摘要

14ABSTRACTMETHOD OF AND DEVICE FOR AUTHENTICATING A TRAJECTORY CALCULATED BASED ON RADIOLOCATION SIGNALSThe invention relates to a method of authenticating a displacement trajectory calculated from radiolocation signals received by a receiver embedded in a mobile unit. It comprises the following steps:a first step (100) of calculating a first profile of rotational movement of the mobile unit about a reference axis of the mobile unit based on data derived from the processing of the radiolocation signals;a second step (101) of calculating a second profile of rotational movement of the mobile unit about the same reference axis based on movement data derived from a measurement means independent of said radiolocation signals; anda third step (102) of comparing the first and the second rotational movement profiles of the mobile unit.The invention relates to applications for locating and calculating the trajectory of a mobile unit, notably satellite geolocation solutions.Figure 2
