SYSTEM, METHOD AND COMPUTER READABLE MEDIA FOR IDENTIFYING THE TRACK ASSIGNMENT OF A LOCOMOTIVE
First Claim
1. A system for identifying a track assignment of a locomotive traveling along a track, comprising:
- at least one onboard receiver on said locomotive for wirelessly communicating with a plurality of satellites to provide a respective initial location of at least one onboard antenna on said locomotive; and
at least one wayside receiver wirelessly coupled to said at least one onboard receiver;
said at least one wayside receiver positioned adjacent to said track for wirelessly communicating with said plurality of satellites to provide a respective corrected location of said respective initial location of said at least one onboard antenna to said at least one onboard receiver.

Abstract
A system is provided for identifying the track assignment of a locomotive traveling along a track. The system includes at least one onboard receiver on the locomotive for wirelessly communicating with a plurality of satellites to provide a respective initial location of at least one onboard antenna on the locomotive. Additionally, the system includes at least one wayside receiver wirelessly coupled to the at least one onboard receiver. The at least one wayside receiver is positioned adjacent to the track to wirelessly communicate with the plurality of satellites to provide a respective corrected location of the respective initial location of the at least one onboard antenna to the at least one onboard receiver. A method and computer readable media are also provided for identifying the track assignment of a locomotive traveling along a track.
