Abstract
Navigation information for a first navigation system is computed based on interference signals and satellite signals. The first navigation system comprises means for receiving N satellite signals capable of being processed and at least M interference signals, where M=K−N and K equals the minimum number of satellites required to be tracked for unambiguously determining navigation information for the first navigation system. Based on the at least M interference signals and the N satellite signals received and capable of being processed, the navigation system computes navigation information for the first navigation system.
