Trimble GNSS-Ti v2 Choke Ring Antenna

The Trimble GNSS-Ti v2 Choke Ring Antenna is a geodetic-grade GNSS antenna engineered for the most demanding reference station, monitoring, and scientific applications. Combining the JPL-designed 1/4 wave choke ring ground plane with proven Trimble antenna element technology, the GNSS-Ti v2 delivers exceptional multipath mitigation, low-elevation tracking, and long-term phase center stability.

Built to conform to strict geodetic standards of consistency and performance, the GNSS-Ti v2 achieves 2 mm or better phase-center accuracy and <1 mm phase-center repeatability, ensuring reliable, repeatable measurements across large GNSS networks. With comprehensive support for all current and proposed GNSS constellations—including GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS, SBAS, OmniSTAR®, and Trimble RTX™—it provides infrastructure-grade performance for permanent installations. Advanced second-generation filtering and a high-performance LNA further protect against nearband interference, while the fully sealed housing ensures dependable long-term deployment.
