Product Information

Zephyr Geodetic Antenna

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, and Zephyr 2 Geodetic antennas offer full support for current and near-future GNSS signals in combination with the rugged durability of each antenna, means the investment in a Trimble Zephyr series antenna will last for many years.

Key Features

Comprehensive GNSS support, including:

  • GPS Modernization signals, GLONASS, BeiDou and Galileo
  • Robust low-elevation satellite tracking
  • Minimized multipath
  • Sub-millimeter phase center repeatability
  • Ideal for fixed reference stations and GNSS infrastructure networks
