Abstract: INS/GNSS integrated system can provide accurate and reliable navigation information, but the complex dynamics and GNSS signal blockage all lead to the divergence of INS navigation solution caused by sensor errors. The paper mainly works on accuracy analysis and enhancement of low-cost MEMS INS/GNSS integration for land vehicle navigation, and focus on applying the dynamics constraints to aid INS and deducing the forward velocity based on the constraints. Field experiments show the improvement in navigation accuracy, especially in the complex dynamics environment.
