Train signal and communication system
SGA has developed a number of ASICs for use in an automatic train protection (ATP) system. The components are used to monitor the signal lamps in the signal towers and to communicate wayside information to the on-board computer in passing trains. Information like the state of the signals further up the track, or speed restrictions, is transferred via an RF transmission link as the train travels over a balise that is situated between the rails.
These products are developed for Bombardier.
The SGA parts are used in a harsh environment in a system where there are high demands on system reliability. Our customer needs parts with a long term supply since this is an application with a very long life time. The programmability built into the ASICs makes them very flexible and wireless field programmable.
