Abstract
A system and method for preventing collisions between vehicles, such as railway vehicles, by exchanging data regarding track position of the vehicles. By use of an on-board track database (550), the system provides an indication of the distance between vehicles based not on line-of-sight but on track distance. Additionally, a system and method for accurately determining location of railway vehicles without the use of a network of trackside indicators. The disclosed system uses a gyro (530), tachometer (520), and a satellite position determination system (510), along with a track database (550), to maintain highly accurate estimates of measurement errors and track position.
