Abstract
A system for determining a locomotive within a railyard includes a base station, a base station receiver that receives location data pertaining to the base station location, a mobile receiver that receives location data pertaining to the location of locomotive, and a computer. The mobile receiver utilizes data from a group of satellites that are a subset of the satellite constellation used to obtain base station location data. The computer tracks base station location data and computes a position error for the base station. The computer applies the error to a locomotive estimated position resulting in an accurate locomotive location.
