Product Information

High Performance GNSS Support for Airborne Mapping and Surveying

The Trimble AV37 Aviation Antenna has been designed to support centimeter level accuracy for airborne applications and track SBAS signals all in one compact design. It is fully certified by the FAA for aircraft installations.

ROBUST, CERTIFIED GNSS AVIATION ANTENNA

Mapping and surveying from the air using GNSS requires survey grade antenna technology in a compact and reliable form factor. The Trimble AV37 GNSS Aviation antenna achieves this without compromising performance.
