-in MEMS devices support the odometer / speed pulse, the reversing signal input, and more integrated, simplified overall unit manufacturers’ design.
DGNSS and AGNSS Supprt. UM220-INS has extended support for differential GNSS and assisted GNSS positioning functions, and supports RTCM2.3/3.0.
Backward Compatibility with UM220. The UM220-III N module is backward-compatible with the UM220 in size and interface, which makes upgrades easy.
