The A25™ GNSS Antenna has been designed to support millimeter accuracy on land and marine applications. The A25 GNSS antenna offers support for present and future GNSS signals, including GPS, GLONASS, BeiDou, and Galileo.
A25 is a multi-GNSS precision antenna and is ideal for various applications including surveys, single-frequency RTK positioning and navigation, precise guidance, and machine control. Use the A25 antenna in challenging environments (such as near buildings and foliage) as it has superior multipath mitigation, stable phase center and strong SNR's, even at low elevations.
The rugged housing utilised by A25 is made of an aluminum base that has been pretreated for the marine environment and will withstand salt, fog, and spray. The antenna easily passes the two-meter pole drop test.
