Abstract
A method for calibrating a multichannel GNSS receiver which does not require the use of a specific signal generator and which may be implemented directly on the basis of simple measurements taken from a receiver in operation comprises determining a first, broadband equalization filter which may be positioned at the output of the RF reception channels and at the input of the correlators in order to correct the mismatch between the various RF reception channels. The invention also consists of determining a second, narrowband equalization filter in order to correct residual phase and gain errors.
