ABSTRACT:
The method of the invention, which is applicable, in particular, to making positioning signals from GPS and SBAS satellites reliable, consists in performing an instantaneous statistical analysis (of around 1 mn duration) of the correlation peak from the satellite signal receiver and in comparing it to a long-term (several hours) statistical analysis by choosing 5 points which are characteristic of the peak (prompt, ±0.044 and ±0.088). If the result of the comparison exceeds a given threshold, the corresponding signals are rejected.
