摘要
研究了准惯性定向探测卫星GPS接收天线的安装角度问题.根据卫星任务需求分析其姿态需求,再由姿态需求对GPS接收天线的安装方式进行理论分析和仿真计算,通过GDOP值优选了安装角度方案.仿真结果表明,GPS接收天线的轴向在本体±_y轴即轨道面法向或负法向方向附近.
The GPS （Global Positioning System） receiving antenna installation angle on a quasi inertial orientation of the exploration-satellite is studied. Firstly, according to the mission require ments, the satellite attitude requirements are analyzed. Secondly, theoretical analysis and simulation were conducted according to the attitude requirements of posture on the installation of the GPS re ceiver antenna installation angle, preferably by the GDOP （Geometric Dilution of Precision） values. Finally, conclusion is drawn based on the simulation results that the GPS receiving antenna axial is near to the iy axis of body reference frame, i.e. the orbital plane normal or negative normal direction.
