SA85 GNSS Survey Antenna

SA85 is a compact GNSS geodetic antenna, perfect as a rover antenna, but with adequate performance for CORS installation and monitoring applications. 

The SA85 has good phase center stability, effectively improves measurement accuracy and provides excellent positioning solutions. It is compatible with all GNSS geodetic receivers on the market and can be used for all static and kinematic measurement applications. The ability to receive low-elevation signals with high gain enables it to provide accurate and reliable position even under difficult conditions.
