Description

The GA830 is optimized for tracking low elevation satellites and delivering 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 of the GA830:

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
