Global GNSS, a subsidiary of Polosoft Technologies, has launched a new mobile application named GNSS Surveyor, which is designed for the geospatial industry.
The application GNSS Surveyor provides location information and quality position data in real-time with sub-meter to centimeter accuracy. It needs to be connected to any external GNSS receiver via Bluetooth.
Features of the application include:
A one-touch configured command to communicate directly with the GNSS Bluetooth device.
Location information and quality of the position data in real-time with centimeter accuracy.
GPS data such as position, height, satellites and velocity.
Constellation information for GPS, GLONASS, Galileo, BeiDou, QZSS and SBAS satellites in the orbit.
Direct IP feature for RTK corrections data.
DMS to DD conversion or vice versa.
Real-time kinematic (RTK) correction data can be forwarded to a high-accuracy external device. The internal NTRIP client loads the RTCM data from the internet.
With GNSS Surveyor, location information is collected as latitude and longitude, altitude, speed or pace, bearing and UTC time.
GNSS precision includes global coverage, centimeter-level accuracy, fast time to first fix, multi-constellation and multi-band, and highest security, the company said.
Navigation uses include ground robotics navigation, lane-level navigation, heavy machine navigation, industrial navigation and tracking and commercial UAV.
Allystar Technology Co. Ltd. has launched a multi-band, multi-GNSS system on chip, the HD8040 series, to help portable devices save size and weight. The HD8040 offered in wafer-level chip-scale packaging (WLCSP).
The HD8040 series of chipsets fully supports all civil signals on the L5 band, said Shi Xian Yang, Allystar high-precision product manager at Allystar. Besides GPS, other constellations with L1/L5 signals include Galileo, BeiDou, the Indian NavIC system and Japanese QZSS.
Besides L1 band, HD8040D supports L5/B2a/E5a signals, which are expected to have lower noise and be better in multipath mitigation mainly due to the higher chipping rate of L5 signals relative to L1 C/A code.
HD8041D supports IRNSS (NavIC), which makes it suitable for navigation in urban areas in India and the Middle East, where seven NavIC satellites have a higher elevation than both GPS and Galileo satellites. This means IRNSS (NavIC) would provide greater accuracy, precision and available measurements.
With the features of small size (3 x 3 millimeters) and low power consumption, the HD8040 series is suitable for smartphones, tablets and other portable devices.
The architecture integrates floating-point arithmetic units based on ARM CortexM4, 160 KB RAM, 32 KB backup RAM with VBAT, and 384 KB embedded Flash memory. Besides basic peripheral interfaces UART, I2C, SPI and GPIO, it supports the CAN interface for automotive applications, too.
Customer samples of the HD8040D and HD8041D are available now.
After many years of development at the fringe of the GNSS industry, dual-frequency GNSS devices are finally ready to hit the mass market and will account for more than a billion chipset shipments in 2023, according to a new market data report by ABI Research.
ABI Research is a market-foresight advisory firm.
The report finds that the bulk of this growth will come from the adoption in the smartphone market with consumers hungry for better location accuracy.
Dual-band GNSS can mitigate the multipath interference effects, which are especially present in areas with a high density of buildings, like urban canyons, and deliver significantly higher accuracy than single-frequency devices.

However, several obstacles prevented widespread adoption of dual-band GNSS until now, including insufficient satellite coverage of a second band, which could be L2 or L5/E5, high chipset prices, and challenges in fitting these integrated circuits and related antennas into small devices such as smartphones.
“On the availability side, this year has seen several satellites launched into orbit every month, most of them fitted with L5/E5 capabilities, and the Chinese and European Union governments plan to have their satellite constellations fully operational by 2020. L5/E5 devices will not be left in the dark,” said Henrique Rocha, a research analyst for Location Technologies at ABI Research.
Furthermore, new breakthroughs from key chipset manufacturers are disrupting this market by overcoming the barriers to mass dual-frequency adoption. With Location-Based Services (LBS) applications in mind, Broadcom has released the BCM47755 dual-band location hub, claiming the system’s architecture achieves the synergistic benefits that cannot be reached by multiple integrated circuits (ICs), thereby reducing its overall size and power consumption.
