AT600 Choke Ring Antenna
Other
Overview
The AT600 can track all existing and planned satellite constellations, which include GPS, GLONASS, BeiDou, BeiDou Global, Galileo, IRNSS, QZSS, SBAS and L-Band. Equipped with an IP67 rating, the AT600 is built to endure challenging environmental conditions, ensuring water and dust resistance. The AT600's sub-millimeter-level phase center error enhances measurement accuracy and stability, making it a reliable tool for land surveying, precision agriculture, deformation monitoring, CORS, etc.
