Tersus Develops High-Precision GNSS Positioning Solutions for Unmanned Systems

Published: 04 Jan 2017

Tersus GNSS, a provider of real-time high-precision GNSS positioning solutions for unmanned systems, has partnered with Unmanned Systems Technology (“UST”) to demonstrate their expertise in this field. The ‘Gold’ profile showcases how their centimeter-level accuracy GNSS technologies can be used to empower unmanned vehicles and robotics with greater accuracy, in applications such as surveying, mapping, precision agriculture, and unmanned aerial vehicles (UAVs).

Precis-BX316 GNSS RTK BoardThe Precis-BX316 is a multi-GNSS dual antenna RTK board that provides real-time, precise positioning and heading capabilities for unmanned vehicles. Supporting GPS L1 & L2, BDS B1 & B2 and GLONASS G1 & G2, as well as GPS heading mode, it features 192 channels and a 20Hz maximum update rate. Weighing just 33 grams and easily interfaced with autopilots such as Pixhawk and with other host devices, the Precis-BX316 is ideal for integration into UAVs.

The Precis-BX305 is a multi-GNSS dual antenna RTK board that supports GPS L1 & L2, BDS B1 & B3 and GLONASS G1. It features 192 channels and a 20Hz maximum update rate, and supports logging of raw observation data.

The Precis-BX305 kit provides everything needed to quickly set up a low-power radio link of up to 100mW, allowing users to experience the functionality of the Precis-BX305 over distances of up to 1km. Radio modems and antennas are available in 915Mhz (US) and 433Mhz (European) frequencies.

Precis-TX204 GNSS ReceiverThe Precis-TX204 is a lightweight and rugged multi-GNSS receiver designed to support fieldwork in demanding environments. The built-in battery provides up to 10 hours of operation and internal SD card storage enables up to 16GB of data logging. Supporting GPS L1 & L2 and BDS B1 & B2, with GSM/GPRS/EDGE connectivity, the Precis-TX204 also features 128 channels and a 1Hz update rate.

The AS3703 is a miniature GNSS antenna weighing less than 100 grams that has been designed for UAVs and other vehicle-mounted positioning applications. Capable of receiving GPS L1 & L2, GLONASS G1 & G2 and Beidou B1, B2 & B3 frequencies, the AS3703 provides 360° azimuth coverage.

AX3702 GNSS ANTENNAThe AX3702 is a lightning-protected, sealed water- and dust-proof antenna designed for long-term outdoor surveying applications. It receives GPS L1 & L2, GLONASS L1 & L2 and BDS B1, B2 & B3 frequencies, with 360° azimuth coverage and a peak gain of 5.5 dBi. The antenna can be configured for GPS-only or dual constellation applications, and features state-of-the-art multi-path rejection technology to eliminate multi-path influenced measurement error.

The DL207 is an external data logger designed to provide greater storage capabilities for the Precis-BX305 and Precis-BX316 boards. It stores observation data on MicroSD cards and features a 115200bps serial connection as well as a Mini-USB flash disk mode. Logged binary data can be converted to RINEX format using the Tersus GNSS Center configuration software.
