Abstract
Automatic gain control device for satellite positioning receivers characterized in that it comprises means for estimating the temporal occupancy rate of the pulses within the useful band, closed-loop control of the automatic gain control being applied in an optimal manner as a function of the said temporal occupancy rate, in such a manner as to reduce the influence of the pulsed interference within the band and out-of-band; notably, an AGC decision module returns a control signal for the attention of a non-linear function module applying a given weighting to the signals resulting from a comparison between the power or the amplitude of digitized input signals and a setpoint threshold value CAGC.
