Hemisphere GNSS A52 Geodetic Antenna
The Hemisphere A52™ antenna is a multi-GNSS precision antenna and is ideal for various applications including geodetic surveys, RTK positioning and navigation, precise guidance and machine control. Designed for use in challenging environments, such as near buildings and foliage, because of its superior multipath mitigation, stable phase center and strong SNR’s even at low elevations.