Other important players in this market have also come forward with dual-frequency solutions, including Qualcomm with the Snapdragon X24 LTE modem and HiSilicon with the Kirin 980 system-on-a-chip. Both attribute their superior energy efficiency and form factor to intelligent data processing and a FinFET transistor design. Other chipset manufacturers such as MediaTek are expected to follow suit and present their own dual-band products for LBS.

At the consumer level, considering the handset market is the largest GNSS segment, accounting for 85 percent of all GNSS chipset shipments in 2018, the launch of the dual-frequency Xiaomi Mi 8, Xiaomi Mi Mix 3 and the Huawei Mate 20 following such breakthroughs in the chipset industry is a significant development because it opens a new lane of competition between smartphone manufacturers.
It is expected that dual-frequency devices will dominate the high-end smartphone market in a matter of a few years, and by 2023 dual-band GNSS ICs will comprise 36% of total GNSS LBS IC shipments worldwide.
Triple-frequency chips. In other significant markets for multi-frequency GNSS, such as surveying and automotive applications, triple-frequency chipsets are being released, including STMicroelectronics’ TeseoAPP and u-blox’s F9. Adding a third frequency allows for better noise correction and higher accuracy compared to dual-frequency.

ABI Research believes that triple-frequency devices will see, at least for now, a relatively shy adoption as manufacturers will need to justify the cost and overcome the power issues they tackled for dual-frequency devices.
“For LBS the comparatively small accuracy gain going from dual- to triple-frequency GNSS is not worth the extra effort — for now. However, we will probably see triple-frequency GNSS take off when cars fitted with advanced driver assistance and autonomous driving systems begin to ship in large quantities,” added Rocha.
With full satellite operability of the main GNSS bands on the horizon and chipset manufacturers overcoming past hurdles for implementing dual-frequency solutions, it is likely a matter of time before most major companies in the segment scramble for a piece of this promising market. OEMs now need to show customers that dual-frequency GNSS can indeed deliver the accuracy they have promised so new location use cases can be sustained and introduced to the market.
New research conducted at the University of Otago, New Zealand, and published in the August issue of Journal of Geodesy demonstrate that it is possible to achieve centimeter(cm)-level precise positioning on a smartphone.
The research, conducted in collaboration with Curtin University, Australia, combined signals from four different GNSS, according to Otago’s Dr. Robert Odolinski and Curtin University colleague Prof. Peter Teunissen.
“It’s all down to the mathematics we applied to make the most of the relatively low-cost technology smartphones use to receive GNSS signals, combining data from American, Chinese, Japanese and European GNSS. We believe this new capability will revolutionize applications that require cm-level positioning,” Odolinski says.
He said to understand the new technology, a look back at the historical scientific context is needed.

The repeatability is more or less the size of a one-dollar New Zealand coin (diameter of 2.3 cm) in all three dimensions. (Image: University of Otago)
“For decades, construction, engineering, cadastral surveying and earthquake monitoring have relied on high-cost, dual-frequency GPS positioning to obtain centimeter-level location information. The challenge is that GPS signals, traveling from Earth-orbiting satellites to receivers on the ground, are disrupted along the way, and this generates errors and limiting precision.
“The traditional solution is to combine GPS signals sent at two different frequencies to improve the positions, but the antennas and receivers required have been expensive, far beyond the reach of many who would benefit from the technology,” Odolinski said.
The new approach uses only one of two frequencies but collects data from more satellites for a multi-constellation GNSS solution. The extra data and algorithms are used to improve the positions without adding cost.
Odolinski and Teunissen have shown that this approach can work in smartphones, producing competitive results compared to dual-frequency GPS solutions (see figure).
Odolinski believes that countries and industries of all sizes can benefit from using smartphones as GNSS receivers, and is confident commercial application and development will spring from this research.
“This significant reduction in costs when using smartphones can increase the number of receivers that can be deployed, which will revolutionize a range of disciplines requiring centimeter-level positioning, including precise car navigation, surveying and geophysics (deformation monitoring), to name a few.”
The Trimble Catalyst software-defined GNSS receiver for Android phones and tablets has been updated to support GLONASS. The update demonstrates the advantages of software GNSS for delivering new functionality faster and easier, according to Trimble.
