Stan incorporates the Trimble BX992 dual-antenna enclosure for accurate, available and reliable localization
The Stanley Robotics team has called on Trimble to equip Stan, its autonomous parking and valet robot, with accurate localization.
To achieve centimeter-level localization, Stanley Robotics needed to combine perception algorithms and intelligent management software with reliable GNSS technology.
“The robot must move fast to handle high traffic flow and precisely to park cars as densely as possible,” said Anthony Troublé, robot team manager at Stanley Robotics. The team selected the Trimble BX992 dual-antenna enclosure and two Trimble AV59 GNSS antennas.
The BX992 is installed inside the robot and the two antennas are mounted on the robot’s head with maximum separation between them. For the robot to attain centimeter-level localization, a Trimble BX992 base and a Trimble Zephyr antenna are installed at the drop-off cabins where customers leave their cars until robots move them to a more permanent location.
The Trimble BX992 base broadcasts real-time kinematic (RTK) corrections over a Wi-Fi link to the robots.
What Stan Does

With the Stan robotic valet, passengers no longer waste time looking for a free space or trying to locate their vehicle, according to Stan’s creators. After booking their parking space in just a few clicks on the Lyon Airport website, passengers drop off their vehicle in dedicated cabins and make their way to the terminals using the shuttle bus located just a few steps away.
The robot takes care of the car, parking it in the secure car park. When they return, passengers pick up their vehicle, which is waiting for them in one of the cabins.
“The service offers security, simplicity and time savings. With this new technology, parking becomes a no-fuss experience that takes only a few minutes of passengers’ time, leaving them free to travel in a relaxed state of mind,” Stanley Robotics said in a press release.
The system also constitutes a new way of arranging vehicles in a car park and makes excellent use of space since cars can be parked in dense blocks.
In addition, the robot uses two lidar scanners and four cameras. Stan relies on lidar-based simultaneous localization and mapping (SLAM) techniques to locate the robot and build a map. The lidar-based SLAM system is always running and is fused with the GNSS localization and odometry.
“The lidar is mostly critical in the cabins where the GNSS availability and reliability is not sufficient,” Troublé said. “The full integration with our localization system, especially the transition from indoor-to-outdoor when the robot enters a cabin was a challenge. We have tuned and improved our localization fusion algorithm to get the best out of each component and deliver a consistent confidence index.”
Stan is equipped with three levels of safety to ensure operational effectiveness.
First, Stanley Robotics continuously monitors the accuracy, availability and consistency of the RTK GNSS, SLAM and odometry localization signals. “If these signals are too inconsistent or if the overall confidence is too low, the robots are stopped and a site supervisor is alerted,” Troublé said.
Further, the site is monitored through lidars and cameras on the robot to prevent any collision with obstacles.
Finally, a trained Stan maintenance worker is assigned to every parking lot. These individuals wear a safety badge. Every robot is equipped with a safe-stop feature that will trigger if the operator gets within a defined proximity to the robot.
The first outdoor car park managed by robots opened to the public in 2018 at Lyon Saint-Exupéry airport. Since testing started in 2017, four Stan robots are now fully operational in the Lyon Saint-Exupéry airport car park, which can accommodate up to 500 vehicles.
Stanley Robotics announced in January 2019 that they will open 2,000 spaces at Lyon in the summer of 2020. The airport is looking to eventually expand this system to up to 6,000 spaces in total.
In 2019, Stanley Robotics signed a contract with Gatwick Airports, the first U.K. airport to use robots that valet park passengers’ cars. The Stanley Robotics team is gearing up to begin work at another airport to be announced soon.
UAV Navigation’s flight control solutions for remotely piloted air systems/unmanned aerial vehicles (RPAS/UAVs) are compatible with the Trimble UAS1 high-precision GNSS receiver. The core benefits of Trimble’s GNSS solution include centimeter-level precision and easy integration.

