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 Sand a second Sradiofrequency 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 () and a second () 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 +Δτfor one of the correlation circuits and a negative differential delay correction −Δτfor 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 Δφtends to compensate for the phase differential deviation between the two signals occurring in the analogue paths of the receive channel.
