Abstract
Under low speed and low dynamic,applying integrated GPS Navigation system and INS Navigation system to the carrier,the author research on the navigation algorithm and navigation performance when using low cost and low precision Inertial Measuring Units. In this paper,an algorithm that is suitable to low dynamic carrier is presented by researching in normal GPS/INS Navigation technology,especially kalman filtering. And it get verified through simulation. The results show that the navigation filtering method is adapted for low dynamic carrier.
