stonex S900A

Powerful Precision with Atlas® Capability

Stonex S900A is equipped with an high performance GNSS board 394 channels and capable of supporting multiple satellite constellations: GPS, GLONASS, BEIDOU and GALILEO, including L-Band correction.

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 radiomodem with selectable frequencies, make S900A the perfect system for a GNSS Base + Rover.

Stonex S900A integrates E-Bubble sensor that allows the measurement of difficult points with the pole not levelled. It is possible to measure points with an inclination of the pole up to 30° even in harsh environments and in the presence of magnetic fields.

Thanks to measurement routine integrated into the field software, the management of tilt function is simple and intuitive.
