Research Roundup: Guiding vehicles on busy city streets

Image: NatalyaBurova/iStock/Getty Images Plus/Getty Images

Of the hundreds of papers researchers presented at the Institute of Navigation’s annual ION GNSS+ conference, which took place virtually Sept. 21–25, the following four focused on autonomous vehicle positioning for automobiles on city streets. The papers are available at www.ion.org/publications/browse.cfm.

Digital Maps with Tethered Positioning

The authors propose a new method for tight integration of digital map and dead-reckoning (DR) system (inertial measurement unit plus wheel odometer) to provide reliable navigation solutions in challenging GNSS environments for extended periods. Integrated DR and GNSS have been widely used as the backbone of any navigation system for the internet of things (IoT) and vehicle navigation applications. Dollar-level micro-electro-mechanical system (MEMS) inertial measurement units (IMUs) aided by vehicle-wheel odometers have been recently used as low-cost DR systems to bridge GNSS gaps in harsh environments, such as urban canyons, tunnels and under bridges.

However, DR drift errors rapidly increase over time and cannot satisfy most IoT and land-vehicle navigation requirements. Plus, the GNSS receiver may fail to provide accurate position or even experience a complete outage for more than 15 minutes, causing the tethered positioning error to reach several hundred meters. Because land vehicles are supposed to travel on roads, feedback from a digital map can be used to constrain their position.

The authors used a fuzzy-logic map-matching algorithm to identify the correct road segment on which the vehicle moves. A feedback filter senses a correct map-matched position as well as the road segment as measurement updates to the Kalman filter (KF) of the tethered positioning system. The proposed tight integration of digital maps and a DR system is evaluated using datasets collected by Profound Positioning Inc. in Calgary, Alberta, Canada. Results show the proposed method has an average of 0.15% of relative horizontal position error for Calgary datasets — a considerable improvement over the tethered-solution-only with 3.3% of relative horizontal position error. The average azimuth error of the proposed system is 1.3 degrees, while the tethered positioning system shows an average azimuth error of 9.7 degrees.

5G Signals for Opportunistic Navigation

This paper presents a navigation framework in which 5G signals are used for navigation purposes in an opportunistic fashion. A carrier-aided code-based software-defined receiver (SDR) produces navigation observables from received downlink 5G signals. The SDR produces navigation observables from 5G signals and a navigation filter in which the observables are processed to estimate the user equipment’s position and velocity.

An experiment was conducted on a ground vehicle to assess the navigation performance of 5G signals. In the experiment, the vehicle-mounted receiver navigated using 5G signals from two 5G base stations (also known as gNodeBs, or gNBs) for 1.02 km in 100 seconds. The proposed 5G navigation framework demonstrated a position root-mean-squared error of 14.93 m, while listening to signals from only two gNBs.

Using Low-Cost Onboard Sensors

For autonomous vehicles, accurate positioning must be ubiquitous — reliably available at all times and in all places in which the vehicle is expected to operate. While GNSS commonly provides the basis for absolute positioning, it suffers from the problem of availability whenever a direct view of enough satellites is not possible. To address this failure mode, additional complementary sensors can be added to the overall navigation solution through a technique known as sensor fusion. Sensors such as inertial measurement units (IMUs), cameras, lidars, radar and more can be selected in such a way that the individual shortcomings of each sensor are mitigated, and the overall robustness and reliability are improved.

Although current autonomous-vehicle applications employ sensor-fusion techniques, they tend to rely on high-performance sensors to meet the accuracy requirements. These high-performance sensors tend to induce a much higher cost burden than would be acceptable for commercial production, and therefore make mass autonomy too expensive.
This paper focuses on using the lower cost sensors already available on most modern vehicles. These include low-resolution odometry and consumer-grade IMUs currently used for dynamic stability control and wheel-slip detection. A novel approach for combining vehicle speed, steering angles, transmission settings and multiple odometry inputs is presented along with achievable results while operating under a GNSS-denied environment. The test trajectory mimics a typical parking structure with many corners and short, straight segments. The only a priori information required for the filter is the wheel track and wheelbase (separation distance of the wheels).

