    Swift ​​Navigation has upgraded the firmware to ​​its flagship product — the Piksi Multi GNSS ​​receiver. This marks the sixth major release to Piksi Multi since it was launched in February 2017.

    The upgrade is available free of charge to Swift customers. ​​

    The firmware release also enhances Duro, the ruggedized version of the Piksi Multi receiver housed in a military-grade, weatherproof enclosure for long-term outdoor deployments.

    Swift ​​Navigation is a ​​San ​​Francisco-based ​​tech ​​firm building centimeter-accurate ​​GNSS ​​technology and a cloud-based corrections service​​ to ​​power ​​a ​​world ​​of ​​autonomous ​​vehicles, the company said. ​​

    Firmware Release 2.0 for Piksi Multi and Duro supports two additional major satellite constellations — the Chinese constellation (BeiDou B1/B2) which, once completed, will contain 37 satellites and the European Union-based constellation (Galileo E1/E5b), which will eventually consist of 30 satellites.

    Adding to the existing GPS, GLONASS and SBAS constellations already supported by Swift’s GNSS receivers means that users will have more access and visibility from satellite systems across the globe.

    Piksi Multi’s performance will further improve over time as the total of 136 satellites planned for these major constellations are fully deployed.

    The addition of BeiDou and Galileo constellations creates more robust positioning performance in a variety of challenging skyview environments and puts Piksi Multi on par with leading industry receivers costing up to ten times a much.

    With this 2.0 release, Piksi Multi is feature-complete, and Swift’s engineering team has delivered on planned product features on the Piksi Multi Product Summary.

    Firmware ​​Version ​​2.0 ​​Enhanced Receiver Performance Highlights

    MSM Messages 4-7. The ​​new ​​firmware ​​adds support for RTCM 3.2 Multi Signal Messages (MSM). Though Swift devices already support RTCM 3.1, the addition of MSM allows for another flavor of differential corrections supported by BeiDou and Galileo, while also supporting both GPS and GLONASS with MSM new messages. MSM also allows for interoperability with other existing third-party GNSS receivers for all modern signals and constellations.

    Fix Improvements. Firmware 2.0 provides Piksi Multi and Duro improvements on fixing in long base lines in poor atmospheric conditions, making the devices more resilient to Ionospheric effects during periods of high Ionospheric activity.

    Higher Baud Rate Support for UART. New baud rates were added including 460800 and 921600.

    Acquisition Improvements. Enhancements made allow Piksi Multi and Duro to power on to a usable signal more quickly and acquire satellites in start-up mode faster, by several seconds.

    “The growing Swift engineering team has been hard at work developing Piksi Multi to its full potential,” said Samir Kapoor, executive vice president of engineering and product at Swift Navigation. “With support for all modern satellite constellations and multiple performance improvements, Piksi Multi offers unmatched affordability, priced at ten times the savings yet on par with other leading GNSS receivers.”

    “Swift’s vision of making GNSS devices that are centimeter-accurate, with fast RTK convergence times and robust positioning performance all at highly-competitive prices has come to fruition,” Kapoor said. “With Piksi Multi feature complete, we look forward to adding to our line of products with additional offerings later this year.” ​

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

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

    Piksi

    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:

    Chronos_ctl3520

    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.
