Abstract
The present invention concerns a method of optimization of processing of signals from satellite positioning systems in the case where at least two satellite systems cohabit and are utilized to obtain the position of a receiver.One of the systems is given preference on the basis of a criterion of performance and the satellites of the other systems are eliminated that are situated at an azimuth/elevation angle difference less than a threshold relative to the satellites of the preferred system.