The light, small Trimble UAS1 receiver is less vulnerable to vibrations or temperature fluctuations, making it suitable for UAVs and RPAS. In addition, the receiver can provide real-time kinematic (RTK) positioning using a base station, enabling users to achieve higher precision for their projects.
Most UAV missions demand precision in its subsystems. The Trimble UAS1 receiver meets these requirements and includes a 336-channel high-precision GNSS engine. It tracks L1/L2 frequencies from the GPS, GLONASS, Galileo and BeiDou constellations.
The Trimble UAS1 supports OmniSTAR and Trimble CenterPoint RTX GNSS corrections, which enable precise and robust positioning without the use of a base station via a subscription service. The receiver also offers an industry-standard camera hot-shoe interface and a wide DC voltage range to work in a broad range of UAVs.
While Trimble is highly specialized in providing advanced GNSS solutions, UAV Navigation’s focus is on innovations in flight control systems. With this combined technology, current UAV/RPAS systems can now operate in more demanding environments and deliver higher precision through better navigation, UAV Navigation stated in a press release.
While often an underestimated component of a positioning and navigation system, a GNSS antenna is critical to a receiver’s success in acquiring all available GNSS signals while rejecting unintentional interference, jamming, multipath and spoofing. GNSS antennas come in as many flavors as receivers, to address the challenges posed by different market sectors, applications, environments and threats to signal integrity.
Each solution reflects a different balance among performance, cost, size and other variables. For example, antennas for handheld devices must be small and lightweight, while those for excavators and dozers can be much larger and heavier but must be able to operate for years while subjected to severe vibrations and harsh environmental conditions. Antennas for military and safety-critical applications must be especially impervious to jamming and spoofing.
Most applications, however, require antennas, like receivers, to have the smallest possible size, weight, power and cost (SWAP-C). Some applications, such as in the automotive market, must also take aesthetics into account.
We asked Javad GNSS, NovAtel, Trimble, Topcon and Harxon about their key markets and the challenges their antennas are designed to address. We also asked them to look back at the past three years and forward at the next three to discuss key innovations. Finally, they discuss technical challenges and industry trends.
See part 1 and part 2 of our GNSS receiver manufacturer overviews.

Key Markets. “The unmistakable lime-green Javad GNSS receivers and antennas are known to surveyors the world over, and we also support reference station, machine control, precise timing and any other market requiring high-performance / high-precision GNSS antennas,” said Javad Ashjaee, founder and CEO.
Specific Challenges. “A good GNSS receiver should bring in all wideband GNSS signals and reject all other unwanted signals,” Ashjaee said. “J-Shield, a robust filter in our antennas, blocks out-of-band interference — in particular, signals near the GNSS bands, such as the LightSquared signals — making the precious near-band spectrum available for other usages.”
Key Innovations. “To support our users in ever more challenging environments,” Ashjaee said, “such as denied environments where electronic warfare takes place, we have developed a new GrAnt-G2T antenna variant with even stronger J-Shield filtering: improved P1dB (the 1-dB compression point, > –30 dBm) and additional upper and lower out-of-band filtering.”
Harxon

Key Markets.Harxon is dedicated to designing and manufacturing high-precision GNSS antennas and solutions for industries such as surveying, UAVs and precision agriculture, said Wang Xiaohui, R&D manager.
Specific Challenges. “Harxon’s GNSS antennas primarily address issues related to the reliability of phase center, multi-constellation full-frequency coverage,” Xiaohui said, “tracing unstable satellite signals at low elevations, multipath signal interference, and how to integrate high-precision GNSS antennas and mobile communication antennas into a single design.”
Key Innovations. Over the past three years, Harxon has made “great breakthroughs” in GNSS antenna innovation, Xiaohui said. First, it greatly reduced the size and weight of choke ring antennas. As an example, Xiaohui cited the company’s mini choke ring antenna HX-CGX611A. Second, it optimized accuracy to the millimeter level and expanded to full frequency its quadrifilar helix antenna, such as with the D-Helix antenna. Third, Harxon upgraded the surveying industry to 4G communication by developing a four-in-one antenna that supports multi-constellation with full frequencies and integrates GNSS antennas, Bluetooth and 4G modules with high compatibility and outstanding performance, Xiaohui said, such as with the HX-CSX100. “For the next three years, Harxon will continue its research and investment in antenna technology breakthroughs, especially with regard to further miniaturization and improved performance.”
Technical Challenges. “The first interesting challenge is how to guarantee the performance of the antenna while miniaturizing it per our customers’ demands,” Xiaohui said. The second is reducing the size and weight of antennas with anti-multipath technology, “so as to boost the applications of high-precision positioning GNSS technology.”
Trimble

