摘　　要：运用双频伪码/载波相位组合方式求解整周模糊度的方法实现星间链路中的载波相位测距。在双频伪码/载波相位组合原理的基础上,对不同组合方式下的测量误差进行分析,并研究了增大载波频率时的载波相位测距手段。仿真结果表明,算法能得到较准确的整周模糊度值和精度较高的测距值,实现了载波相位高精度测距。This paper realizes the carrier phase ranging in inter-satellite links with the method of dual-frequency pseudo-random code/carrier phase combination which is to solve the integer ambiguity. On the basis of dual-frequency pseudo-random code/carrier phase combination theory,the paper analyzes the measurement errors of different combinations,and studies the carrier phase ranging methods with the carrier frequency increasing. The result of simulation proves that the algorithm can get a more accurate value of integer ambiguity and a higher accuracy value of ranging,and it realizes the high precise measurement with carrier phase.
