GA830 GNSS Antenna
-
The Trimble GA830 GNSS 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 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
Zephyr 3 Base
-
The Trimble Zephyr 3 Base is recommended for all base station applications. This antenna is also suitable as a fixed rover antenna for use in high multi-path environments such as a marine construction barge.
Key features of the Zephyr 3 Base:
- Optimized for GNSS base station applications
- Comprehensive GNSS support
- Robust low-elevation satellite tracking
- Large ground plane for best multipath rejection
- Sub-millimeter phase center repeatability
- Ideal for fixed reference stations and GNSS infrastructure networks
Zephyr 3 Rover
-
The Trimble Zephyr 3 Rover is a high-performance lightweight GNSS rover antenna optimized for precision RTK applications.
Key features of the Zephyr 3 Rover:
- Optimized for GNSS rover applications
- Comprehensive GNSS support, including GPS Modernized signals, GLONASS, and Galileo
- Robust low-elevation satellite tracking
- Minimized multipath
- Sub-millimeter phase center repeatability
Zephyr 3 Rugged
-
The Trimble Zephyr 3 Rugged Antenna is intended for installations subject to high shock and vibration on the job site. Ideal for drilling rigs, marine vessels, cranes and other vehicle applications, it offers precise positioning with sub-millimeter phase center accuracy. 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 Zephyr 3 Rugged:
- Optimized for GNSS rover applications
- Comprehensive GNSS support, including GPS Modernized signals, GLONASS, and Galileo
- Robust low-elevation satellite tracking
- Minimized multipath
- Sub-millimeter phase center repeatability
- Additional high rejection filtering 1614 – 1624 MHz to reduce interference from Iridium transmissions
