Analysis of RDSS Positioning Performance under Elevation Constraints

When using RDSS positioning under elevation constraints, traditional positioning accuracy estimation methods may not reflect the impact of satellite ranging error and elevation error on positioning performance accurately. In order to evaluate RDSS positioning performance more accurately, the RDSS positioning principle is presented, and the weighted position dilution of precision (WPDOP) is used to replace the traditional algorithm. The positioning error calculated by WPDOP is closer to actual results, indicating better prediction capability of positioning performance. Under different elevation error conditions, the position dilution of precision (PDOP) distribution of the service area indicates that the difference between the two precision factors is mainly affected by the elevation error and latitude, while the influence of longitude is small.
