Smart Antennas Introduced for Agricultural Robotics Autosteering

Published: 17 Jan 2021 by

Harxon Smart AntennasHarxon has introduced a new family of smart GNSS antennas designed for robotics applications such as autosteering in autonomous tractors and other agricultural ground vehicles. The TS112 family features three models, each with a Harxon X-Survey four-in-one multifunctional GNSS antenna that integrates 4G, Bluetooth and Wi-Fi connectivity into one compact unit, and incorporates multi-point feeding technology that delivers high phase center stability and enhanced RTK centimeter-level positioning accuracy.

The TS112 supports dual-frequency multi-constellation satellite signal tracking and delivers RTK positioning accuracy for precision agriculture equipment and machine control. It includes 4G and UHF radio modem options for flexible corrections transmission, as well as wireless Bluetooth technology for easy connectivity in the field.

The TS112SE is the most affordable solution of the three, providing standalone positioning or dual-frequency precise point positioning (PPP) with accuracy from sub-meter to centimeter level when using the SAPA precise augmentation service. Its comprehensive support and L-band augmentation service ensure solid satellite tracking without signal outage even in challenging environments. The SAPA precise augmentation service works as a reliable alternative positioning option in environments with poor LTE network coverage.

The TS112 PRO incorporates a future-ready NovAtel OEM GNSS module, offering precise positioning and advanced interference mitigation for SWaP (size, weight and power)-constrained applications. It can receive TerraStar satellite correction services for centimeter-level positioning and also supports NTRIP differential corrections via 4G for use in environments where the use of a base station is not feasible. The TS112 PRO also features NovAtel Glide smooth positioning technology for superior pass-to-pass accuracy down to 20 centimeters for applications where relative positioning is critical.

All models support Harxon’s terrain compensation algorithm that can correct deviations caused by vehicle roll and pitch on uneven grounds or slopes. The TS112 family has been designed with ruggedized IP67-rated housing, and include NMEA0183 and NMEA2000 CAN ports and RS-232 serial ports for easy connectivity.
