Method and apparatus for distribution of satellite navigation data
First Claim
1. A method of distributing satellite navigation data, comprising:
- processing satellite signals at each of a plurality of reference stations to receive a respective plurality of satellite navigation data streams, wherein each of the satellite navigation data streams comprise a plurality of subframes carrying different portions of ephemeris data, and another plurality of subframes carrying different portions of an almanac;
forming packets in response to said plurality of satellite navigation data streams to generate a plurality of packetized satellite navigation data streams, wherein each one of the plurality of subframes carrying different portions of ephemeris data, and each one of the plurality of subframes carrying different portions of the almanac from one of the plurality of satellite navigation streams are placed in different packets;
sending each of said plurality of packetized satellite navigation data streams to a processing system;
removing, at said processing system, duplicate packets within said plurality of packetized satellite navigation data streams to generate a combined packet stream; and
sending said combined packet stream into a communication network.

Abstract
A method and apparatus for distributing satellite navigation data is described. In one example, satellite signals are processed at each of a plurality of reference stations to receive a respective plurality of satellite navigation data streams. Packets are formed in response to said plurality of satellite navigation data streams to generate a plurality of packetized satellite navigation data streams. The packetized satellite navigation data streams are sent to a processing system. The processing system removes duplicate packets within said plurality of packetized satellite navigation data streams to generate a combined packet stream. The combined packet stream is then sent into a communication network.
