Satellite-Based Positioning System Reception Device Comprising a Function for Detecting False Lock-Ons

摘要

A satellite-based positioning system reception device comprises a function for detecting false lock-ons based on a linear combination of complex signals arising from correlation pathways between a signal received from a satellite and a prompt local code and a plurality of local codes shifted by determined delays with respect to the prompt local code. An advantage is that the function for detecting false lock-ons makes it possible to remedy the false lock-ons due to multi-path phenomena.
