    Aman Enterprises introduces NMEA-BT — a Bluetooth iOS adapter that enables any high-precision GNSS receiver with a serial port to connect to an iPad or iPhone.

    The NMEA-BT adapter is a small, weatherproof device that solves the problem of connecting non-iOS GNSS receivers and other field sensors to iOS devices. It connects to the iOS devices wirelessly using the native Bluetooth built into the iOS devices.

    GPS World reported on a Kickstarter campaign to develop the device in January 2015. The device is now shipping.

    By replacing the iOS device’s internal GPS location information with the location information from the intrinsically more accurate external GNSS devices used by mapping and survey professionals, NMEA-BT allows users to pair external GNSS devices to their location-enabled iPhone or iPad app. The patent-pending product helps preserve the user’s investment in sub-meter and centimeter GNSS receivers and other sensors while users migrate their workforce to iOS devices.

    A free app from the Apple iTunes App Store (NMEA Talker) enables the user to specify any required GPS connection parameters; connect to a local cellular RTK network (NTRIP) or a Direct IP (DIP) based correction service; and feed the corrections to the GNSS receiver, allowing for centimeter accuracy in real time in the field. The app can also be used to display error notifications like high PDOP, loss of an RTK correction, loss of satellite lock.

    In addition to connecting to GNSS devices, users can connect to other sensors like laser rangefinders, resistographs, underground cable locators, and commercial weigh scales that output NMEA-formatted data.

    For developers, they have full access to the entire raw NMEA stream of data from multiple devices without sacrificing app security or design architecture. No proprietary libraries are required to access the NMEA data stream.

    GPS/GNSS Receiver Compatibility

    The NMEA-BT has been tested with the following receivers:

    • John Deere StarFire
    • Trimble Pro 6, Geo Explorer, 372
    • Casel H372
    • Topcon HiPer series
    • Septentrio APS and NR series
    • Geneq SXBlue series
    • Ag Leader 6000 and 6500 series
    • Raven Industries – Envizio Pro series
    • Novatel

    The only requirement to interface the NMEA-BT adapter is that the GNSS receiver must output at least the $GPGGA and $GPRMC messages via serial port.

    TobyRich has integrated OriginGPS’ Nano Hornet into a smartphone-controlled gaming drone line, to extend its range and enhance its directional capabilities. By leveraging the Nano Hornet, a tiny GPS module with an integrated antenna, TobyRich was able to design a smaller, sleeker form factor for its innovative drones while taking advantage of OriginGPS’ performance and low-power consumption features, according to TobyRich.

    TobyRich, established in 2011 and with deep experience in designing smartphone-controlled drones, launched a Kickstarter campaign that will run until Aug. 28 to offer a new, more interactive experience for video gamers and drone enthusiasts across the globe.

    The agile drones blend realistic flight maneuvers with innovative interactive gameplay and are designed to resemble an airplane rather than a quadcopter to extend flight time and carry more payload than traditional drones without compromising on functionality or performance. The drones can easily be controlled within a range of 90 meters via the tobyrich.red mobile app, which is available on iOS and Android.

    TobyRich’s drones combine the immersive experience of video games with the exhilaration of real flight to unlock possibilities such as mid-air battles, races, stunts and other gaming scenarios, plus additional applications such as aerial photography and video, the company said. Single and multiplayer gaming modes enable video gamers to live out their flight fantasies with friends or solo. To meet users’ exact interests, several different versions are in development, including the basic tobyrich.vegas model, tobyrich.tokyo, which features a HD camera, and tobyrich.guru, a 4G/LTE-enabled drone.

    With the help of OriginGPS, a TobyRich drone knows exactly where it is in relation to a user’s smart device, with unprecedented accuracy, allowing it to respond immediately and precisely to gesture controls or on-screen joysticks. OriginGPS’ location capabilities ensure that a drone will automatically return to its point of origin or a pre-programmed destination if it strays too far from its corresponding smart device or flight path, which reduces user frustration, minimizes human error and increases safety.

    Measuring 10 by 10 millimeters, the OriginGPS Nano Hornet module powers TobyRich’s flight management system by achieving a rapid time to first fix (TTFF) of less than one second, with approximately 1 meter accuracy and -163 dBm tracking sensitivity, and it uses OriginGPS’ proprietary Noise Free Zone technology to increase sensitivity and minimize interference. It achieves a state of near continuous availability, while consuming microwatts of battery power, ensuring maximal power is devoted to increasing drone flight times. Because OriginGPS’ modules are complete, plug-and-play solutions, they significantly shorten time to market and dramatically reduce engineering risks, the companies said.

