Ultra-Small Fiber Optic Integrated Navigation System
Product introduction
The ER-FINS-50 is a high-performance, ultra-compact GNSS +fiber-optic gyroscope integrated navigation system. The ER-FINS-50 integrated navigation system has a built-in high-performance GNSS board with Feiner latitude and longitude, supports BDS, GPS, GLONASS three-system RTK high-precision positioning, adopts independent intellectual property rights of fast carrier phase ambiguity solution technology and multipath suppression algorithm, can quickly and accurately solve centimeter-level position information, can receive RTCM data from multiple ground reference stations at the same time, and supports short, medium and long baseline RTK solution.
The ER-FINS-50 integrated navigation system adopts the smallest optical fiber IMU device in China, which can adapt to a variety of use environments; The use of high-reliability closed-loop fiber optic gyroscopes and accelerometers can ensure the measurement accuracy through a number of compensation techniques.
The integrated navigation system has a built-in multi-language Web GUI, which can realize hands-on configuration, graphical data display and remote upgrade;The integrated navigation system also features convenient and easy-to-use web configuration interface, which greatly reduces the threshold of use, and has a rich interface to adapt to various application scenarios.
It can be widely used in high-precision surveying and mapping, mechanical control, displacement and deformation monitoring, precision agriculture, exploration, transportation, etc.
