High performance MEMS positioning fixed position system POS1100 using high performance MEMS gyroscope and quartz acceleration meter, and professional GNSS board combination, GNSS / INS data fusion software processing can provide accurate location information (latitude, longitude, and altitude), attitude (pitch and roll, airlines to), and 3D acceleration and angular speed dynamic information. It is a high performance of its small size, light weight, integration of the MEMS positioning attitude system. Scalable multi-sensor (odometer, barometric height meter, etc.) in order to improve the accuracy and applicability of the system, which is widely used in mobile measurement of figure, the low altitude photogrammetry, special vehicle positioning and orientation, weapon system test and precision agriculture field.
