摘　　要：双反射镜式光电经纬仪由于采用了反射镜跟踪头，轴系误差对测角精度的影响不同于典型光电经纬仪。本文从建立经纬仪三维直角坐标系入手，建立了该类型经纬仪轴系误差引起测角误差的数学模型，为精度分析和误差修正提供了依据．The head of mirror track is used in doble mirror photoelectric theldolite.Thismodel theodolite differs from typical theo dolite in the effect of the error of axises on pre-cision of angulor measure. This paper first leads out the mathematic model of angularmeasuring error being caused by axis errors through establishing three dimensional coor-dinate of this model theodolite.The mathenmatic model has more application value in pre-cision analysis and error correction.
