摘要
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 sta- tions are set up with an ideal flight path as measuring. The error curves of measurement results with double inter- section mode from different measurement stations can respectively obtained. Five basic statuses such as the inter- section result of double stations at different positions, comparisons of them etc. are analyzed and compared in de- tail. The measurement result of double stations intersection is influenced by station distribution. It＇ s the impor- tant reference value to station distribution of theodolites in actual engineering application.
