An integrated GPS/INS system provides more accurate estimates of position and attitude compared to individual systems. Availability of inertial sensors and GPS cores has opened up new opportunities for low cost INS/GPS systems which find wide spread application. Different integration techniques of GPS/INS integration have been implemented to obtain accurate position in navigation systems. A loosely...
In this paper, the navigation model combining GPS and INS is detailedly analyzed, whose extended Kalman filter (EKF) algorithm is given. The principle and mathematical model of multiple MVDR beamforming is given. On the basis of this, the anti-jamming model of navigation system based on GPS/INS and antenna array is proposed. The simulation results show that the position error of single beamforming...
GPS can provide both military and private users with accurate information about user position and velocity. However its data rate is low as well as 1~10Hz, and it will not provide a continuous and reliable information among mountains, dense forests and high building. Inertial Navigation System (INS) is an autonomous, all-weather navigation system that can provide continuous information of position,...