A 90% performance improvement compared to the stand-alone GNSS/INS solution was observed during GNSS outages of up to 30 minutes. Furthermore, up to a 50% improvement was observed when comparing the multi-odometry to the single-odometry outages during the same 30-minute outage condition. Beyond GNSS outage performance, this paper shows how the use of the extra input to the filter can improve the positioning system’s protection levels to allow for more frequent engagement of the autonomous navigation system.

Radar and INS/GNSS

An autonomous vehicle requires a ubiquitous, accurate, precise and reliable localization system. Many sensors can be used for positioning and navigation, each with its strengths and weaknesses. Inertial measurement units (IMU) are usually used to build inertial navigation systems (INS). INS can be accurate for short durations; however, an INS accumulates errors and loses its accuracy quickly, especially when using low-cost MEMS-based sensors. GNSS can provide an absolute position and velocity to update the INS over time. A barometer provides absolute elevation information, and an odometer provides a speed update.

An integrated navigation solution consisting of an IMU, a GNSS-RTK receiver and odometer can perform well in open-sky areas and on highways. This system can achieve lane-level accuracy most of the time based on the condition of the sensors and the quality of the measurements. However, in downtown and urban environments, the degradation, multipath and blockage of the GNSS signal leads to poor performance for such an integrated navigation system, which is challenged to maintain lane-level positioning.

This paper presents a version of AUTO (formerly known as Coursa Drive), a real-time integrated navigation system that provides an accurate, reliable, high-rate and continuous navigation solution for autonomous vehicles by integrating INS, RTK GNSS, odometer and radar sensors with TomTom’s HD Maps. AUTO performs a tight nonlinear integration of the radar data and maps with the INS/GNSS/odometer system.

Results demonstrate that radar measurements and HD Maps can be tightly integrated with INS/GNSS in an effective manner, such that the integrated system can provide a high-rate, accurate, reliable and robust navigation solution. This is a crucial requirement for realizing a fully autonomous vehicle that can operate in urban environments under a wide range of conditions, including adverse weather and lighting conditions, even in downtown areas with degraded or denied GNSS signals.

Iridium invests in DDK Positioning, a GNSS solution provider

DDK Positioning solutions use the Iridium satellite constellation to deliver 5-cm GNSS accuracy to industrial users of the internet of things (IoT).

Iridium Communications Inc. has made a strategic investment in DDK Positioning, an Aberdeen, Scotland-based provider of enhanced GNSS accuracy solutions.

DDK uses the Iridium network to provide global precision-positioning services that can augment GNSS constellations, including GPS and Galileo, to significantly enhance their accuracy for critical industrial applications.

DDK is developing similar services for other GNSS constellations, such as GLONASS and Beidou. Terms of the investment are not being disclosed.

Standard positioning accuracy through a system like GPS is typically within 10 meters; however, by using the Iridium network, DDK’s enhanced GPS accuracy service brings incredibly precise positioning of 5 cm or less. This advanced level of accuracy is suitable for autonomous vehicles such as UAVs, precision agriculture applications, offshore infrastructure projects such as wind-farm construction, automotive applications like driverless cars, as well as a host of construction, mining, surveying and IoT use cases.

Historically, there have been limited geostationary satellite provider options for this type of service, but they suffer from line-of-sight blockage issues and coverage limitations in and around Arctic and Antarctic regions.

“We are delighted to have embarked on this journey with such a strong and well-respected company as Iridium,” said Kevin Gaffney, CEO of DDK Positioning. “This partnership is a perfect fit for DDK Positioning. With Iridium’s satellite communications network and our GNSS solution, we are in a position to deliver a truly unique service which is robust, resilient and secure. The investment made by Iridium will also allow us to grow the company even further whilst expanding our service offering globally.”

