AI Technical Summary

Technical Problem

In existing technologies, the positioning results of GNSS satellite positioning systems are often affected by various factors, leading to inaccurate positioning. How to accurately evaluate the positioning quality of terminals to improve the accuracy of positioning results is an urgent problem to be solved.

Method used

By acquiring satellite observation data at the current epoch of the terminal, the first type of statistical parameters of the observation pseudorange residual and the second type of statistical parameters of the single-difference observation pseudorange residual are calculated, and the quality of the terminal positioning results is evaluated by combining these parameters.

Benefits of technology

It enables the accuracy assessment of terminal positioning results, thereby improving the accuracy of positioning results.
