1. A signal processing unit for determining a location of a vessel in motion, the signal processing unit including a processor configured to:
obtain position data of a non-geostationary satellite associated with arrival times when signals are received by the non-geostationary satellite from the vessel;
selecting a plurality of candidate locations to determine proximities to the location of the vessel based on the position data; and
processing the plurality of candidate locations to determine the location of the earth-based vehicle,
wherein the signal processing unit is located remote from the vessel.
