Abstract
A satellite navigation signal receiver connected to a legacy satellite navigation system receives a plurality of satellite signals. The receiver selects a subset of the plurality of signals and uses all available data from all of the signals to correct any errors in the subset of signals or otherwise increase the precision of the subset of signals. Alternatively, the receiver uses all of the available data in the plurality of signals to simulate idealized satellite signals that the legacy satellite navigation system uses to derive a location.
