Abstract: A satellite positioning receiver is disclosed having at least one receive channel. Each receive channel is intended to perform a combined processing of a first S1 and a second S2 radiofrequency signals separated in frequency. The signals are received by analogue paths of the receive channel then digitized to be processed in digital receive paths. Each receive channel has a first (160) and a second (162) correlation circuits, respectively receiving the first and the second received digitized signals. Carrier and code phase discriminators are common to both correlation circuits. A local code generator is provided for each code correlation path. The local codes are offset by a positive differential delay correction +Δτcal for one of the correlation circuits and a negative differential delay correction −Δτcal for the other. These corrections tend to compensate for the relative delay difference between the two signals in the analogue paths of the receive channel. A phase differential correction device Δφcal tends to compensate for the phase differential deviation between the two signals occurring in the analogue paths of the receive channel.

Abstract: The invention relates to methods of processing signals subjected to interference. It consists, when this signal is formed of a first wideband channel and of a second narrowband channel modulating one and the same carrier in which these signals are cut off for the duration of the interference, in using a single phase loop and a single code loop to process these two channels simultaneously. It makes it easier to process signals in satellite based navigation systems of the GPS type when they are scrambled by the DME-type distance measuring system signals, as well as more generally making it possible to increase the robustness of the processing by joint processing of the bands broadcast to the users.
