摘　　要：单台全站仪测量系统的精度不能满足高精度的空间坐标测量的精度要求。采用电子经纬仪进行空间角度交会,测出点位的水平角和垂直角,就可算出其空间坐标,在几米、几十米范围内精度可高于50μm,远高于单台全站仪单独定位的精度。因此,电子经纬仪测角系统,在各种高精度的工业测量定位中具有广泛使用价值。This paper points out that single set total station instrument system cant be satisfied precision requirement of high accuracy spatial coordinate measurement. It theodolite points out that when using electronic theodolite carrying out spatial angle intersection, and observing horizontal and vertical angles, and then calculating their spatial coordinates, the precision of spatial points could be higher than 50μm, far higher than the positioning precision by using only a total station instrument, so electronic theodolite angle measuring system has abroad applicant value in all kinds of industrial oositioning surveys.