Key Markets. “Trimble’s core technologies in positioning, modeling, connectivity and data analytics enable customers to improve productivity, quality, safety and sustainability,” said Stuart Riley, vice president, GNSS Technology. “From purpose-built products to enterprise lifecycle solutions, Trimble software, hardware and services are transforming industries such as agriculture, construction, geospatial, transportation and logistics, rail, forestry, utilities and autonomous applications.”
Specific Challenges. Each application has different requirements, Riley said. “For applications that require the highest position accuracy, the stability of the phase center, multipath mitigation, and the unit-to-unit production consistency are critical,” he said. Some customers require high performance in challenging environments — such as the high vibration experienced on construction equipment — while others require smaller, lower-cost antennas and can tolerate a slight reduction in accuracy. “The antenna is typically a combination of a passive antenna element with an active low noise amplifier (LNA),” he said. “The LNA needs to be carefully designed to remain linear in the presence of in-band jamming while rejecting out-of-band signals. There are size and cost trade-off challenges to the filter roll-off at the band edge that need to be managed.”
Key Innovations. For high-precision applications, Trimble first released the Zephyr series of antennas in the late 1990s. “It provides excellent phase center stability and unit-to-unit production repeatability, and has exceptional multipath mitigation performance, which is enhanced in the geodetic version,” Riley said. Since first introducing the antenna, Trimble has added support for additional GNSS systems and RF bands (L1/E1, L2, L5/E5 and L6/E6), transitioned to a RoHS-compliant manufacturing process, improved the LNA performance, developed rugged versions for construction vehicle mounting, and produced a smaller version used in the Trimble R10, R12 and SPS986 GNSS receivers.
“More recently,” Riley said, “we developed a lower-cost high-performance antenna for the Trimble Catalyst software-defined GNSS receiver for Android phones and tablets, as well as an antenna in the Nav-900 guidance controller for agriculture that implements a metamaterial design. Looking forward, we expect to continue to innovate by providing antennas that meet the needs of the different markets we serve. Each application has unique requirements, which require us to balance the cost, performance and size to develop the appropriately optimized product. Enhancements will include novel antenna architectures, production technique improvements, and careful material selection.”
Technical Challenges. Trimble users have a wide variety of requirements, Riley said. “The challenges come in balancing the seemingly conflicting needs for performance, size, weight and cost. Because Trimble focuses on specific user segments, we can provide antenna solutions that are the best fit for the various applications. For example, an antenna in a handheld device must be small and lightweight; however, on a construction machine, durability takes precedence over size and weight.”
Topcon Positioning Group

Key Markets.Topcon Positioning Group is a leading designer, manufacturer and distributor of precision measurement and workflow solutions for the global construction, geospatial and agricultural markets, according to Alok Srivastava, director, product management. “By integrating high-precision measurement technology, software, services and data, Topcon has a vision to improve productivity to meet global demand for sustainable infrastructure and agriculture,” Srivastava said.
Specific Challenges. The physical challenges when designing an antenna for geomatics applications have been multipath and interference mitigation, Srivastava explained. “Topcon has an advanced research and development team that focuses solely on antenna designs. The team dedicates its efforts to providing state-of-the-art antennas for all positioning needs.”
Key Innovations. “Topcon was very early in realizing the growing needs for radio spectrum and the challenges it may bring to GNSS technology,” Srivastava said. “It has innovated and used filters to mitigate interference from Japan LTE signals for a long time.”
Topcon’s antenna team is “among the most innovative in the industry,” Srivastava said, and “has brought many unique designs of antennas over the years. The antenna is a key element of an integrated receiver in dictating the design of the whole receiver.” With the release of the Sokkia GCX2 receiver, he explained, his company introduced to the industry the integration of a helical antenna into a high-performing integrated receiver.
Its infrastructure antennas, the CR-G5 and PN-A5, are available with options including cavity filter technology. “The cavity filter has the superior ability to minimize near-band interference,” Srivastava said. Topcon’s antenna farm at the Concordia test site in Italy contains an absolute calibration robot, a large format antenna (BigAnt) for a high-quality geodetic ground station, and patented technology for controlled testing of GNSS technology in artificial obstructions.
“Vibration mitigation is the key when an antenna is mounted to a piece of machinery,” Srivastava said. “Topcon antennas are an integral component of our Quartz Lock Loop (QLL) technology for robust GNSS operation in high-vibration environments.”
Technical Challenges. The importance of antennas can be underestimated, Srivastava pointed out, especially with rapidly growing interest in GNSS technology in consumer applications. “The antenna is one of the most critical technologies when it comes to reliable and robust GNSS positioning. Designers and manufacturers of antenna technology with years of experience understand the seriousness of this task, and are fully equipped to deliver results without compromising quality and performance.”
NovAtel

