给出了基于载波相位平滑伪距技术的GPS/INS组合导航的公式并进行了误差分析.用算例对该算法进行验证,结果表明:如果GPS周跳较少或不发生周跳,基于载波相位平滑伪距技术的GPS/INS组合导航的精度较伪距紧组合导航有较大的提高;反之,精度提高不显著.
給齣瞭基于載波相位平滑偽距技術的GPS/INS組閤導航的公式併進行瞭誤差分析.用算例對該算法進行驗證,結果錶明:如果GPS週跳較少或不髮生週跳,基于載波相位平滑偽距技術的GPS/INS組閤導航的精度較偽距緊組閤導航有較大的提高;反之,精度提高不顯著.

The phase smoothing code method is introduced into the GPS/INS tight integration. It could improve the navigation accuracy without the reference station and the kinematic real-time ambiguity resolution. Through the calculation of a sample, it is shown when cycle slip occurs few times during a period, the method of phase smoothing code can improve the accuracy of GPS/INS integration greatly, but if cycle slip occurs many times then the accuracy of GPS/INS integration will be improved slightly.
