Research on Key Algorithms BDS/SINS Integration

This dissertation works on the pre-theoretical research and technical exploration with BDS/SINS integrated navigation system,which based on the pseudo-range and pseudo-range rate.Loose integration,tight integration and ultra-tight integration are discussed in this dissertation.And it established a pseudo-range and pseudo-range rate measurement for the concept of BDS/SINS combination system's state equation and measurement equation of Kalman filter parameters.The preparation of a combination simulation based on the pseudo-range and pseudo-range rate proved the fact that integrated navigation system can effectively suppress strap down inertial navigation system position and velocity errors of the divergence.This dissertation achieved good results:the misalignment is less than 0.03°and the error of east and north position and velocity are less than 10mand 1m/s respectively.
