Description
Summary:碩士 === 國防大學理工學院 === 兵器系統工程碩士班 === 98 === This paper mainly aims to establish the GPS (Global Position System) antenna stabilization and tracking platform to ensure the receiver beam aligned with the target to achieve high accuracy automatic tracking. The research objects focus on the derivation of platform equations and dynamic analysis to build the stabilized platform control structure. The azimuth and elevation control signals sent to the motor are provided by GPS data from the tracing target. The position data are first converted to global orientation data by the coordinate transformation formulas, and then, the data is filtered by the Kalman filter theory to give target position estimation during the next time interval. The system can be used for mobile vehicle tracking to counteract the vehicle swing or course changes from vibration to achieve stable mobile communications.
