For the highest multi-path rejection requirement with millimeter accuracy, we offer an L1/L2 Choke Ring Antennas. All antennas are configured for marine or ground survey. They utilize light or very light assembly. A special radome is UV protected.
Choke Ring, White
The AT2775-382 is a high performance multi-frequency, multi-constellation L-Band and GPS antenna. It is NGS calibrated and can be used for RTK networks, scientific, and machine control applications.
It’s ruggedized all weather housing protects it from the elements under the most extreme conditions. It has exceptional capability to pick up satellites low on the horizon which is beneficial in rough sea conditions. This antenna is used for the harshest environments like marine/offshore positioning or survey.
Typical applications include:
Geodetic Antenna for Real-Time Kinematic (RTK) applications
Precision Rover Antenna for Land Survey applications
The AT2775-54 is a high performance GPS antenna. It’s ruggedized all weather housing protects it from the elements under the most extreme conditions. It has exceptional capability to pick up satellites low on the horizon which is beneficial in rough sea conditions.