Key Markets. Key antenna markets for Hexagon’s Autonomy & Positioning division are split into three areas, according to Dean Foster, director of hardware engineering. His area includes the company’s anti-jamming antenna technology (GAJT) and robust SWAP-C antennas. The other two are precision and SMART antennas for agriculture, mining, survey and autonomous vehicles (Vexxis, SMART7, and GNSS 1500), and reference GNSS antennas (GNSS750 and ANT-C2GA).
Specific Challenges.NovAtel’s antennas address three main challenges. First, jamming and interference, whether intentional or unintentional, are becoming increasingly commonplace and seriously impact GNSS reception. “These issues are addressed by our GAJT product line of high-precision anti-jamming antennas, which can mitigate multiple jammers simultaneously,” Foster said. Second, “the stability and precision of the antenna’s phase center is critical to deliver robust and precise GNSS position even in challenging environments, which is addressed by our Vexxis GNSS-800 antennas.” Finally, more frequent use of GNSS in environments with reflection issues is making multipath rejection critical. “The entire line of NovAtel antennas, including Vexxis, SMART and GAJT, ensures use of the most direct signals.”
Key Innovations. Driverless vehicles require sub-meter-level positioning for lane-level resolution. “Multi-constellation/multi-frequency GNSS with protection limits and correction services are necessary to move forward safely,” Foster said. “This technology does not work with the smallest size, single-frequency, narrow-band antennas that cars currently utilize, so we’re building on our deep experience and knowledge to develop production-grade automotive antenna technologies.” An emerging requirement is reducing size, weight, power and cost (SWAP-C). “In the defense market, we first offered jamming and interference mitigation with the GAJT-710, which progressed to the GAJT-AE, and most recently we launched the GAJT-410.”
Technical Challenges. All markets want the smallest, most robust and cost-effective antenna to meet their needs, Foster said, adding that NovAtel is helping customers work through how to select, place and integrate antennas into their platforms to address real-world problems.
The prevalence of intentional and unintentional GNSS interference has sparked quick evolution in antenna technology, including the emergence of breakthrough technology in 2019 and new advancements in development, said Imtiaz Bahadur, product line manager.
Specifically, the drive to advance antenna technology is due to “an increased demand for broader coverage, stringent industry compliance, and a need for robust capabilities.”
Key Innovations. Among recent innovations in antenna technology, Bahadur cited GPS antennas with support for dual-frequency multi-constellation compliance with Global Aircraft Traffic Management (GATM) mandates to enable military aircraft to operate in controlled airspace, and antennas that offer broader band coverage.
In 2019, Cobham introduced the 20-2041 Fixed Reception Pattern Array (FRPA) GPS antenna, which addresses all three of these priorities, said Darren Windust, product manager – air. The L1/L2 dual-frequency GPS antenna is certified to both ETSO-C190 and MSO-C144. “In conjunction with a certified receiver, the 20-2041 offers a single solution to comply with GATM regulations to access controlled airspace and undertake GPS precision approach and landings, in a standard 3.5-inch form factor.”
Technical Challenges. “It’s clear that moving from one GPS signal to eight signals from four constellations in support of performance-based navigation is going to be the next major disruptor because of the significantly expanded signal power and highly efficient design,” Bahadur said. The quest to make antennas smaller also continues. “Today, there are physical limitations on how far one can miniaturize the antenna while ensuring sufficient gain is received. Research and development efforts are underway to build ‘smart antenna’ concepts for the future. Moving into the next few years, robust antenna capabilities will arrive in smaller, more efficient form factors.”
Top receiver manufacturers discuss what’s on the horizon for GNSS receivers. The companies reveal recent and upcoming innovations, how to combat spoofing and jamming, fusing GNSS with other sensors, and the impact of increasing accuracy both for professional surveyors and consumers.
With regard to jamming and spoofing, the preferred approach is a combination of monitoring, detection and filtering. However, shielding, the use of IMUs and other third-party sensors, and advances in processing algorithms also help mitigate interference. In a few years, hopefully, encrypted or “watermarked” signals will substantially reduce this problem.
IMUs and other sensors are now routinely integrated with GNSS receivers, with their outputs fused. This trend is largely propelled on the demand side by the needs of the emerging market for autonomous vehicles and on the supply side by smaller, cheaper and more accurate IMUs and lidar scanners. Meanwhile, developments in algorithms have improved the modeling of errors to correct for the inherent tendency of IMUs to drift. Additionally, digital cameras, lidar and other industry-specific sensors are increasingly common, especially for collision avoidance in human-machine interactions.
In surveying, the use of all constellations and frequencies, as they become available, is an industry trend. Costs will continue to drop as the growth in the adoption of GNSS solutions enables manufacturers to take greater advantage of economies of scale. Precise point positioning (PPP), which benefits greatly from the growth in GNSS constellations, is now giving real-time kinematic (RTK) positioning a run for its money. Available applications enable Android mobile devices to achieve centimeter accuracy, while innovations continue in core positioning algorithms.
In the world of mobile consumer devices, dual-frequency, multi-constellation GNSS chipsets are increasingly prevalent. As increased accuracy fuels expectations for even higher accuracy, precision positioning may become the norm in the consumer space, and new applications for these devices may emerge. Already, crowdsourcing the monitoring of both GNSS signals and interference helps improve accuracy for everyone, in a positive feedback loop.
Other notable trends include the introduction and expansion of 5G data networks, the increased use of satellite-based correction services, and continued efforts to develop precise positioning for indoor areas. (See part 2 of this feature here.)
Topcon
Jamming and Spoofing. “We continue to develop and deploy patented technology to detect spoofing,” said Alok Srivastava, director, product management. “We already have cutting edge GNSS antenna technology to provide stellar support for interference rejection and filtering.” All Topcon end products have this advanced antenna and filtering technology.
Sensor Fusion. “Topcon has been using inertial systems for decades for a variety of positioning applications — such as machine control, mobile mapping, and agriculture,” said Srivastava. “In recent years, advancements in IMU technology have progressed to where the size and cost of these sensors are at levels to be utilized at a larger scale. For example, the recently released Topcon HiPer VR takes advantage of inertial technology to improve productivity in real time with our Topcon Integrated Leveling Technology (TILT), which compensates for mis-leveled field measurements out of plumb by as much as 15 degrees.”
Surveying. Topcon continues to invest in its core positioning algorithms to innovate such features as quartz lock loop, advanced multi-engine platform, and VHD heading technology into its positioning engines, Srivastava said. “We also produce solutions such as our Millimeter GPS and Hybrid Positioning innovations, which are designed around improving accuracy, higher reliability, and greater flexibility by converging positioning technologies.”
Consumer Devices. “GNSS in consumer devices and other commercial systems is used to aid other positioning sensors,” Srivastava said. “So, it may not be in the best of interest to offer that level of accuracy from GNSS alone.”
Other Challenges. Precise indoor positioning is a requirement of the vertical construction industry. “Topcon’s combined optical instrument takes a unique approach to solve that problem by integrating a compact laser scanner with a fully featured robotic total station,” Srivastava said.

