Abstract
An independently integrated navigation system (SINS) is discussed using the distance-transfer-unit (DTU) to assist the strapdown inertial navigation system (SINS/DTU). Taking the velocity differences between SINS and DTU as the observed values, a closed Kalman filter is adopted to estimate and correct the errors. The simulation results indicate that the SINS/DTU can effectively improve on the following navigation parameters: velocity, latitude and longitude, yawing and attitude angle, position of track-reckoning etc.
