The TAG88 is Toknav's fully automated GNSS-guided land leveling system, combining a GNSS antenna, control unit, and a 10.1-inch touchscreen display. It supports GPS, BDS, GALILEO, GLONASS and Beidou signals for roughly +/-2.5 cm accuracy, and can operate continuously without repositioning a base station within about a 30 km radius. It displays real-time cut/fill volumes and automatically adjusts blade position, working with scrapers, graders, ripper and paddy leveling blades, and tractor navigation setups for large-scale farmland and terrain leveling.
