Abstract
A system for augmenting the availability and performance of a satellite geolocation system uses a behavior model of at least one of the satellites of the satellite geolocation system. The behavior model includes parameters with which to augment the nominal operating range of the geolocation system. The behavior model also includes an indicator of the deviation between the behavior model and the real behavior of the at least one satellite, to enable a receiver to continue to use at least one satellite to determine the position of the receiver using the behavior model outside the nominal operating range of the satellite geolocation system. The parameters of the behavior model include at least a model of distortion of code chips transmitted by the at least one satellite to the receiver, or a model of distortion of the phase of the signal transmitted by the at least one satellite to the receiver.
