Trimble® GA810 GNSS Antennas

Redesigned to support centimetre-level marine applications, the rugged Trimble GA810 GNSS antenna is a 100% humidity-proof thread mount antenna that is the ideal choice for any application in harsh environments. The optimal choice for dynamic applications requiring positioning and heading, the Trimble GA810 GNSS rover antenna is robust and delivers high performance. This low-multipath GPS antenna also prevents unwanted signal interference.



An ideal solution for critical applications where you need position and heading, the GA810 GNSS antenna can be used in the most rugged of environments thanks to the use of weather-resistant materials. It was specifically designed for land, marine or other vehicle applications that have an inbuilt magnetic mounting system.

Designed to offer full support for both present and near-future GNSS signals, the Trimble GA810 GNSS antenna offers outstanding GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS, OmniSTAR, Trimble RTX and SBAS and is the ideal choice when using the OmniSTAR G2 service.

Following a redesign, the Trimble GA810 GNSS antenna is designed to support high precision marine applications. It is equipped with a 100% humidity-proof enclosure and threaded mounting to protect from harsh environments commonly seen in marine applications.

One notable feature is the GA810’s resistance to multipaths. Caused by signals being reflected by different surfaces, the Trimble GA810 GNSS antenna resists unwanted signal interference or multipaths which can result in inaccurate measurements. The unit’s multiple constellation support expands the number of satellites available for positioning, especially in obstructed environments.
