Low-cost, Drift-free DGPS Locomotive Navigation System. High Speed Rail IDEA Program;Final rept. Nov 99-Feb 01

摘要

This project developed a high-speed rail train navigation system to accurately determine train location, including on which of two or more parallel tracks a locomotive is located. The system includes a three-receiver, three-antenna GPS heading reference system and parallel-track resolution software. The system also includes a heading rate sensor and a Doppler radar system to determine position, velocity, and heading when GPS satellite coverage is interrupted. Tasks in this concept exploration project included the developed and evaluation of the system software, including a parallel track resolution algorithm. Field tests with the GPS attitude system mounted on the test locomotive were conducted on BNSF.
