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.