Jamming and Spoofing.CHCNav is currently taking a twofold approach to GNSS interference, said François Martin, vice general manager, International Division. “As a GNSS system integrator, we focus our design around strong electromagnetic shielding and sealed isolation chambers.” Additionally, he pointed out, the advanced filtering of GNSS signals and an antenna patch produce optimal interference mitigation.
Sensor Fusion. Integrating interference-free, high-dynamic IMUs instead of MEMS has brought the full benefits of tilt compensation to users, Martin said. The latest development in algorithms dramatically obviated the need for the annoying process of initializing GNSS IMU receivers and boosted the availability of GNSS RTK in demanding environments.
Surveying. The fast adoption of GNSS solutions by large user segments has reduced costs by enabling a sizable manufacturing economy of scale, Martin pointed out. “Tighter combination of embedded technologies such as GNSS and connectivity modules are sustaining that cost reduction process.”
Consumer Devices. “The emergence of dual frequency multi-constellation GNSS chipsets supports the development of untapped user segments, but the position accuracy repeatability remains an issue,” Martin said. “The integration of GNSS chipset and high-performance helical antennas, as precision add-on modules, onto rugged Android cell phone and tablets is creating a prosumer-grade centimeter to decimeter accuracy answering to a wide range of mobile workforce applications.”
Other Challenges. A growing number of positioning and navigation applications require the fusion of technologies to increase productivity, Martin said. “The integration of advanced tightly integrated positioning algorithms, scanners, IMUs, HDR cameras, IoT and cloud-based connected solutions are a clear trend.” However, their adoption by a large user base remains limited by their current price point.

