The AsteRx-m3 Sx OEM board dual-antenna receiver combines Septentrio’s latest core GNSS technology with the SECORX-S sub-decimeter correction service to enable plug-and-play positioning. High-accuracy positioning is available directly out of the box, GNSS corrections automatically streamed to the receiver. This significantly simplifies the set-up process and eliminates the need for corrections service subscription and maintenance. Corrections are delivered via internet or L-band satellites, ensuring sub-decimeter service even in remote locations where there is no easy internet access.

GNSS antenna
Smart antenna for 5G timing
Photo: Tallysman
The new TW5382 smart GNSS antenna is designed for high-accuracy 5G timing. The TW5382 is a multi-band, multi-constellation 5G smart GNSS antenna/receiver that provides 5 ns (1-sigma, clear sky view) timing accuracy. It consists of two components: a Tallysman GNSS Accutenna technology antenna and a professional-grade GNSS timing receiver module. Accutenna supports the full bandwidth of the TW5382 receiver, strong multipath mitigation and deep filtering in a compact IP69K enclosure. These features enable the antenna to provide a strong, pure, in-band, right-hand circular polarized signal to the receiver. The TW5382’s professional-grade multi-constellation and multi-signal timing receiver tracks GPS/QZSS (L1/L2), GLONASS (G1/G2), Galileo (E1/E5b), and BeiDou (B1/B2) signals.

IoT GNSS module
For quick integration of precise positioning
Photo: Swift Navigation
The new Precision GNSS Module (PGM) is designed to offer fast evaluation and a quick path to production for those requiring a precise positioning solution. It is available in a simple-to-use, industry-standard mPCIe (mini peripheral component interconnect express) format and is designed specifically for Swift’s Starling positioning engine running on a host application processor to deliver real-time precision navigation. The PGM utilizes STMicroelectronics’ TeseoV chipset in Quectel’s multi-constellation, dual-band LG69T-AP receiver to create an affordable, easy-to-use solution for customers building industrial, last-mile and internet of things (IoT) platforms. This solution operates with the highest accuracy when used with Swift’s Skylark positioning service.

Inertial navigation system
Success in ultra-high-altitude flight simulation
Photo: Systron Donner
CAST Navigation tested Emcore’s SDN500 inertial navigation system (INS) in an ultra-high-altitude flight simulation and achieved success. The test required simulating performance at an altitude of more than 24,000 meters and velocities over 600 m/s. Only a few aircraft in the world have such capabilities, including the SR-71 Blackbird, but it is not practical to participate in a test flight on the SR-71. Simulating the SDN500 INS test flight to specific customer profiles on a CAST system is straightforward and cost-effective. Emcore relies on GNSS/INS simulators for hardware-in-the-loop testing to verify the expected performance of algorithms. Emcore sought to validate the velocity and altitude limits of a new GNSS receiver along with the algorithm performance in a tactical-grade SDN500 system.

The Agras T20 drone can conduct autonomous operations over a variety of terrains, such as broad-acre farmlands, terraces and orchards. As a comprehensive spraying system, the T20 allows users to easily set flight and operation parameters. With a built-in real-time kinematic (RTK) centimeter-level positioning system and RTK dongles, centimeter-level waypoint recording is enabled, strengthening operations and ensuring precision spraying.The T20 is equipped with eight nozzles and high-volume pumps that can spray at a rate of up to 6 liters per minute. A highly optimized wind field produces droplets of the correct size and consistency. The T20 is also equipped with a new four-channel electromagnetic flow meter, which monitors and controls four hoses individually, ensuring an efficient flow rate for each nozzle.

SURVEYING AND MAPPING
Virtual base station
New feature in post-processing software
Photo: SBG Systems
A new virtual base station (VBS) feature is available in Qinertia, GNSS and inertial navigation system (INS) post-processing software. Trajectory and orientation are greatly improved by processing inertial data and raw GNSS observables in forward and backward directions. The VBS computes a virtual network around a project in which position accuracy is maximized, homogeneous and robust, such as a PPK short baseline. Once surveyors collect data, Qinertia chooses the most relevant reference stations, builds a virtual network and brings the project to centimeter-level accuracy with no convergence effects, even in urban areas.
