A good investment for the future
Trimble offers several models of GPS and GNSS antennas to suit your specific application, signal tracking and budget requirements.
Trimble modular GNSS antennas represent a good investment for the future, with the ability to track modernized GPS signals, BeiDou, GLONASS, Galileo, MSS (CenterPoint RTX, OmniSTAR), QZSS and SBAS. The GA830 antenna also tracks the MSK Beacon signal.
GA830
The Trimble GA830 Antenna is a general-purpose GNSS antenna designed for the marine environment. It can be used for both position and heading applications and has excellent RTK and Mobile Satellite Services (MSS) performance.
The GA830 is optimized for tracking low elevation satellites and delivering an improved signal to noise ratios. With a ruggedized housing and reliable performance, the GA830 is intended for installation on construction barges, pile driving rigs, marine vessels, cranes and other dynamic marine platforms. High rejection RF filtering reduces the effects of Iridium transmissions, which can often be the cause of GNSS signal loss on marine construction vessels.
Key features:
- Economical GNSS antenna for precision RTK marine applications
- Ruggedized housing for marine conditions
- Additional high rejection filtering 1614 – 1624 MHz to reduce interference from Iridium transmissions
- Capable of using free differential corrections from MSK Beacons and SBAS
- Recommended for best MSS reception (includes Fugro Marinestar®, OmniSTAR and CenterPoint RTX)
- Comprehensive GNSS support
- Robust low-elevation satellite tracking