Jamming and Spoofing. “Recent developments in receiver-antenna combinations maximize the benefits of anti-jamming techniques,” said Gustavo Lopez, market access manager. Third party sensors, such as IMUs, also help mitigate interference, he pointed out. “Septentrio’s advanced receiver technology such as AIM+, a standard feature on all the company’s products, bring not only real time monitoring but also jamming/spoofing mitigation. Galileo and GPS have clear roadmaps bringing signal authentication in order to avoid spoofing.”
Sensor Fusion. Smaller IMUs with higher grade performance now on the market are enabling new use cases in autonomous applications, said Lopez. Other important elements are a new generation of compact high-performance sensors and the growing importance of multi-sensor technology “to provide even higher levels of positioning integrity.” He cited Septentrio’s AsteRx-i family of products as an example of GNSS/INS integrated solutions.
Surveying. As an example of Septentrio’s survey-specific products, which “continuously benefit from advanced developments being rolled out in our platform,” Lopez cited the Altus NR3.
Consumer Devices. The increasing positioning accuracy of cell phones, Lopez pointed out, “has spurred innovations such as PPP and the use of mobile phone measurements,” as well as “other purposes, such as interference detection and crowdsourcing.”
Other Challenges. “Sensor fusion is a key element in positioning and orientation,” Lopez said. “Easy integration is a key element in this trend. Also, integrity in error reporting and positioning will be required as well as reliable raw measurements which can be integrated with other sensors. This drives the requirement for receivers capable of running customer proprietary software. Another important element will also be the possibility of running positioning algorithms on a third-party processor.”

Hemisphere GNSS
Jamming and Spoofing. “Hemisphere’s new Lyra II ASIC platform used in our Phantom and Vega series positioning and heading boards,” said Miles Ware, director of marketing, “introduces new technology and filtering methods to identify and mitigate known and unknown interference sources that typically have an adverse effect on GNSS performance.”
Sensor Fusion. “Advancements in IMU integration and sensor fusion,” Ware said, “will continue to be a key focus for Hemisphere to support the growth and adoption of the expanding autonomous vehicle and application marketplace. The positioning and heading technology offered in our Vega 28 will be a core component for autonomous marine, machine control, and agriculture solutions for new and emerging markets.”
Surveying. “Access to modern and future signals like BeiDou Phase III, ALTBOC and BS-ACEBOC significantly enhance GNSS accuracy, especially in challenging environments where satellite visibility is compromised by the topography and or the structures present,” Ware pointed out. “Survey solutions that can not only track but also use all the available GNSS measurements in their RTK solution will have a substantial advantage in the market.”
Consumer Devices. “As mobile phones and consumer devices continue to adopt hardware designs that can access the latest GNSS signals,” Ware said, “the opportunities for solutions where high precision measurement engines can be hosted within mobile devices opens up a new realm of solutions that can leverage the high accuracy positioning performance found in Hemisphere technology and products. We see this as a very exciting and emerging area.”
Other Challenges. Ware pointed to “leveraging GNSS technology to further support environmentally friendly transportation solutions and sustainable agriculture,” for which GNSS continues to be an integral component.

