Product Introduction
DGS680 is a high-performance GNSS (Beidou+GPS+GLONASS) dual antenna positioning and orientation system launched by Wuxi Huilian Information Technology Co., Ltd. The system can achieve high-precision dual antenna orientation based on Beidou, GPS, and GLONASS. The two meter baseline orientation accuracy is less than 0.1 °, and there is no limit to the baseline length. The single point positioning accuracy can also reach 1.5 meters, and combined with the base station, high-precision RTK positioning can be achieved. This product integrates MEMS inertial sensors to complete integrated navigation and positioning orientation, overcoming the problems of short-term obstruction and signal loss in satellite navigation signals.
This system can be widely used in industries such as aerospace, mechanical control, system integration, exploration, precision agriculture, transportation, oceanography, ports, meteorology, national defense, research institutes, and colleges for high-precision differential positioning, orientation, navigation, ranging, deformation measurement, and timing.
