Dual antenna GNSS / INS system NV-GI120 close combination

Dual antenna GNSS / INS system tightly integrated NV-GI120 Dual-Antenna GNSS / INS Tightly Integrated System NV-GI120 NV-GI120 dual antenna miniaturization of MEMS tightly integrated navigation system tightly coupled technology precision, low power, 16-channel, single-frequency dual-antenna GNSS receiver output of raw carrier phase and pseudo-range and MEMS inertial measurement unit closely, with small size, light weight, and high cost. NV-GI120 tightly integrated navigation system can provide the level of attitude, heading and other fixed posture information, longitude, latitude, altitude and other location information, as well as three-dimensional acceleration, angular velocity inertial measurement information; and by extending the height of the barometer odometer or other auxiliary sensor further improve system accuracy and applicability, it can be widely used without aircraft, vehicle navigation, aviation and platform stability control and other fields. Applications 1, 2 unmanned aircraft, aviation 3, stable platform 4, 5 long-distance transport, ship attitude, heading the dynamic measuring 6, 7 Mining and Auto-farming, trains and container tracking Features 1, GNSS / INS closely integrated; 2, low price, small size, light weight; 3, Rugged design to ensure that harsh environment can work; 4, anti-vibration shock and electromagnetic interference; 5, highly scalable barometer odometer or other sensors (optional).