Sensor Fusion. “We are implementing GNSS with different level IMUs, including low-cost and high-end, targeting automotive, intelligent driving, and robot application scenarios,” said Gao Jingbo, marketing director. “The algorithm can also integrate with the already-existing sensors on the platform, such as IMUs, cameras and odometers. The solution can be done on the GNSS side, with high information synchronization accuracy, or processed on the platform.”
Surveying. Products with Unicore boards inside can provide centimeter- to millimeter-level positioning accuracy, said Jingbo. “Unicore’s high-precision boards and modules can track all frequencies of all satellite systems. The UGypsophila RTK technology can make the most of the observation data of all frequencies in all systems even without the observations of the base station in the RTK solution, thus greatly improving the usability, reliability and accuracy of RTK.” The company is now also working to reduce the dimensions and cost of its products, Jingbo pointed out. “With Unicore’s single GNSS SoC on board, the UB4B0M and UM4B0 modules are making affordable high-end high precision surveying possible.”
Consumer Devices. Algorithms and hardware are ready now to implement PPP+RTK in cell phones, Jingbo said, and this increase in positioning accuracy will enable many more applications. “We have rich experience in high precision GNSS, but the antenna might be a challenge. Our new generation 22 nm GNSS SoC features low power consumption and support of sensor fusion. Additionally, true point technology by Rx-Networks (also a BDStar company) can provide sub-meter data service, which also enables users to access centimeter-level accuracy location data through their mobile phones and wearable technologies, without increasing the demand for processing power.”

Trimble
Jamming and Spoofing. “Trimble’s latest GNSS receivers leverage our seventh-generation Maxwell technology, which implements hardware- and software-based techniques to detect and mitigate spoofing,” said Stuart Riley, vice president, GNSS Technology. “In addition, Trimble continues to improve the robustness of our GNSS receivers with advances in processing algorithms and hardware enhancements such as the integration of inertial technology.”
Sensor Fusion. “For many years, IMUs have been widely used in Trimble agriculture and Applanix products,” Riley said. “Over the past few years, we’ve created a new line of lower-cost inertially integrated board-level GNSS receivers. We have also integrated inertial components into survey and construction products, including tilt compensation in the Trimble R10, R12 and SPS986 receivers. Trimble also combines its GNSS solutions with optical, laser, lidar and other sensors.”
Surveying. Trimble’s GNSS products, Riley pointed out, range from GIS handhelds to high-performance mobile mapping systems.
Consumer Devices. “The Trimble Catalyst system uses Android-based smartphones or tablets to run an application that includes a software-defined GNSS receiver,” Riley said. “The recently introduced SiteVision system builds on this ecosystem and integrates Google’s ARCore platform with precision GNSS to provide an augmented reality solution for a variety of professional applications.”
Other Challenges. To address signal masking and multipath, Trimble has “continued to improve performance in difficult environments with products such as the Trimble R12 receiver, which provides sophisticated multipath mitigation and an advanced precision processing engine.” Riley said, “Trimble’s RTX Correction Services, delivered via satellite, enable users to achieve RTK speed and accuracy nearly anywhere on the planet without the need for local reference stations.”

Jamming and Spoofing. “The RF environment is at best crowded and at worst hostile,” said Sandy Kennedy, vice president of innovation, Hexagon’s Positioning Intelligence division. “The NovAtel OEM7 generation of receivers was launched in 2016, with interference detection and mitigation as key features on every variant. Protecting authenticity, availability, and precision for multifrequency measurements is the challenge going forward — in all segments of the system: constellation management and SIS, antenna, receiver design and processing in FW/SW.”
Sensor Fusion. In the last three years, Kennedy pointed out, IMU manufacturers have made significant improvements in the performance offered in smaller, cheaper IMUs. “At the same time, new methods to improve error modelling (to control positioning errors) have been added to the NovAtel SPAN product line, especially in SPAN Land profile. Extended GNSS outages are easily handled now.”
Surveying. “PPP has become a strong competitor to RTK, as convergence times have decreased, and this will continue in service offerings like Terrastar-X from NovAtel,” Kennedy said.
Consumer Devices. The devices, Kennedy said, offer “the tantalizing promise of quality measurements from a common utility device with huge computing horsepower and data connectivity built in! It’s fun to watch, and we shall see if accuracy is truly addictive enough to fuel development for general use of precision positioning.”
Other Challenges. “In the past 20 years, users have moved from awe and wonder that centimeter-level positioning is possible — to utter contempt when it is not,” Kennedy said. “This will continue, with an added requirement of integrity and functional safety. Continuously available positioning within a usable protection level is a requirement for autonomous vehicles.”
