SRmini RTK GNSS receiver

SRmini is a new intelligent IMU GNSS receiver launched by SunNav. It supports all satellites and 1520 channels, small and powerful, making a faster, more accurate and more stable user experience.




SRmini has 5 satellites signals 16-band service: Strong signal, more satellites, anti-blocking, instant measurement after power-on; Using a new combined antenna, GNSS, WiFi, Bluetooth are integrated into one, and the wireless signal is better.




IMU Tilt measurement

New tilt measurement algorithm for increased productivity. support 60 degree IMU Tilt surveying.




Small and powerful, work better

The volume is reduced by 40%, and the weight is reduced by 30%, making the field surveying work easier




Ionospheric suppression, cloud integration

With ionospheric suppression capability, significantly improving the fixation rate and accuracy under the influence of the ionosphere
