Stonex S900 A series


The Stonex S900A GNSS receiver series is equipped with a high performance GNSS board with 800 channels. This allows the sensor to receive all current satellites: GPS, GLONASS, BEIDOU, GALILEO, QZSS and IRNSS, including L-band correction. The Stonex S900A automatically selects the best combination of GNSS signals. Thanks to the aRTK function and the Atlas® correction service, the receiver can also work in particularly difficult areas. Atlas® gives the precise positioning centimeters around the world and delivers centimeter correction data worldwide via L-band communications satellites and over the Internet.

A fast Internet connection for receiving correction data is guaranteed via the 4G GSM modem. High-quality Bluetooth and Wi-Fi modules ensure an always reliable flow of data to the controller. The integrated TX / RX-UHF radio with selectable frequencies makes the S900A the perfect system for a GNSS base station or a rover.

The Stonex S900A includes an E-Bubble tilt sensor that can be used to measure even difficult points with a tilt of the survey pole of up to 30°.

The S900A is optionally equipped with IMU technology. The crucial thing about the IMU technology is that it enables an angle of inclination of up to 60 ° on the measuring rod! Thanks to the IMU technology, the GNSS receiver is also insensitive to electromagnetic interference, such as can occur in the vicinity of power lines or transformer stations.
