System and method for geo-locating a receiver with reduced power consumption

A method for determining a position estimate for a remote asset comprising:

• collecting GPS signal information from multiple space vehicles at the remote asset, the GPS signal information being transmitted from each of the multiple space vehicles at a known signal frequency;
• extracting a set of signal delays for each of the multiple space vehicles;
• transmitting the set of signal delays and identification information for each of the multiple space vehicles to a ground station;
• processing the set of signal delays for each of the multiple space vehicles;
• retrieving information from a navigation database;
• and
• computing a position estimate for the remote asset using the set of signal delays, the information from the navigation database, and an estimated time of data collection at the remote asset.
