摘　　要：本文首先介绍了载波相位差分相对定位的原理;其次分析了整周模糊度解算方法并采用LAMBDA方法完成整周模糊解算;再次在相对定位解算过程中采取了共视卫星选择、备用基准卫星选择、周跳检测和修复、参数正确性验证等一系列改进措施;最后通过实例证明,采用的这些类措施是有效的,能够在静静、静动和动动条件下有效完成载波相位定位,并能够达到厘米级的高精度定位精度,提高了整周模糊解算的成功率。First, this paper introduces the theory of the carrier phase differential relative positioning; Second, the method of solving ambiguity is analyzed and the ambiguity is solved by the LAMBDA method; Third, A series of improving measures is used in the relative posi- tioning, such as, choosing common satellites, alternately main PRN, cycle slip detection and repair, accuracy of parameter validation, and so on; Finally, Through the data experiment, the results show that the measures are effective, can solve the relative positioning successful- ly and achieve the centimeter level positioning accuracy with a higher probability of success in static-static mode, static-dynamic mode, dynamic-dynamic mode.
