GA370 GNSS Survey Antenna

GeoRTK Navigation Limited

GA370 receives GPS L1/L2, GLONASS L1/L2 and BDS B1/B2/B3 frequencies, which can be used in land survey, marine survey, channel survey, seismic monitoring, bridge survey, container operation, agriculture applications. It is especially designed for precision triple frequency positioning. Customers can use the same antenna for GPS only or dual or triple constellation applications.
 
It has high gain and wide beam width to ensure the signal receiving performance of satellite at low elevation angle. The phase center of this antenna remains constant as the azimuth and elevation angle of the satellites change. Signal reception is unaffected by the rotation of the antenna or satellite elevation, so placement and installation of the antenna can be completed with ease.