According to a report published by the European GNSS Agency, augmentation services like those offered by DDK will account for $76.5 billion (€65 billion) in global GNSS market revenue by 2029, while the global GNSS downstream market, including services delivered and hardware devices, is estimated to reach $382 billion (€325 billion).

“We are impressed with the team that DDK has put together and see great potential for this technology and how it takes advantage of the Iridium network,” said Iridium CEO Matt Desch. “DDK’s enhanced positioning is a unique capability that adds a high-value solution on top of our existing portfolio of custom network services. Solutions from Iridium and DDK partners that are focused on precision agriculture, autonomous systems, maritime and infrastructure projects can now experience incredibly precise GNSS accuracy from anywhere on the planet.”

Hexagon | NovAtel has released the GAJT-410MS in response to the increase of interference and jamming in marine environments worldwide. The GAJT-410MS is the company’s latest addition to its proven GPS Anti-Jam Technology (GAJT) for the commercial and defense marine markets.

The low size, weight and power (SWaP) variant protects civil and military operations from interference and jamming, with jammer direction-finding capabilities for enhanced situational awareness in the marine environment.

The GAJT-410MS provides dynamic protection on both GPS L1 and L2 bands, as well as Galileo E1, QZSS L1 and L2 and SBAS L1 to combat intentional and unintentional interference. If a vessel experiences jamming, the device’s direction-finding capabilities provide improved situation awareness of their RF environment to identify and locate the source of the jamming signals.

The commercial off-the-shelf, non-ITAR solution is easy to install or retrofit onto existing fleets, enabling assured PNT for continuous operations, cybersecurity and safe navigation at sea, NovAtel said.

Interference, both benign and malicious, is a challenge facing civilian and military operations. Commercial marine applications like shipping, tankers and bulk carriers are under threat from interference targeting their navigation and cybersecurity. Without assured positioning, these vessels can drift off-course and place the vessel, crew and cargo at risk.

Nearshore marine applications like survey, construction and piloting also require reliable positioning for uninterrupted operations in crowded waterways and RF environments. Interference mitigation and jammer direction-finding for advanced situation awareness ensure users acquire assured positioning, navigating and timing (PNT) while identifying and limiting risk from interference sources.

“Assured navigation and cybersecurity defenses are growing priorities for marine users as global threats from interference and jamming increase,” said David Russell, marine segment portfolio manager for Hexagon’s Autonomy & Positioning division. “The GAJT-410MS is an anti-jam solution protecting vessels from interference and jamming disruptions to ensure continuous operations wherever your application takes you. With GAJT, your position, navigation and timing are protected and assured.”

The GAJT-410MS is the latest iteration of proven, high-performance anti-jam products from NovAtel. It includes flexible mounting options, jammer presence and direction-finding capabilities for advanced situation awareness.

GPS-based navigation tool with multi-band GNSS provides reliable, accurate heading and position information

Garmin International Inc. has launched the MSC 10 marine satellite compass with multi-band GNSS and a fully integrated attitude and heading reference system (AHRS) for a smooth and accurate GPS-derived heading and position on the water.

“Garmin was the first to deliver a marine positioning receiver and antenna utilizing multi-band GNSS support, and we’re pleased to continue to bring this innovative technology to our customers with the MSC 10 satellite compass,” said Dan Bartel, Garmin vice president of worldwide sales. “An advanced navigation tool, the GPS-based MSC 10 won’t be impacted by magnetic interference, so even in challenging situations, you’ll know exactly where you’re headed.”

Utilizing both L1 and L5 GPS frequencies, along with multi-constellation support (GPS, Galileo, GLONASS and BeiDou), the MSC 10 provides precise positioning and heading accuracy within 2 degrees. Its 10-Hz position update rate delivers better, more detailed tracking information. By using satellite signals, it eliminates magnetic interference, which can degrade heading accuracy.

