Brief description of the mitigation of the multipath phenomenon of a satellite positioning receiver

摘要

The present invention relates to a first aspect of a process for the attenuation of the multipath phenomenon in a satellite positioning receiver, in which it is filtered, the disturbances affecting a pseudo - distance to a satellite, measured by the receiver by smoothing the pseudo - distance by the doppler measurements deduced from measurements of carrier phase of a signal emitted by the satellite, characterized in that the smoothing of the pseudo - distance is implemented with the aid of a smoothing filter not - stationary so as to control the transient discharge of a disturbance. The present invention also extends to a satellite positioning receiver comprising means for implementing the method according to the first aspect of the invention.
