High accuracy RTK DR Dead-Reckoning GNSS mouse for GIS, USB GNSS RTK receiver for drone mapping/precision farming/autonomous driving
RTK GNSS Mouse RTK28A High Precision USB GPS Receiver for Surveying, UAV, and GIS
Compact RTK GNSS mouse with centimeter-level accuracy. Ideal for surveying, UAV mapping, precision agriculture, autonomous vehicles, and GIS data collection.
Overview
The RTK28A is a high-performance dual-frequency (L1+L5) multi-system + inertial navigation positioning terminal. It features a built-in high-precision RTK inertial navigation module and a dual-frequency GNSS high-precision antenna. It integrates RTK algorithms and, in conjunction with the high-precision positioning services of the national Beidou augmentation network, achieves centimeter-level positioning accuracy, making it the most cost-effective high-precision GNSS terminal.
The RTK28A supports the next-generation Beidou-3 signal system and all global civil navigation satellite systems (including BDS, GPS, Galileo, QZSS, and SBAS).
