Abstract: A method for determining an indicator of an amount of noise comprised within a received signal within a satellite communication network or a GNSS involves extracting a received modulating signal from the received signal. An estimate of the transmission delay is determined based on the in-phase component of the modulating signal. A prompt replica of the modulating signal is generated using the estimate of the transmission delay. A prompt quadrature correlation of the quadrature component of the received modulating signal and of the quadrature component of the prompt replica is determined, and the indicator of the amount of noise comprised within the received signal is determined based on the prompt quadrature correlation.
