1. A non-transitory computer readable medium storing a plurality of computer-executable instructions wherein said plurality of computer-executable instructions comprises:
- receiving each of a plurality of packetized-satellite-navigation-data streams from a plurality of reference stations;
removing duplicate satellite-navigation-data streams within said plurality of packetized satellite-navigation-data streams so as to generate a combined packet stream; and
sending said combined packet stream.

Abstract
A method and apparatus for distribution and delivery of global positioning system (GPS) satellite telemetry data using a communication link between a central site and a mobile GPS receiver. The central site is coupled to a network of reference satellite receivers that send telemetry data from all satellites to the central site. The mobile GPS receiver uses the delivered telemetry data to aid its acquisition of the GPS satellite signal. The availability of the satellite telemetry data enhances the mobile receiver'"'"'s signal reception sensitivity.