  • Kickstarter Launched for NMEA Dongle to Connect GPS, iOS

    Kickstarter Launched for NMEA Dongle to Connect GPS, iOS

    kickstarter campaign has launched for an NMEA dongle that connects any existing GPS receiver to iOS devices. The device connects and communicates with high-accuracy GPS/GNSS devices and other field sensors that emit NMEA data to iOS devices over Bluetooth, allowing users to collect data on an iPad or iPhone using one or more sensors in the field.

    Primary functions include:

    • overriding the internal GPS on iOS device with the location data coming from the external GPS so all existing apps using internal location services can benefit from the increased accuracy without any changes to the app.
    • providing the ability to connect with other field sensors that emit NMEA-format data (such as underground cable locators, lasers, resistographs, and audiographs) simultaneously with a GPS so data from multiple sensors can be incorporated into the data-collection application.

    Garg explained the need for the dongle on his Kickstarter page: “The accuracy and precision of the internal GPS on iPads and iPhones is highly unreliable — it works fine for navigational purposes but fails miserably for mapping and asset management applications. The accuracy varies in range from a few meters to a few hundred meters depending on operating conditions, and there is no easy way to reliably ascertain that. Tests have proven that the accuracy rating on the location data returned by Apple is more of a general estimate than a reliable metric.”

    The NMEA dongle is business-card-sized, and has an internal battery and a long-range Bluetooth. The dongle plusg into an existing GPS receiver’s serial port or connects via bluetooth to transmit the GPS data to the iPad. This allows users to feed RTK/NTRIP data to their iOS device.

    “We have tested our solution with most of the leading brands of GPS receivers available in U.S., including Trimble, Topcon, John Deere, Altus, Geneq, EOS, CHC,” developer Sharad Garg told GPS World, “on most of the popular networks that we could get access to, including the Leica, Trimble, MyWayRTK, a few state-run networks and of course Unavco. Our solution is compatible with all of them, so its a very generic product at this point compatible with just about all the different solutions out there.”

    Garg said his team also designed the dongle so that it allows users to connect to sensors such as laser range finders, valve exercising machine, Resistographs or agricultural sensors that emit data in NMEA format. The National Marine Electronics Association (NMEA) specification defines the interface between various pieces of marine electronic equipment, a standard that permits marine electronics to send information to computers and to other marine equipment.

    “We have actually improved the design very significantly to be very modular and be compatible with all sorts of GPS connections that might be offered by the different vendors out there,” Garg said.

    This YouTube video shows the dongle’s RTK functionality.

  • What Happened to Piksi, the $995 RTK GNSS Receiver on Kickstarter?

    What Happened to Piksi, the $995 RTK GNSS Receiver on Kickstarter?

    A little more than a year ago, Swift Navigation started a Kickstarter campaign for a $995 RTK GNSS receiver named Piksi. The goal was to raise $14,000 for the project. By the time the Kickstarter campaign was ended, Swift raised $166,097 from 303 backers.

    I wrote an article about the Swift’s Kickstarter campaign in September 2013, a few days before the fundraising period ended. Following is a two-minute Kickstarter promotional video describing Piksi.

    At the time, the $995 price for the Piksi raised a lot of eyebrows and generated conversations in the high-precision GNSS user community about inexpensive RTK technology.

    This week, I took the opportunity to catch up with Swift to see how the project is going and where the company is headed.

    I spoke with Tim Harris, CEO of Swift, and Fergus Noble, chief technology officer. Tim said they delivered most systems to their backers in April (2014) as well as issuing “very few” refunds, which is not unusual for Kickstarter projects. As of today, Tim said there are about 1,000 units in the field among 350+ users. He said they still consider the Piksi to be in beta testing phase and expect production units to start shipping next year.

    “We are in RTK reliability mode now” — Fergus Noble

    Fergus said that the hardware design is stable and hasn’t changed since they shipped Piksi last spring. He said the focus has been on refining the RTK firmware to make it robust and reliable for professional use. He admits that “covering all corners” has been a challenge and, according to Swift’s blog, “The RTK software has been a tougher nut to crack than we originally anticipated.” This is especially ambitious, since Swift said they developed the RTK firmware based on published academic technical papers, combined with their own techniques (preparing patent applications) to run on a low-power hardware platform. Basically, they started from scratch, and without any RTK veterans on their team. You gotta love their guts.

    Apparently, the venture capital world liked what they saw. A few months ago, Swift, based in San Francisco, secured $2.6m in seed funding from Fall Line Capital, Felicis Ventures, Kal Vepuri, Lemnos Labs, Qualcomm Ventures and VegasTechFund. With the additional funding, Swift has increased its headcount from 4 to 9.5.