Access to the GLONASS constellation increases the number of GNSS satellites visible when working in the field. As a result, it improves the ability to maintain lock on enough satellites to keep working when sky visibility is limited or obstructed, such as under tree canopy and in urban high-rise environments, Trimble said. Users also spend less time waiting for the receiver to achieve an accurate position, and convergence time is faster and more reliable.
Trimble Catalyst provides users with positioning-as-a-service to collect highly accurate location data with Trimble or third-party apps on Android smartphones and tablets. When combined with a small, lightweight, plug-and-play DA1 digital antenna and Catalyst subscription, the receiver provides on-demand GNSS positioning capabilities, and transforms consumer devices into centimeter-accurate mobile data collection systems.
“Adding GLONASS to Trimble Catalyst provides productivity improvements and more robust positioning for Catalyst users,” said Gareth Gibson, Catalyst business development manager at Trimble. “In addition, since the service is provided via an Android app, performance updates are available through the Google Play store. As a user, receiving updates is easy and automatic.”
Mobile brand Xiaomi has launched a dual-frequency GNSS smartphone.
Fitted with a Broadcom BCM47755 chip, the Xiaomi Mi 8 provides up to decimeter-level accuracy for location-based services and vehicle navigation, the company said.
The Mi 8 smartphone represents a breakthrough in GNSS technology as the first commercial deployment of Broadcom’s dual-frequency BCM47755 chip designed for the mass market and introduced in September 2017.
Until now, mobile location-based applications have been powered by single-frequency GNSS receivers whose location accuracy is limited to a few meters. However, in recent years GNSS systems have been launching satellites broadcasting signals on new frequencies to open up new possibilities. Specifically, Galileo has the majority of satellites with E1/L1 and E5/L5 frequency capabilities.
The E1/L1 + E5/L5 GNSS chip can compute location with an accuracy of up to a few decimeters.
Leveraging Galileo for increased accuracy
According to the company, users of the Xiaomi Mi 8 and future models with dual-frequency GNSS will benefit from better positioning and navigation experience in urban environments. This is due to the unique shape of the E5/L5 frequency, which makes it easier to distinguish real signals from the ones reflected by buildings, reducing the multipath effect, a major source of navigation error in cities and other challenging environments.
The numerous Galileo satellites broadcasting E5 make this improvement available for users all around the world. In addition, the simultaneous use of two frequencies reduces other sources of error, such as those due to the ionosphere, and the frequency diversity is more robust to interference and jamming.
In addition to making existing applications more accurate, the enhanced position precision offered by dual-frequency GNSS will also create opportunities for new applications in areas such as augmented reality, vehicle navigation and mapping.
Commenting on the product launch, European GNSS Agency (GSA) head of market development Gian Gherardo Calini said that the arrival of the first dual-frequency GNSS smartphone to the mass-market represents a breakthrough for users all over the world.
“The enhanced accuracy provided will empower developers to create new applications that meet the growing high-accuracy location requirements of users and also open up applications that previously only ran in dedicated devices intended for professional use,” Calini said.
“Broadcom is glad to gear up Xiaomi’s flagship smartphones with the very latest dual-frequency GNSS technology,” added Alex Chou, vice president of product marketing for the Wireless Communications and Connectivity Division at Broadcom. “Xiaomi Mi 8, the world’s first smartphone with BCM47755, will take smartphone GNSS navigation to a whole new performance level.”
”The importance of GNSS to modern life is undisputed, and is particularly important for smartphones,” said Zhiyuan Zang, Xiaomi’s director of product marketing. “Navigation and LBS-based apps these days require greater positioning accuracy to work effectively, and dual-frequency GNSS is the key to delivering a great user experience when using these apps. Xiaomi is delighted and honored to be the world’s first smartphone manufacturer to support dual-frequency GNSS. We will continue to pursue innovation for everyone to enjoy.”
Access to raw measurements for geolocation
The launch of the first dual-frequency GNSS smartphone, together with the opportunities offered by the availability of GNSS raw measurements in Android, creates exciting opportunities for the geolocation community, the company said.
Access to raw measurements opens the door to algorithms once restricted to more advanced GNSS receivers. This, in turn, allows users to fully benefit from the differentiators offered by Galileo.
Recognizing these opportunities, in 2017 the GSA engaged with academia and industry in the areas of navigation and positioning to innovate around this new feature as part of a GNSS Raw Measurements Task Force.
