High-Performance, Rugged INS

The Geo-iNAV® is a high-performance, rugged GPS-aided inertial navigation system. The Geo-iNAV tightly couples an RTK-enabled dual-frequency GPS sensor with a wide range of IMU’s including fiber-optic gyro and ring- laser gyro IMU’s for the highest levels of accuracy. The Geo-iNAV provides on-board data recording and hosting of user applications via the SDK. Geo-iNAV is designed to meet a wide range of Air, Land and Sea requirements.
