High End GNSS Receiver MEMS Inertial Navigation System for Surveying and Mapping
Product Description
GI300C is a compact inertial navigation system with fiber optic gyroscope (FOG) and micro-electromechanical system (MEMS) accelerometers, which can use external GNSS accurate timing and positioning information for inertial/satellite integrated navigation. When the external GNSS information is invalid, the inertial navigation system has a high ability to maintain the accuracy of pure inertial navigation.