Then, in January, the GSA published a white paper on the use of GNSS Raw Measurements in Android, providing developers with in-depth information on accessing and using raw measurements to implement advanced GNSS techniques in mass-market devices.
Building on this work, the GSA and the Raw Measurements Taskforce shared their latest updates at a dedicated workshop — “GNSS Raw Measurements: From Research to Commercial Use” — held at the GSA headquarters in Prague on May 30, where Broadcom presented its encouraging test results from the dual-frequency BCM47755.
Tersus GNSS is now offering its David real-time kinematic (RTK) GNSS receiver with seven new base/rover kits.
Tersus GNSS is a provider of centimeter-accuracy GNSS RTK solutions. The Tersus David GNSS receiver with its components create an affordable solution delivering high-precision signal reception, integrated in a small, and lightweight package.
The David GNSS receiver supports GPS L1/L2, GLONASS G1/G2 and BeiDou B1/B2. With David, surveyors users can take full advantages of common platforms such as smartphones, tablets or traditional handheld modules to collect data.
Coupled with an external antenna, the Survey App and post-processing software, the David GNSS receiver is a low-cost solution for all survey applications, including real-time RTK positioning and data collection for PPK.
Four (4) GB on board an embedded multimedia card (eMMC) makes it easy to save data for post processing. The compact, IP67-rated enclosure and versatile accessories alleviate most inconveniences encountered in field work.
“The launch of David GNSS Receiver marks a major step forward for Tersus as well as for surveying professionals,” said Xiaohua Wen, founder and CEO of Tersus. “The David is a cost-efficient and palm-sized GNSS receiver. Tersus is constantly working to make each surveying task easier and more productive by providing high-quality GNSS RTK surveying equipment. Our focus is on enabling surveying professionals make data collection more convenient, post (data collection) processing more accurate, and better equipping them to do surveying in the field.”
This comment piqued my ears when heard over the coffee-break table at ION’s International Technical Meeting last month: “There is a great deal of mutual ignorance between the 5G and PNT communities. I think that the 5G people are pretty naive about PNT and the PNT community is missing an opportunity.”
So when news releases leading up to next week’s Mobile World Congress — several of them mentioning 5G in rosy terms, “catalyst for a better future” typical among these — started flooding my inbox this morning, it seemed an opportune time to investigate. Pardon my top-slice view; I’m not well-versed enough in the technology to discourse knowledgeably, but here’s quick round-up of salient points related to positioning in the fast-oncoming Next Step in cellular communications.
Regular contributing editor for Professional OEM and UAV Tony Murfin will return to this space next month, with a column previewing the massive AUVSI Xponential show in Denver, April 30–May 3. He’ll be there, too, covering the event!
The cellular 5G standard has been designed to target latencies under one millisecond, data rates of up to ten gigabits per second, extremely high network reliability, and better accuracy in positioning. With location awareness becoming an essential feature of many new markets, positioning is consequently considered as an integral part of the system design of upcoming 5G mobile networks.
Its feet firmly planted in both the present and the future, the cellular industry is currently in the midst of implementation of Long Term Evolution (LTE)-Advanced, an evolution of what might be called plain old LTE, and a “true 4G” mobile broadband. Simultaneously, the industry is preparing the next step, as “there is a vastly increased need for a new mobile communications system with even further enhanced capabilities, namely a fifth generation (5G) system.” 5G will process communication 10 times faster than 4G, according to experts. That’s enough to download a 3D movie in 30 seconds. It would take six minutes on 4G.
Pyeongchang
Alert techie viewers of the present ongoing Olympics in South Korea may have noted 5G in action there, in demos of such things as live-streaming virtual reality of bobsled and luge runs, putting the viewer in the breathtaking driver’s seat, and a test drive earlier this month from Seoul to Pyeongchang, a journey of several hours, without any human intervention whatsoever at the car’s controls. The demonstrations in Pyeongchang are laying down a backbone for what will be on show at the Tokyo Games in 2020, when 5G roll-out will be complete in many major metro areas.
As trumpets sound the fanfare for next week’s Mobile World Congress in Barcelona, AT&T announced it will first roll out 5G to three locations: Dallas, Texas; Waco, Texas; and Atlanta, Georgia. The plans introduce the service to about a dozen U.S. markets by late this year. Qualcomm meanwhile is offering insight into its 5G chips.
