Abstract
Both Terrain Aided Inertial Navigation Systems (TAINS) and Gravity Aided INS (GAINS) are sorted out with Data-map Aided INS (DAINS). The reliability of DAINS relies on the characteristic of the reference map. The relationship has been dealt with among the sensors´ sampling cycle, the sensors´ precision, the data-map precision and its statistical characteristics. In this way, the related parameters are decided. Through simulation, different vehicle velocities along the same track in a defined region make for different precisions. Some perfect results are obtained.