The MSC 10 is easy to install and can be used as the primary position and heading sensor across multiple systems, including autopilots. Along with heading, the MSC 10 will also deliver reliable, precise pitch, roll and heave information — even in rough seas — to a compatible Garmin chartplotter via the NMEA 2000 network. In the rare case that satellite signal is lost, it will seamlessly transition from GPS-based to a backup magnetometer-based heading.

NMEA 2000 certified, the MSC 10 is compatible with a wide range of Garmin chartplotters, including the GPSMAP 8400/8600 series, the new GPSMAP 7×3/9×3/12×3 series, and the keyed GPSMAP 10×2/12×2 series.

The MSC 10 is expected to be available this month.

Hurricane season starts June 1. Every year on that date, two Lockheed WP-3D Orion aircraft and a crew from NOAA’s Aircraft Operations Center deploy as “Hurricane Hunters,” flying directly into violent hurricanes to perform aerial weather reconnaissance.

Data gathered helps forecasters make accurate predictions on hurricane strength, direction and threats to land and life. But what is it like to fly these missions? What navigation tools and instruments are used? How do weather conditions impact these flights?

On May 27, the Institute of Navigation will host a webinar presented by Lt. Cmdr. Brian Richards, WP-3D Orion navigator and training section chief for NOAA’s Aircraft Operations Center. Deborah Lawrence, Federal Aviation Administration, will moderate. Space is limited; register early to secure a spot.

‘Take the bullseye off GPS before it’s too late!’ — PNT leaders at GWU webinar
A May 5 webinar about the GPS Backup Technology Demonstration by the U.S. Department of Transportation (DOT) provided valuable insights about the project and intended way forward for PNT efforts in the department.

It also evolved into a policy discussion with former government leaders saying establishing alternative positioning, navigation, and timing (PNT) systems would make GPS safer by “taking the bullseye off,” and that “the time is now, before it is too late.”

The webinar, titled “What Technologies Can Secure GPS?”, was hosted by the Space Policy Institute at George Washington University (GWU). A bipartisan constellation of civil PNT stars gathered to participate in the event.

Featured in the webinar were:
- introductory remarks by Robert Hampshire, chief scientist for the U.S. Department of Transportation (DOT). He has also been nominated to be DOT’s assistant secretary for research and technology.
- a presentation by Karen Van Dyke, director, Positioning, Navigation and Timing for DOT, and Andrew Hansen of DOT’s Volpe Transportation Systems Center.
- discussion of the issues by Diana Furchtgott-Roth, adjunct professor at GWU and a DOT deputy assistant secretary during the Trump administration, and Greg Winfree, director of the Texas Transportation Institute at Texas A&M University and DOT assistant secretary during the Obama administration, both of whom led civil PNT issues for the federal government during their time in office.
- Scott Pace, director of GWU’s Space Policy Institute, serving as moderator; he was executive secretary of the Space Council during the Trump administration.
Hampshire opened the event with an address that touched on Biden administration themes of “building back better,” modernizing infrastructure, reducing transportation deaths, making transportation more efficient, and preserving America’s technological leadership. All of these were linked to the need to improve PNT resiliency and reliability.

Backup tech demo did not close any doors

Van Dyke and Hansen then gave a presentation on the results of the department’s technology demonstration project.
Van Dyke pointed out that, while “GPS backup” may be a popular term, we need complementary capabilities that come into play not just when GPS is unavailable but work alongside it and provide additional capability and resilience all the time.

She also mentioned that the department is well aware there are more candidate technologies than those selected for the demonstration. Companies offering other ways of providing PNT will not be excluded from future consideration and efforts just because they were not part of the demonstration project.

Also, while the government collected the data during the demonstrations, she acknowledged that the effort was designed to “showcase the technologies in their best light.” Further study, stress testing, and evaluation will be needed for any system or technology that might be of interest to the government.

Key elements in the demos

Hansen discussed the particulars of how the technology demonstrations were conducted and some of the results. While the department evaluated 14 measures of effectiveness during the project, Hansen said that two were key — accuracy and coverage per unit of infrastructure.