What has all this got to do with GNSS? Well, aside from the aforementioned precise positioning via cellular to be afforded by 5G, the two technologies share one prominent technique: adaptive array antennas for digital beam-forming. Here I am indebted to Gary McGraw of Rockwell Collins for a primer on the subject, which he presented at the International Technical Symposium on Navigation and Timing (ITSNT) in November 2016.
Adaptive array technologies have many advantages for PNT: primarily, in mitigation for multipath and for jamming and spoofing mitigation. Adaptive antenna arrays with digital beam-forming (DBF) are becoming increasingly important for PNT in challenging signal environments. DBF combines multiple antenna inputs to generate gain in arrival direction of the desired satellite signal and to create spatial nulls in direction of jamming.
Emerging applications of DBF in 5G involve dense networks of picocells, small cellular base stations typically covering a small indoor area. Picocells extend coverage where outdoor signals do not reach well, and add network capacity in areas with very dense phone usage. In this context, 5G cellular architectures will use adaptive array technology to achieve high data rates, spectrum reuse and communications robustness.
The implications for PNT are that 5G system architectures will require improved (relative) PNT to operate effectively, and these 5G picocells will be a source of PNT information in constrained environments.
5G involves massive directional communications via multiple-input multiple-output (MIMO), enabling high-bandwidth communications in fading (multipath) channels by using multiple antenna inputs to adapt to channel. It can do this without knowledge of user location, but it adds to the processing complexity. The directional capability can enable multiple users to be serviced in a picocell at different frequencies, while permitting spectrum re-use by nearby picocells through narrow beam-width and the limited range of millimeter-wave frequencies.
The PNT implications of 5G architectures, according to Gary McGraw of Rockwell, are, principally, that efficient operation of directional links will require some level of knowledge of user location with regard to picocells. Picocells will need to have the ability to do direction-of-arrival positioning and ranging in order to maintain connectivity with user nodes. This can be exploited by the user node for positioning and location-based services, particularly for indoor and dense urban environments. Meanwhile, the proliferation of adaptive array technology will drive down costs for other applications. Further, millimeter-wave transmit/receive modules will become commodity items, analogous to what cell phones have done for GPS chips.
McGraw’s Summary
5G picocells will be synergistic with PNT in challenged environments — naturally, indoor and dense urban. They will necessitate development of distributed, networked PNT processing and infrastructure. Availability of adaptive array technology will increase with deployment of 5G, and costs can be expected to drop dramatically. In addition to GNSS, adaptive array technologies can be employed to support short-range, relative PNT applications such as vehicle-to-vehicle communications and relative positioning.
Driving the Bus
The key driver for all this is that customers, the global We, expect the same quality of experience from Internet applications anytime, anywhere, and through any means of connectivity. The rapid proliferation of smartphones and other mobile devices that support a wide range of applications and services mean that image transfer and video-streaming, as well as more cloud-based services, such as cloud speech services, have become the new norm. Their requirement for massively more data than, say, simple texting is conveniently hidden from or forgotten by users. We want it. We want it now.
From a DOCOMO 5G White Paper: 5G Radio Access: Requirements, Concept and Technologies. NTT DOCOMO, INC., July 2014. At https://www.nttdocomo.co.jp/english/binary/pdf/corporate/technology/whitepaper_5g/DOCOMO_5G_White_Paper.pdf.
Tomorrow, or perhaps the next day, everything will be connected by wireless to enable monitoring and collection of information and control of devices. Thus, remote monitoring and real-time control of nearly all electronic devices in machine-to-machine (M2M) services and Internet of things (IoT): connected cars, connected homes, moving robots and sensors. Such services will become more extensive and enriched through richer content delivered in real-time. Get set for the tactile Internet, augmented reality, and other brave new wonders.
Fraunhofer Enters the Fray
The 5G positioning framework will thereby integrate a multitude of sensors based on both, cellular signals and 3GPP independent techniques, into a hybrid positioning scheme, according to the Fraunhofer Institute for Integrated Circuits (IIS) in Germany. Fraunhofer IIS is currently prototyping low-latency and high-precision positioning systems for legacy LTE and future 5G New Radio (NR). Two selected industrial IoT live demonstrations can be seen at next week’s Mobile World Congress 2018.

