Product Detail

Stonex S5II / S990A GNSS RTK Receiver Cheap GPS Survey Instrument
Stonex S990A is a 800 Channels GNSS receiver characterized by a new feature that enhance the performances of field surveys.
The new IMU System allows tilted measurement (TILT) up to 60°: quick initialization, fast and precise survey.
S990A Receiver is equipped with all important connectivity capabilities: Bluetooth, Wi-Fi, UHF radio and 4G modem. The internal battery of 10.200mAh allows to work for 9 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.
