Abstract:
1. A satellite positioning receiver comprising: at least one receive channel, each receive channel configured to perform a combined processing of a first S carrier and code phase discriminators, the discriminators being common to both correlation circuits and configured to supply, from signals output from the integrators of the two correlation circuits, a complex local carrier generator for each carrier correlation path, each local carrier generator being driven by a carrier local phase signal output from at least one carrier numerically controlled oscillator NCOp controlled by a central carrier velocity signal, a local code generator configured to generate local codes for each code correlation path, each code generator configured to be driven by a local code phase signal output from at least one code numerically controlled oscillator NCOc controlled by the subcarrier velocity (or code velocity) signal, the local codes supplied by each code generator being offset by a positive differential delay correction +Δτ
