Zusammenfassung: | A multi-antenna device for rejection of multipaths in a satellite navigation system and an associated method. A method is provided for estimating the parameters of useful signal and multi-path signalsoriginating from a radiolocation signal emitted by a satellite, a location device comprising at least two sensors able to receive the signal. The method comprises the steps of: correlating the signalreceived by the sensors with a local code by means of correlators, constructing, for each sensor, a sampled intercorrelation function intercorrelating the signal received with the local code, determining a spatio-temporal intercorrelation function on the basis of the concatenation of the intercorrelation functions obtained in the previous step for each sensor, estimating parameters representativeof the useful signal and of the multi-path signals by applying a maximum likelihood algorithm, the representative parameters including at least one complex amplitude estimated independently for eachsensor.
