GA810 GNSS Rover Antenna

GA810 GNSS Rover Antenna

The GA810 GNSS rover antenna from Trimble is ideal for dynamic applications where positioning and heading are required. It is a robust, high performance and low-multipath GPS antenna which prevents unwanted signal interference.



The GA810 GNSS rover antenna is a good solution for critical applicatiomns where position and heading are required. Use of weather-resident materials allows operations in the most rugged environments. This antenna is specifically designed for land or vehicles applications with inbuilt magnetic mounting system.

The GA810 GNSS rover antenna has support for both present and future GNSS signals. It offers excellent GPS, GLONASS and OmniSTAR (L-Band) signal reception which makes it ideal for use with the OmniSTAR G2 service.

Signals being reflected from different surfaces causes the formation of multipaths. The GA810 GNSS rover antenna resists multipath or unwanted signal interference that can result in inaccurate measurements. Multiple constellation support increases the number of satellites available for positioning, particularly in obstructed environments.


  • Optimized for dynamic applications that require both position and heading
  • Recommended for best OmniSTAR reception
  • Comprehensive GNSS support, including GPS Modernized signals, GLONASS, Galileo and BeiDou
  • Robust low-elevation satellite tracking
