GNSS测量精度的全站仪验证方法研究OA

The total station-based accuracy verification method for GNSS measurement results is confronted with problems such as the lack of systematic theoretical support,non-unified evaluation criteria and confused indicators.To solve these problems,a new verification method is proposed based on the law of error propagation.This method deduces the mean square error by using the true errors in the ob-servation data,and clarifies the specific requirements for the relative accuracy of side length and angle measurement accuracy to meet the relevant specifications accordingly.The results show that this method not only provides a scientific calculation model for verifying the ac-curacy of GNSS measurement results with a total station in theory,but also has strong practical feasibility.It is applicable to the accuracy verification of GNSS control network results of different grades,and helps to improve the accuracy and comprehensiveness of the accuracy verification for GNSS measurement results.
