ABSTRACT:
A method and apparatus for determining the length of a train utilizing received signal such as a reference signal from a global positioning system or the like is disclosed. A first receiver receives a signal, such as a reference signal from a global positioning system or the like, from which a first position on a train may be determined. Similarly, a second receiver receives a signal from which a second position on the train may be determined. A processor, operatively coupled to the first and second receivers, determines the length of the train based on the first and second positions.
