GPS全球卫星导航系统现代化工作,为多频姿态测量接收机的研制提供了基础条件。针对低轨卫星、导弹、飞机和舰艇等平台对姿态测量的使用需求,给出了由天线单元、测量单元和姿态解算单元构成的多频姿态测量接收机总体方案。研究了基于GPS多频组合噪声残差法实时探测与修复周跳、基于几何约束的单历元模糊度解算等关键技术,并给出了详细的计算方程和流程。对GPS单频定姿接收机和多频定姿接收机进行静态试验,证明后者在测姿精度和解算成功率方面都优于前者。

GPS modernization provides a foundation for developing multi-frequency a ttitude determination receiver.To satisfy the attitude determination requiremen ts of platforms such as low orbit satellites,missiles,aircrafts and naval vess els,a general design scheme for multi-frequency attitude determination receive r is given,which is composed of antenna unit,measurement unit and attitude comp utation unit.Then,some key technologies are investigated,including real-time cycle slip detection and correction based on GPS multi-frequency combination no i se residual,and the ambiguity resolution algorithm for single epoch using geome try restriction.The computation equations and flows are described in detail.Fi nally,a static test is carried out for the GPS-based single frequency receiver and multi-frequency receiver for attitude determination.The test results indic a te that,as for the attitude determination accuracy and computation success rati o,the multi-frequency receiver shows better performance than that of the singl e-frequency receiver.
