摘要： An automatic gain correction circuit for radiofrequency signals applies notably to the regulation of the amplification of signals for satellite radionavigation. The automatic gain correction circuit is able to receive an input radiofrequency signal and to deliver an output radiofrequency signal of which a mean amplitude is slaved to a setpoint. It comprises means for modifying the setpoint as a function of the mean amplitude of the input signal between a minimum setpoint value and a maximum setpoint value, the minimum setpoint value corresponding to a first mean amplitude of the input signal and the maximum setpoint value corresponding to a second mean amplitude of the input signal, the first mean amplitude being lower than the second mean amplitude.

摘要： The method of determination of the position of a mobile receiver using at least four satellites of which at least one first satellite transmits a first signal on one frequency, the broadcasting of the first signal being single-frequency, and of which at least one second satellite transmits second and third signals respectively on a first and a second frequency, the broadcasting of the signals being two-frequency, the receiver including means for reception of at least two frequencies, makes it possible to determine the position by a calculation of at least four pseudo-distances corresponding to the distances between each satellite and the receiver. The calculation of a pseudo-distance at the first frequency includes a step of estimation of the inter-frequency bias between the first and second frequencies.
