Powerful Performance with Atlas®

Stonex S900A GNSS Receiver

The Stonex S900A is equipped with a high performance, 800 channel GNSS board capable of supporting multiple satellite constellations including GPS, GLONASS, BEIDOU, GALILEO, QZSS and IRNSS, and L-Band correction.

A fast internet connection is guaranteed through the 4G GSM modem for receiving correction data and managing maps in the background. In the extraordinarily compact structure there is the integrated UHF radio, Bluetooth and Wi-Fi modules which ensure a reliable data flow to the controller, making the S900A the perfect system for a GNSS + Rover Base.

The Stonex S900A integrates the E-Bubble sensor, allowing for the measurement of difficult points where the pole is 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.

The S900A can also be equipped with the optional IMU technology for measuring points up to 60° inclination.

Electronic Bubble with Optional IMU

With the E-bubble, which is immune to magnetic fields, measurements can be taken up to an inclination of 30° and measurements are automatically made when the pole is vertical. An optional IMU module is available which allows for measurements to be taken up to 60°.

Hemisphere GNSS Board with 800 Channels

The Stonex S900A incorporates the Hemisphere board P40 which has 800 channels and supports GPS, GLONASS, BEIDOU, GALILEO, QZSS, IRNSS and L-Band correction. The internal antenna combines the GNSS, Bluetooth and Wi-Fi modules to optimise space.

Atlas® and aRTK

The S900A comes with aRTK which provides precise positions up to 20 minutes after the receiver loses the land based RTK correction source. In conjunction with Atlas® correction (which is a subscription service) it is possible to acquire measurements down to 8cm accuracy. 

2 rechargeable and replaceable intelligent batteries

The S900A comes with two, 7.2V – 3.400mAh intelligent lithium batteries. These batteries have charge indicator LED’s on them and are easily removed and recharged. It is possible to hot swap the batteries.
