叙述了双站相差定位方法，描述了在程差差分项中所存在的波长整周数或相差的跳变现象，分析了波长整周数差值的测量误差对相对测距定位精度的影响。初步的误差分析表明，基于相差测量的双站测距方法在提高测距定位精度方面具有很好的潜在能力，但如不能准确地求解波长整周数的差值，且只要存有较小的误差，则整个测距定位精度将会急速变劣。

The location method based on dual?station phase difference measuring is discussed.The jump phenomenon of phase difference or wavelength integer is described in differential term of path difference.The influence on wavelength integer measurement error on relative ranging location precision is analyzed.The elementary error analysis shows that the overall location precision will hastily go bad as long as there is a less error during solving wavelength integer,although the location method based on phase difference has good potential in enhancing ranging precision.
