| 摘要 |
The invention includes a method of calculating corrections to a navigation solution based on accurate data, comprising:
receiving GNSS ephemeris, clock models and other navigation information from at least three GNSS satellites;
performing pseudo-ranging to the GNSS satellites;
resolving a PVT solution from the GNSS ephemeris, clock models and other navigation information and the pseudo range measurements the PVT solution including a statistical measure;
receiving differential GNSS data for calculating the corrections to the PVT solution calculating a corrected PVT solution based upon the differential GNSS data;
comparing the corrected PVT solution to an region defined by the statistical measure; and
rejecting the corrected PVT solution where the corrected PVT solution is not within the region. |