    The Devil Is in the Details

    Start-ups like these are a cool story, but at some point the rubber has to hit the road. Piksi is a long way from being an RTK product that you and I use for GIS and surveying, and Tim/Fergus are humble enough to admit this. The founders see the Unmanned Aerial Systems (UAS) market as their key customer base due to Piksi’s micro-size and low cost. They say this is reflected in their current customer base, which is comprised largely of UAS users, then surveying and agriculture, with the remaining 20 percent being a variety of apps like augmented reality. I agree that UAS is the right segment for them to focus on. At this point, the limitations for general surveying and GIS use are too great:

    • Must use a Piksi RTK base due to the proprietary protocol. In other words, not compatible with existing RTK base stations or networks.
    • Baseline length (distance between the RTK base and rover) must be very short. They haven’t done much testing even with a one-mile baseline.
    • RTK initialization is spec’d at 15 minutes, although Fergus said it’s typically 7-10 minutes.

    Since Piksi is only a single-frequency receiver (L1), it has the same limitations as other L1 RTK systems we’ve seen marketed over the past few years — short baselines and long initialization times compared to dual-frequency receivers. While these limitations are significant for surveying and GIS users, they aren’t as significant for UAS users, since UAS users require line of sight to the aircraft at all times and UAS are operated in a clear-sky environment.

    Communications

    If you’ve used RTK, you are aware of the importance of data communications between the base and rover. As part of its kit, Swift supplies license-free, 915MHz frequency-hopping radios to facilitate communications between the base and rover for testing. However, the founderse make it clear that they aren’t in the data radio business. They expect that most Piksi users will incorporate their own communications technology. Swift is discussing incorporating GSM (mobile phone) modem capabilities in the future.

    Future

    In 2015, Swift plans to roll out the Piksi in production quantities, so Fergus said their focus is on creating a robust and professional RTK system. Of course, the burning question is if/when Swift will incorporate a second GPS frequency into its receiver to take advantage of the faster RTK initialization and longer baseline distances that a dual-frequency receiver offers. Swift isn’t willing to talk about that right now. Said Tim, “We’re holding our plans close to our chest.”

    Thanks, and see you next month.

  • Kickstarter Comes to GPS; Plus, Jammers and Field Technology Conference

    $2,000 for an RTK base and rover? Yes, it’s real. Well, at least it seems real.

    For $2,000, you can order an RTK base and rover set named Piksi, including radios.

    It’s an intriguing opportunity, and might be the first brush stroke of the picture I’ve been painting (metaphorically speaking) for the past few years about inexpensive RTK receivers forthcoming. But, before you get really excited, read on.

    Besides the attractive price, something else that makes Piksi interesting is the way the company is financed. The way that a typical company funds new product development is through its own cash flow or financing. The company designs and produces a product, then announces it to potential buyers (you), who then touch, feel and use the product to understand how it performs…all before making the decision to purchase. Piksi (Swift Navigation) doesn’t follow that model.

    Piksi is using a new-age, crowd-sourced funding model called Kickstarter. With Kickstarter, a group of people (creators) offer to design and produce a certain product if they can recruit enough “investors” to fund their endeavor. The “investors” aren’t traditional venture capitalists, nor people who would own stock in said company. The investment is simply a commitment to buy the product based on the specifications provided by the creators, before the product is finished. If the company has enough commitments from “investors,” the creators commit to designing, building and delivering the product.

    Furthermore, there are certain levels of investment available for Piksi, from $7 which will get you a Swift Navigation micro-USB cable, to $2,000, which will get you a ruggedized version of the complete RTK kit, including base, rover, XBee radios, Bluetooth and SD card storage. So far, Swift Navigation has raised $161,369 towards the project with today, September 4, being the last day. That’s far more than the $14,000 goal it set.

    The caveat is that the product is not complete yet, at least the RTK portion. According to Swift Navigation:

    We have already built a small batch of Piksi receivers that are ready to ship and have locked down all part sourcing and manufacturing for further batches, so there are unlikely to be any unanticipated delays in the delivery of Piksi hardware.

    However, it’s difficult to know exactly how long the RTK functionality will take to implement — software development schedules seem to always run over their anticipated delivery dates, even when you take into account Hofstadter’s Law. We feel the goals we’re proposing to accomplish with this campaign are reasonable — adding a new set of software functionality (which we successfully implemented on a previous platform) upon an existing base of stable hardware and software.

