GNSS Antennas for Heavy Highway and Marine Construction
To compliment the range of modular receivers for heavy highway and marine construction, Trimble offers five models of GPS and GNSS antennas to suit the customer's specific application and budget requirements.
Trimble Zephyr Series Antennas
The top of the range Trimble® Zephyr™ external GNSS antenna contains advanced technology for multipath reduction, outstanding low elevation satellite tracking, and sub-millimeter phase center stability. The Trimble Zephyr 2, Zephyr 2 Rugged, Zephyr 2 Geodetic antennas offer full support for current and near-future GNSS signals, including GPS L2C and L5, GLONASS, and Galileo. This technology future-proofing, in combination with the rugged durability of each antenna, means the investment in a Trimble Zephyr series antenna will last for many years.
Trimble GA Series Antennas
The Trimble GA series antennas (GA530 and GA810) offer reliable location GPS, GNSS or location RTK reception at an economical price point. The GA series are an excellent option for OmniSTAR signal reception and are recommended for applications with lower accuracy requirements than the Zephyr antennas.

Trimble Zephyr 2 Geodetic
The Trimble Zephyr 2 Geodetic 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.
With ability to track Modernized GPS signals, GLONASS, Galileo, OmniSTAR, and SBAS, the Zephyr 2 Geodetic is an excellent investment for the future.
Key features:
- Optimized for GNSS base station applications
- Comprehensive GNSS support, including GPS Modernization signals, GLONASS, and Galileo
- 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

Trimble Zephyr 2 and Zephyr 2 Rugged
The Trimble Zephyr 2 is a high-performance lightweight GNSS rover antenna optimized for precision RTK applications. The Zephyr 2 is also a good investment for the future, with ability to track Modernized GPS signals, GLONASS, Galileo, OmniSTAR, and SBAS.
The Trimble Zephyr 2 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.
The Zephyr 2 and Zephyr 2 Rugged can be used for OmniSTAR reception; however better OmniSTAR signal reception can be achieved using the Trimble GA810 antenna.
Key features of the Zephyr 2 and Zephyr 2 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

Zephyr 2 GNSS Antenna
Zephyr 2 RuggedTrimble GA530 GPS Antenna
The Trimble GA530 is an economical L1, L2, Beacon, OmniSTAR, and SBAS antenna for general Location GPS and Location RTK usage. It is also suitable for rover and moving base RTK applications, but with lower accuracy than the Zephyr 2 antenna.
The ability to track MSK Beacon signals makes it ideal for use in marine construction applications.
Key features:
- Economical GPS receiver for applications that require location accuracy
- Capable of using free differential corrections from MSK Beacons and SBAS

Trimble GA810 Antenna
The Trimble® GA810 Antenna is a general purpose GNSS rover antenna ideal for dynamic applications where position and heading are required.
The GA810 offers excellent OmniSTAR (L-Band), GPS and GLONASS signal reception, making it ideal for use with the OmniSTAR G2 service as well as GPS/GLONASS positioning and heading applications.
The GA810 is optimized for tracking low elevation satellites and delivering improved signal to noise ratios.
Key features:
- Optimized for dynamic applications that require both position and heading
- Recommended for best OmniSTAR reception
- Comprehensive GNSS support, including GPS Modernized signals, GLONASS, and Galileo
- Robust low-elevation satellite tracking
