The Trimble Zephyr 2 GNSS antenna is a high-performance lightweight GNSS rover antenna optimized for precision RTK applications. The Zephyr 2 has the ability to 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 Rover and Zephyr 2 Rugged can be used for OmniSTAR reception; however better OmniSTAR signal reception can be achieved using the Trimble GA810 antenna.