    The gamble that the investor takes is that Swift will be able to finish the product, produce it, and meet the performance specifications. However, that’s only part of the battle. I spent better than 10 years of my life managing the design and production (somewhat) of GPS-based hardware and software for mapping and surveying. There are a million details. A major part of developing a hardware/software product like this is making it reliable. What I mean by reliable is that it behaves the same way every time you push the ON button, and works consistently and reliably all day until you press the OFF button. That’s not easy to achieve without a lot of sophisticated testing in different environments, and nothing can fix a poor reliability design (except a redesign).

    The guys behind the Piksi don’t seem to be total GPS-rookies, but do lack substantial real-world experience. Click here and then click on Bios to read about their backgrounds. But who knows? Maybe that’s an advantage, not being conditioned to “follow the rules.”

    One last note, and an important one. It’s only an L1 system, so don’t get too excited. L1 means that you really can’t use an RTK network (practically speaking) and that the baseline distance needs to be pretty short. The RTK initialization and re-initialization times will be measured in minutes, not seconds, and that’s assuming they get the RTK algorithms correct (and reliable).

    Sorry to burst your bubble.

    Actually, the concept of an inexpensive, bootstrapped L1 RTK system is not difficult to envision. The GPS OEM boards are readily available, as well as the GPS antennae, wireless comms and the rest of the components. At the risk of sounding pompous, I could put that kind of project together. The trickiest part of the project would be developing/implementing reliable RTK software.

    No matter what, it will be interesting to hear about what these guys come up with. In the words of the late Steve Jobs, “stay hungry, stay foolish.”

    GPS jammers are cheap, but don’t get caught using one.

    Even though they are illegal to market, sell and operate in the U.S., Americans are buying cheap GPS jammers, via Internet stores, from companies operating outside of the U.S. Operating one of these devices in the U.S. is a risky venture (as you’ll read below).

     

    Although they don’t seem to be a serious threat yet, they could become a threat as GPS receivers become more ubiquitous and concerns about privacy continue to ramp up.

    The Federal Communications Commission (FCC) is responsible for enforcing the U.S. laws enacted that prohibit the use of GPS jamming devices. If you look at the FCC’s enforcement history here, you’ll see that there isn’t much enforcement activity. However, a recent enforcement action was imposed on a guy in New Jersey who made the mistake of driving by the Newark International airport with his GPS jammer turned on. Uh oh. The FCC tracked down the offender and issued a Notice of Apparent Liability for Forfeiture that included a fine of nearly $32,000. Whoa, that’s a lot of dough. Wonder if he is trying to sue the company he bought it from? Not likely, as they are most certainly outside of the U.S. and out of reach of the U.S. judicial system. Caveat emptor.

    You can be assured that if jamming reports increase, there will be more jamming detection and location equipment deployed to hold people accountable, like this new, handheld GPS jammer detector and locator from Chronos:

    You might want to visit this GPS.GOV website on GPS jamming. It contains a lot of information about the U.S. regulations surrounding the marketing, sales and use of GPS (and cell phone) jamming devices.

    Third annual Field Technology Conference

    FTC2013_logo

    In 2010, I, along with two colleagues, put together a conference here in Portland, Oregon, and named it the Field Technology Conference. We created the conference to focus on geospatial technology hardware and software used in the field. It’s the essence of what a conference should be, a group of people gathering to share ideas of common interest. It’s mostly devoid of commercial interests, save a few really neat (and valuable) giveaways and a few exhibit booths. You probably haven’t heard about the conference because we have a very small marketing budget, and the organizers (three of us) can only spend a few hours a month brainstorming, finding speakers, and organizing the event.

    This year, our third, will focus on existing and emerging technologies: GPS/GNSS, UAVs, 3D printing, mobile devices, imagery and geospatial software. Our outdoor demonstration area was very popular last year so we’ll offer that again, as well as a UAV demonstration. We’re also planning an on-site demonstration of 3D printing. Can you imagine 3D printing a topographic survey?

    Something new this year is our association with the CGSIC (Civil GPS Service Interface Committee). CGSIC is co-locating a regional event with our conference. What that means is that speakers from the U.S. government (Air Force, State Deptartment, DOT, etc.) will make GPS-centric presentations. CGSIC events are the only live communication channel between the U.S. Air Force GPS operations personnel and civilian GPS users. This is your chance to ask Air Force personnel questions, in person, that you’ve always wanted to know about GPS. If you’re unable to travel to Portland for the conference (October 23-24), GPS World magazine is planning on streaming the CGSIC presentations live over the Internet, as well as posting the recording on its website.

    Although the conference is organized by the Western Forestry and Conservation Association (which organizes a lot of conferences), take a look at the agenda and you’ll see the content will be of interest to anyone involved with geospatial data collection and processing technology, not just foresters and environmental scientists.

    Thanks, and see you next month.
