Overview

The Stonex S990A GNSS receiver has 800 channels and tracks all the present constellations and satellite signals (GPS, GLONASS, BeiDou, Galileo, QZSS & IRNSS). All GNSS signals are included at no additional cost.

The S990A features a new IMU system which allows tilted measurement (TILT) up to 60° for quick initialization, fast surveying and precise accuracy.

The S990A GNSS receiver is equipped with a number connectivity options: Bluetooth, Wi-Fi, UHF radio and 4G modem. The powerful internal battery has a working life of up to 10 hours and can be recharged via a type-c connector.

The color touch display and the WebUI are an easy and fast way to have the complete control of the receiver.

Thanks to aRTK function and Atlas correction service, Stonex S990A is also able to work in particularly difficult areas. Atlas delivers world-wide centimeter-level correction data through L-band communication satellites.

1PPS can be applied to scenarios that require precise synchronization time to ensure that multiple facilities work together or that use the same parameters for system integration based on precise time.