All the technologies demonstrating timing showed accuracy that would be useful across a wide range of applications, he said. Positioning accuracy, though, varied from a “ones of meters to around 300 meters” depending on the technology.

Hansen said that coverage per unit of infrastructure varied exceptionally between the technologies. These included satellite systems that provide global coverage with a fixed infrastructure, and radio frequency systems with widely different coverage areas per transmitter.

He also observed that the technology demonstration project was not the end of the department’s technical inquiries. In fact, some of its results—such as eLoran performance in an underground scenario—were unexpected and are being further examined.

Transportation has some of the most stringent PNT requirements for accuracy, integrity, availability, and reliability, he said. And not all safety-critical transportation requirements may be met by market-based business models. Commercial systems lack the open standards and specifications that have made GPS so useful and widely adopted. Hansen said that the department will be working on these issues going forward, as well as performance monitoring for alternative systems.

A recurring theme throughout the webinar from all participants was that there is no single solution, no silver bullet, to achieve sufficient national PNT resilience. A systems-of-systems approach was needed. In Hansen’s words “a plurality of complementary systems” is required to ensure PNT reliability and safety, as well as efficient transportation.

Take the bullseye off GPS! — An urgent national security issue

While agreeing with the systems-of-systems approach, Greg Winfree pointed out that a first step still needs to be taken. He said that the nation has known about the need for alternate PNT since a 2001 report by DOT’s Volpe Center. Twenty years later, still no long overdue first step has been taken.

Just establishing the first alternative and complementary system, Winfree said, will make GPS and the United States much safer. “We need to take the bullseye off of GPS,” he said. GPS is so critically important to this country that it is a very attractive target for those who would do us harm. Having even one just alternative in place would make it much less of a target.

Diana Furchtgott-Roth pointed out that China, Russia, Iran and others have terrestrial systems that complement space-based PNT. About establishing alternatives, she said “The time is now, before it’s too late.”

Provisions in the United States National Space Policy provide that “[a]ny purposeful interference with or an attack upon the space systems of the United States or its allies that directly affects national rights will be met with a deliberate response at a time, place, manner, and domain of our choosing.”

Scott Pace also commented that an having an alternative to GPS will contribute to national security and improve global stability. It will “lower the pressure on us to escalate and respond” should GPS satellites be damaged, or services disrupted, he said.

Next steps

One of the questions posed at the end of the session was about actions and expected accomplishments in alternate PNT at DOT in the next 18 months. When could the first alternative system be expected?

The DOT technology demonstration report recommended that the department work next to develop standards and requirements for alternative systems. Current government employees were appropriately reluctant to say much more.

Calling upon her recent experience in government, however, Diana Furchtgott-Roth that said she believed that the department needed time to stress test technologies, develop standards and finalize requirements. Since many capable technologies were mature, some already in operation, she thought the first capability could be up and running within a year after that.

The only missing element according to Furchtgott-Roth is funding, and the focus needs to be on motivating Congress to provide it. The stage is set, she said, with all parties agreeing on the importance of resilient PNT.

She observed that it is very difficult to get the two parties in Congress to agree, and to pass legislation. Yet this has happened three times in support of establishing GPS alternatives. And PNT is such a critical capability that the entire executive branch even came together to protect it last year opposing the FCC’s decision in the Ligado Networks application.

She also related that, when she was in office, she requested $15M for the current fiscal year to do needed stress testing and standards development, but the funding did not appear in the budget.

One reason could have been questions she was asked about whether it is the government’s job to pay for an alternative to GPS, she said.

As a conservative economist her answer was and is a resounding “Yes.” The national need is beyond the business model of one company or private entity. That is something also suggested in DOT’s report on the tech demo.

Also, “enormous value and vast efficiencies” come from one entity funding such a utility, she said. “Just as the government funds national defense, it should also provide a complement to GPS.”

George Washington University’s Space Policy Institute reports a recording of the webinar will be posted on YouTube within the next week.
