摘　　要：在对野外测量作业成果质量检核时,经常使用全站仪测距与大地线长比较做检核,但发现在新疆地区检核时出现误差较大的现象,由此展开分析可知,主要是由于经度的变化影响反算的大地线长,在短距离时使用高斯平均引数公式反算大地线长与全站仪测距具有可比性,而使用全站仪测距检核空间坐标计算的距离更为可靠。When we inspect the quality of the field survey results,we often use the total station to compare the distance measurement with the length of the geodesic line.However,we find that there is a big error in the verification in Xinjiang.Therefore,the analysis is mainly due to the influence of the change of longitude on the length of the reverse geodetic line.In short distance,using Gauss mean argument formula to calculate the length of geodetic line is comparable with total station distance measurement,while using total station distance measurement to verify the space coordinate calculation is more reliable.
