Dual Receiver EGNOS+SDCM Positioning with C1C and C1W Pseudo-Range Measurements

The paper presents an approach to the simultaneous use of SDCM and EGNOS corrections for two GNSS receivers placed at a constant distance. were applied GPS code measurements on L1 frequency: C1C C1W. is based mainly constrained least squares adjustment, but horizontal vertical coordinates, Kalman Filter was in order reduce pseudo-range noises. It allows obtaining higher autonomous accuracy GPS/(SDCM+EGNOS) positioning than when using only GPS/EGNOS or GPS/SDCM system. final dual-redundant solution, which SBAS systems used (EGNOS+SDCM) pseudo-ranges (C1C+C1W) present, yielded RMS errors 0.11 m coordinates 0.25 coordinates. Moreover, analysis developed mathematical model determined 3D with proved be much more reliable single presented can not precise navigation, also some geoscience applications remote sensing where required.