5G NR enables positioning performance by providing high bandwidths for precise timing, new frequency bands at mm-wave, massive MIMO for accurate angle-of-arrival estimation and new architectural options that support positioning. Improved levels of accuracy, robustness and latency, not possible today, can soon be achieved, according to Institute. 5G provides fast and reliable access to moving objects, to achieve time-critical process control and optimization in industrial environments not possible with today’s cellular technology. As requirements vary according to the specific use cases, 5G NR will provide a flexible air interface allowing for scalable bandwidths, data rates, latencies, and positioning accuracy levels.
High-Precision Positioning
With location awareness becoming an essential feature of many new markets, positioning is an integral part of the system design of 5G mobile networks. Increased contextual awareness of goods, parts, machines and workers will enable new interaction and collaboration.
High-precision positioning, in the view of Fraunhofer IIS. (Image: Fraunhofer IIS)
Fraunhofer IIS is working on novel approaches for sub-meter accuracy to enable tracking of mobile devices in indoor and urban areas where GNSS is not sufficiently accurate nor available. Its 5G positioning framework integrate several sensors. The key benefits of 5G in this regard are high accuracy, reliability, mobility and coverage; low latency and low power; and scalability.
The Institute offers the facilities of its Test and Application Center L.I.N.K. in Nuremberg, Germany. The test center includes a 3D positioning system capable, according to the organization, of reproducing, simulating and emulating all kinds of possible environments, using every common communication and positioning system commercially available.
The U.S. Supreme Court heard arguments last week on a case that could determine whether authorities can search cellphone location data without a warrant.
In Carpenter v. U.S., the Court will eventually rule on whether the Fourth Amendment of the U.S. Constitution’s Bill of Rights, enacted in 1791 to safeguard citizens’ rights against unreasonable searches and seizures, extends to cover personal cellphone records tracking user location.
The case began when police used records, obtained from a phone company and drawing on cell-tower location, to show that an individual’s cellphone was used in the vicinity of several armed robberies in Michigan and Ohio in 2010 and 2011.
The appellants contend that the government had violated the Fourth Amendment when it collected their cellphone location records without a warrant. A federal appeals court ruled against the appeal, finding the Fourth Amendment doesn’t “yet” extend to cellphone location data.
That court distinguished between the “content” of a communication and the “information necessary to send it.” The government can’t read letters or emails or listen to wiretapped conversation without a warrant, but it is entitled to the metadata used to send such content — in this case the phone company data showing in which tower’s cell area the phone was activated.
“The business records here fall on the unprotected side of this line. Those records say nothing about the content of any calls,” the court ruled. “Instead the records include routing information, which the wireless providers gathered in the ordinary course of business.”
The Supreme Court, in hearing the appeal on this decision, is expected to review — and possibly revise — its heretofore opinion that when users share information with a third party, such as a bank or telephone company, they lose the expectation that it will remain private. At question is whether cellphones have activated a new era of privacy expectations, in essence, whether legal doctrine needs to be subject to updates for the digital age.
One tenet that no one questions is that cell phone users have no idea to what extent their phone companies know where they go and how long they stay there. Whether they care or not, or whether they are willing to sacrifice some amount of privacy for the convenience of cell phone access, remains to be seen. The limits for this have been explored but never completely settled, in controversies around Facebook’s (and others’) access to and use of customer data and profiles.
Apple, Facebook, Google and Verizon have all filed an amicus (“friend of the court”) brief in Carpenter v. U.S. The tech gargantua seem to want, on the one hand, to discourage the possibility of government and law enforcement being able to access location data without a warrant, while also maintaining a clear and unencumbered route for themselves to use it. They argue that “Fourth Amendment doctrine must adapt to the changing realities of the digital era” and that “rigid analog-era rules should yield to consideration of reasonable expectations of privacy in the digital age.”
After a related 2012 Supreme Court decision that attaching a GPS tracker to a car without a search warrant violated the Fourth Amendment, Justice Sonia Sotomayor wrote that the so-called third-party doctrine was “ill suited to the digital age” and that privacy case law should adapt to changes in society’s views that are occurring thanks to smartphones and other technology.
