The TP26-U adopts GNSS/INS integrated navigation technology to overcome signal loss issues and enhance positioning continuity in complex environments such as buildings, tunnels, and viaducts. Supporting GPS, GLONASS, Galileo, BDS, SBAS, and QZSS (L1+L5), it integrates a high-performance six-axis MEMS sensor with a 3-axis gyroscope and accelerometer for precise motion tracking. With fine temperature compensation and factory calibration, the TP26-U ensures high accuracy, stability, and reliable performance across all applications.
