To get high-precision attitude of missile in “SINS/CNS” integrated guidance system, which has significant affected the attitude control system and accuracy of error separation, for example, the gyro drift, we built “SINS/CNS” measurement amendment program of missile boost phase for remote-range ballistic missile. Extended Kalman filter is applied to determine real-time, high-precision missile attitude...
For GPS positioning, it is normally required that there be at least four GPS satellites in view. However, due to the frequent blockage of signals in an urban environment, it is difficult to meet that requirement; therefore, the operation of the GPS receiver may be interrupted. How to deal with this problem so that the service can be continuous is the main theme of this paper. The pseudorange predictor...
This paper describes a method for fusing an inertial position measurement from an Ultra-Short Baseline (USBL) sonar with a water-relative velocity measurement (from DVL, ACM, or other device) to improve knowledge of an underwater vehicle's inertial position. The goal is accuracy sufficient to enable closed-loop position control in the midwater. In this paper we describe the implementation of a kinematic...