For a summary of the arguments presented to the Court on November 29 in Carpenter v. U.S., see the SCOTUS blog here. Further developments in the case will appear on this page, and viewers may sign up for push updates as well.
In 2008, GPS World published an editorial on this subject, in the guise of a parodized future film noir scenario, “The Call Tease Factor.” An expandable image appears at left. The essay opined that “Government agencies and police routinely tracked cell users’ location without a warrant or court oversight. . . . Challenges had faltered, and no one seemed to notice any more, or care much.”
“Privacy, as least as far as location, no longer existed.”
Wyzelink Systems’ IoT workflow-automation application, WyzeTask, is now available in the Geotab Marketplace. WyzeTask is the newest application in the marketplace and is a complement to the MyGeotab platform, which serves more than 14,000 Geotab customers.

StepInside and partner Flowscape to help Sweden HQ team easily find available workspace and colleagues
The Senion StepInside indoor positioning system has been deployed in the 500,000-square-foot Kista (Stockholm) headquarters of telecom company Ericsson.
Using personal or work-issued smartphones, more than 4,000 employees working throughout 20 floors distributed over four buildings can now use a corporate app to easily find available rooms and spaces to work, the company said.
The indoor positioning system is designed by Senion’s longtime partner Flowscape. With StepInside integrated into the Flowscape platform, the two companies will help Ericsson employees reduce wasted time searching for people, places or things, increasing productivity.
The StepInside software development kit (SDK) offers location readings in latitude, longitude and floor level in real time. The SDK can easily be integrated into any smartphone application. StepInside relies on an advanced sensor fusion algorithm that works with the smartphone’s movement and radio sensors to provide accurate and robust positioning.
“Indoor positioning technology is perfect for large offices with multiple floors, offices, and meeting spaces — the bigger and more intricate the better,” said Christian Lundquist, CEO and co-founder of Senion. “We’re seeing that large companies are taking serious measures to combat friction in order to increase both productivity and employee satisfaction. We now aid Ericsson in giving back time to their employees so they can be more efficient in their day-to-day work.”
The implementation of StepInside at Ericsson is part of the company’s larger global platform designed to enable rapid IoT application development.
“We looked carefully at the benefits of using IPS [indoor positioning system] in our offices, and determined the system would pay for itself in productivity savings alone,” said Magnus Arlidsson, global head application platform for IoT at Ericsson. “Our initial roll-out focuses on productivity improvements by saving employees time they might waste searching for things, such as conference rooms or places to work.”
The system as implemented today is the starting point for a bigger roll-out with additional workplace enhancements at Ericsson.
Senion’s comprehensive IPS services include analytics, wayfinding, geofencing, friend finder and tracking. With more than 300 indoor positioning system installations globally, Senion has worked closely with shopping malls, hospitals, corporate campuses and more to improve workflows. Senion is headquartered in Linkoping, Sweden, and San Francisco.
“Connect your compatible smartphone to the center display to access select apps, your calendar and playlists or navigate with Google Maps.”
That’s the description of the navigation offering on the official Chevrolet Bolt website. One of General Motor’s (GM) most advanced vehicles, the electric Bolt doesn’t offer native GPS navigation as an option.
As H. Kesteloo of Electrek blogs, almost all new vehicles for sale in the United States either come with GPS navigation or offer it as an option. GM is betting that Bolt drivers will prefer their smartphones over built-in GPS systems.
Is it a risk? Probably not, considering that apps such as Waze, Google Maps or Apple Maps are more frequently updated, offer real-time traffic information and are often easier to use than factory-installed systems. Plus, the apps are free (with a data plan, of course) compared to a feature that once cost as much as $2,000 on a new car.
Instead, Chevrolet is offering Android Auto and Apple’s CarPlay, which seamlessly integrate the Apple and Google built-in maps apps — all of which assumes the driver has a smartphone charged, ready and in range of a wirelss connection.
“Will this be the beginning of a new trend?” Kesteloo asks. “Are we going to see more vehicles without integrated GPS navigation offerings? Perhaps offering a built-in $300 iPad Mini makes sense — the Bolt already has its own wireless internet connection.
“With a future of self-driving cars quickly approaching, native GPS will still be a critical component,” he notes.
