A roundup of recent products in the GNSS and inertial positioning industry from the August 2022 issue of GPS World magazine.
The Trimble BD9250 dual-frequency receiver module supports Trimble RTX correction services and is designed to deliver high-accuracy positioning for high-volume, autonomous-ready applications in agriculture, construction, robotics and logistics. The compact receiver has an industry-standard form factor and pinout, allowing for easy system integration and configuration. Equipped with Trimble’s advanced ProPoint positioning engine, the BD9250 delivers robust and accurate positioning. It is compatible with Trimble RTX correction services or real-time kinematic (RTK) and supports GPS, Galileo, GLONASS and BeiDou as well as QZSS and NavIC. Support for the Indian NavIC S-Band signal is also available.
For construction, mining and machine control
The AsteRx-U3 ruggedized GNSS receiver is the successor to the AsteRx-U for construction, mining and other machine control applications. It combines a triple-band precise positioning GNSS core with extended wireless communication features including Wi-Fi, UHF and 4G LTE, making it easy to fit it into any control system. The AsteRx-U3 offers low latency of under 10 msec with a high data rate, which allows machines to work rapidly and accurately. An IP68-rated housing, with fixing brackets and robust M12 connectors, enables quick installation.
The M20071 integrated GNSS receiver module, measuring 9 x 9 x 1.8 mm, incorporates the MediaTek AG3335MN flash chip. The receiver tracks four GNSS constellations concurrently (GPS + Galileo + GLONASS + BeiDou). The 1.8-volt system power supply provides outstanding low power consumption. Its multipath algorithms improve position accuracy in inner-city environments. The onboard low noise amplifier provides good performance in weak signal environments such as wearable devices.

For guided weapons and other small applications
The Strategic Anti-jam Beamforming Receiver – M-Code (SABR-M) enables precise geolocation and strike capabilities in highly contested battlespaces. It integrates receiver technology with advanced antenna electronics in a small, hardened package designed to meet challenging performance requirements. It delivers accurate position, velocity, altitude and timing data, as well as strong protection against GPS signal jamming and spoofing. At 4.5 x 6 x 1 inches, the SABR-M meets size, weight, power, cost (SWaP-C) and thermal requirements for space-constrained military applications. It uses advanced beamforming technology to improve GPS signal reception and counter threat signals.
The GPS Resilient Kit (GRK) is a cybersecurity device that comes with two antennas for monitoring and protecting time-critical infrastructures. It can be integrated with any GNSS receiver, either as a retrofit or in greenfield deployment. The GRK features a proprietary interference filtering algorithm for maximum protection, up to 40-dB attenuation of jamming signals with the premium option. It requires minimal power consumption while providing cloud-based monitoring with real-time reporting of jamming attacks. It protects GPS L1 (C/A code) with a latency of 100 ns ±15 ns (fixed).

GBaaS enables providers to combat PNT cyberattacks
GNSS-backup-as-a-service (GBaaS) enables service providers to help operators safeguard services that rely on positioning, navigation and timing (PNT). In-network timing based on network time protocols (NTP) and precision time protocols (PTP) are also increasingly vulnerable to cyber threats. GBaas is based on ADVA’s aPNT+ platform, which leverages a suite of technologies, including multi-band GNSS receivers and management software based on artificial intelligence and machine-learning. Service providers can offer ADVA’s aPNT+ protection as a subscription-based service as part of their service-level agreements.
Can be used as base station or rover
The i73+ pocket-sized receiver is a powerful and versatile receiver with an integrated UHF modem that delivers survey-grade accuracy in all jobsite configurations. It has 624 GNSS channels and the latest iStar technology and can be operated as either a base station or a rover. The i73+ is a highly productive NTRIP rover when used with a handheld controller or tablet and connected to a GNSS RTK network via CHCNAV LandStar field software. The receiver takes advantage of GPS, GLONASS, Galileo and BeiDou, in particular the latest BeiDou 3 signal, to provide robust data quality at all times.
The Geode GNS3 GNSS receiver allows users to collect real-time GNSS data with sub-meter, sub-foot and decimeter accuracy options. With a scalable accuracy platform, users can purchase what they need now, while having the option to increase accuracy in the future. It offers sub-meter accuracy with a single-frequency antenna, while its multi-frequency antenna supports all constellations on L1, L2 and L5. Atlas L-band corrections allow the Geode to be used in water utility locating, agriculture and irrigation mapping, as well as mapping projects in remote locations where other correction services are not available. The Geode GNS3 can be used with Windows, Android, iPhone and iPad devices.
Improved colorization to contextualize point clouds
The ZEB Vision is a camera accessory for the ZEB Horizon system that can be used to capture 360° panoramic photography in 4K definition for point cloud colorization. Data is captured as the user walks through the area of interest. The ZEB Vision uses GeoSLAM’s SLAM algorithm to automatically and accurately position panoramic photos on a point cloud for an interactive viewing experience. The ZEB Vision attaches easily to the ZEB Horizon. The 4K resolution increases feature definition of objects within the point cloud, allowing for a new perspective on data by navigating within a virtual representation of an environment. This means industries such as architecture, construction and facilities can add real-world context to point clouds for the creation of CAD/BIM models.
The Leica Chiroptera-5 is a high-performance airborne bathymetric lidar sensor for coastal and inland water surveys. It combines airborne bathymetric and topographic lidar sensors with a four-band camera to collect seamless data from the seabed to land. Compared to previous models, the Chiroptera-5 provides 40% higher point density, a 20% increase in water-depth penetration, and improved topographic sensitivity for generating more detailed hydrographic maps. Its high-resolution lidar data supports nautical charting, coastal infrastructure planning, environmental monitoring and landslide and erosion risk assessments.
For field data capture and collaboration
The Clirio application combines mobile lidar 3D scanning with smart remote collaboration tools to offer teams an end-to-end 3D solution to capture, organize, share and problem-solve. This is all based on real-time field observations and data, whether team members are on site or a continent away. Clirio is a set of mobile, web and VR/AR apps for instantly capturing, sharing, reviewing and resolving worksite field observations. At a field site, Clirio users collect notes, photos and 3D scans (using the laser scanner built into a new iPad Pro or iPhone Pro). These field observations are automatically geo-referenced within the map-based workspace and synced to a secure cloud workspace. An intuitive interface allows colleagues, managers, partners, or stakeholders to sort, review, compare, and act on field observations.
Designed to meet scooter parking challenges
The Visual Parking System (VPS) by Bird is designed to keep track of scooter parking in a scalable, efficient and vandalism-immune way that requires zero infrastructure within a community. Powered by Google’s ARCore Geospatial API, VPS enables scooter parking with pinpoint accuracy. When parking a scooter, riders will be prompted to take a quick scan of their surroundings. The system seamlessly compares a rider’s images against Google’s data and Street View images in real time to produce the best available parking solution. Stationary objects such as buildings and signs are used as reference points, while more dynamic objects such as people and vehicles are disregarded. The near-instantaneous process results in a precise, centimeter-level geolocation that enables Bird VPS to detect and prevent improper parking with extreme accuracy, helping ensure Bird vehicles are only left in approved areas.
