| Abstract: | The principle of the decorrelated pseudo range approach is presented. A weighted mean tracking error estimator is designed to estimate the GPS receiver code loop tracking error. Compared with the results from the uncorrected pseudo range measurements, the decorrelated pseudo range approach can reduce the integration system navigation errors, and improve the system navigation accuracy. |
