#CMT# #/CMT# The method involves generating locally successive pseudo-random codes by a digital generator (23) that generates modified codes. The successive modified codes are shifted temporally with duration on each path. The signal in a base band is multiplied by modified pseudo-random codes, and the resultant signals are integrated on a preset period of time. Results of integration are interlaced temporally, and the generated signal is correlated by two sub-carriers for providing siding signal that is integrated on a preset period of time. #CMT# : #/CMT# An independent claim is also included for a receiver for receiving a radio electric navigation signal. #CMT#USE : #/CMT# Method for receiving a modulated composite radio electric navigation signal emitted by a satellite of a navigation system for permitting autonomous determination of position e.g. identification of a satellite, temporal reference, ionospheric correction, almanac or ephemeris of a reception device. #CMT#ADVANTAGE : #/CMT# The method receives radio navigation signal that is less consuming in calculator and energetic resources. The method ensures demodulation of signal which consumes less energy, and is rapid, while limiting the number of integration necessary to the demodulation of the signal. The method receives the signal which permits acquisition and monitoring of the signal. The method receives the signal with reliable sub-carrier, and is adapted to receive signal transmitted by global positioning system such as GALILEO system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a digital module of a receiver. 2 : Radiofrequency module 4 : Digital module 7 : Speed increaser 21, 22 : Module blocks 23 : Digital generator. |
