Overview

The Stonex S900A-TH GNSS receiver is equipped with a high performance GNSS board with 800 channels that is capable of supporting multiple satellite constellations: GPS, GLONASS, BeiDou, Galileo, QZSS and IRNSS, as well as L-Band corrections.

Through the 4G GSM modem, a fast internet connection is guaranteed for the reception of correction data and the management of the maps in the background. In the amazingly compact structure, the Bluetooth and Wi-Fi modules allow always reliable data flow to the controller, and the integrated TX/RX UHF radio with selectable frequencies, make S900A-TH the perfect system for a GNSS Base + Rover.

The Stonex S900A-TH integrates an E-Bubble sensor that allows for measurement of difficult points even when the pole is not level. You can calculate the correct coordinate of a point by measuring from 3 different positions. The S900A-TH is also equipped with the optional IMU technology. Fast initialization, up to 60° inclination and the correct coordinates of a point with a simple click.
