T20 Palm GNSS Receiver
GNSS Receivers
Overview
Small enough to fit in a pocket, T20 is only 48mm thick with the battery and weighs 0.67kg. With SinoGNSS K8 platform and 3rd generation IMU, T20 can adapt to various complex environments and collect accurate data. Powered by a 10,000mA lithium battery, it can stand up for 12 hours. Lighter, Thinner, and Stronger - T20 is specifically designed for land survey, agriculture, machine control, and GIS.
