Abstract
A method for detecting anomalies on satellite navigation signals consists in extracting the code error values delivered at the output of the N code discriminators, and comparing the extracted code error values with a same first threshold value corresponding to an acceptable maximum code error value and assigning a confidence index to each navigation signal received on each reception channel i, the confidence index depending on the result of the comparison carried out on the code error values.
