METHOD FOR THE GROUND-BASED MONITORING OF EWF-TYPE ANOMALIES IN A POSITIONING SATELLITE SIGNAL

摘要

The invention relates to a method for the ground-based monitoring of EWF-type anomalies in a positioning satellite signal. The inventive method is particularly suitable for use in making GPS and SBAS satellite positioning signals reliable. Said method consists in performing an instantaneous statistical analysis (for approximately 1mn) of the correlation peak of the satellite signal receiver and comparing same to a long-term statistical analysis (several hours) by choosing 5 points which are characteristic of the peak (prompt, +/- 0.044 et +/- 0.088). If the result of the comparison is greater than a determined threshold, the corresponding signals are rejected.
