<p>Navigation information for a first navigation system (110) is computed based on interference signals (120) and satellite signals. The first navigation system (110) comprises means for receiving N satellite signals capable of being processed and at least M interference signals (120), 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 (110). Based the at least M interference signals (120) and the N satellite signals received and capable of being processed, the navigation system (110) computes navigation information for the first navigation system (110).</p> |
