Geodetic Antenna for Multipath Mitigation

The choke ring antenna design is proven around the world to be effective in reducing the strength of most multipath signals. The new TrimbleŽ GNSS Choke Ring antenna has taken the choke ring design to the next level, with updated the electronics, improved low noise amplification, and GNSS tracking.

Key features:

• Jet Propulsion Laboratory (JPL) Scientific Design
• Trimble exclusive Dorne & Margolin element
• Tracks all existing and planned constellations
• Extensive precision rotation-testing: ensures 2 mm or better phase-center eccentricity and < 1mm phase-center repeatability
