GA830 GNSS Antenna

Trimble GA830 GNSS Antenna

Manufacturer: | Category:

The Trimble GA830 antenna is a general purpose GNSS antenna designed for marine applications.



The Trimble GA830 can be used for both heading and position applications, and has excellent Mobile Satellite Services (MSS) and RTK performance. It is optimized for delivering improved signal to noise ratios and tracking low elevation satellites.

With a ruggedized housing and reliable performance, the GA830 has been designed to be installed on marine vessels, cranes, pile driving rigs, construction barges and other dynamic marine platforms.

The effects of Iridium transmissions are reduced through high rejection 1614 – 1624 MHz RF filtering. These transmissions often cause GNSS signal loss on marine construction vessels.

As the unit is capable of using free differential corrections from SBAS and MSK Beacons, it is recommended for best MSS reception, including Fugro Marinestar, OmniSTAR and CenterPoint RTX.


  • Ruggedized housing for marine conditions
  • Economical GNSS antenna for precision RTK marine applications
  • Robust low-elevation satellite tracking
  • Comprehensive GNSS support
