Double Antenna GPS/SINS Integrated Navigation System

Modern navigation systems capable of real-time and accurate carrier motion information requirements. In the field of integrated navigation, satellite navigation, it is currently the most commonly used GPS) and strapdown inertial navigation (SINS) integrated navigation system can make up for the inadequacy of their individual navigation circumstance, and has the advantages of high precision, low cost, simple structure, is now by far the most popular research direction. GPS/SINS integrated navigation is general position and velocity as the measurement to revise inertial navigation system, with the gradual development of GPS orientation system, the attitude and position and speed of the same as the measurement of all combination method is becoming a hot research topic.In this paper, based on the mechanism of GPS/SINS integrated navigation system and characteristics on the navigation computer based on DSP + FPGA platform design for reliable information fusion technology, through the relevant experiment proved that this system has a good effect.
