以靶场交会测量中常用的 L公式为基础, 结合误差传递定律, 得出目标空间位置的测量误差公式。然后, 设置 4个不同测站, 以一条理想航迹为测量对象, 分别得到不同测站两两交会测量结果的误差曲线。对不同位置的双站交会结果以及它们之间的对比等 5种基本情况进行了详尽的对比分析, 得到了不同布站位置对双站交会测量结果的影响, 研究结果对实际工程应用中的经纬仪布站有重要参考价值。

Based on formula L commonly used at intersection measurement in ranges and combined with the law of error transfer, measurement error formula of the position of a target is obtained. Then four different stations are set up with an ideal flight path as measuring. The error curves of measurement results with double intersection mode from different measurement stations can respectively obtained. Five basic statuses such as the intersection result of double stations at different positions, comparisons of them etc. are analyzed and compared in detail. The measurement result of double stations intersection is influenced by station distribution. It’s the important reference value to station distribution of theodolites in actual engineering application.
