Marine Receivers and Sensors
Marine construction presents its own unique challenges and requirements. No matter how complex your project, Trimble has marine construction hardware, software and positioning sensors to help you meet and exceed them.

Trimble offers several models of GPS and GNSS antennas to suit your specific application, signal tracking and budget requirements.

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 optimised for tracking low elevation satellites and delivering improved signal to noise ratios. With a ruggedised 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:

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:

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:

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.
