Overview

The Hemisphere GNSS A25 is an advanced land and marine antenna that is designed to include milometer accuracy and is drop-proof up to two meters. The Hemisphere GNSS A25 comprises of an aluminum base with an ASA plastic cap that has been pretreated to withstand the tough marine climate, which includes repelling salt, fog, and water spray. This modernized antenna can be used in all kinds of environments, including challenging locations, such as being near tall buildings or thick vegetation. This antenna can even prove its effectiveness at low land and marine levels, since this model has a higher multipath modification, a stable phase center, and strong SNRs.

Hemisphere GNSS A25 is compatible with current and future GNSS signals, including GPS, GLONASS, BeiDou, and Galileo. This antenna can be used for multiple applications, which include various surveys, single-frequency RTK positioning and navigation, precise guidance, and machine control.
