摘要

Applying inertial navigation system (INS) to aid satellite navigation is considered as one of the best way to achieve high dynamic and weak signal environment. With the improvement of the GPS software receivers and the emergence of low-cost high-precision micro-electro-mechanical systems (MEMS) inertial measurement unit (IMU), IMU-aided GPS navigation system came into being. In this paper, the system framework design, accurate Doppler information assistance, multi-mode navigation data synchronization, integrated navigation filtering algorithm and other key technologies are reviewed and analyzed. Based on the summary of the existing technologies and research results, the future directions and challenges are prospected.
