Gmouse

Module-integrated RTK Antenna

Gmouse-M2 series consist of Gmouse-M20, Gmouse-M21 and Gmouse-M22 which are designed as an enhanced unit for agriculture, industrial machinery, automotive positioning, etc. It can be used to boost average accuracy of the original equipments to centimeter level. With the M2 series module built inside, Gmouse is capable of providing continuous, real-time and credible high-precision position and attitudes in harsh environments where satellite signals are interfered or blocked.
