Thanks to the use of secured cloud software to compute positions, any GPS chipset can have its life extended 10-fold without expensive increases in battery capacity, enabling cost-effective monitoring of assets once deemed too expensive to track. With GPS now in use in most management centres, implementation is easy and inexpensive.
The Syntony SubWave GPS Coverage Extension allows for the monitoring of assets in real-time even in tunnels which are usually out of reach of GPS signals using existing telecommunication infrastructure to boost signals.
The system, which combines GPS with PTC solutions, was first used on the Stockholm metro in Sweden, and enables operators to position their teams and trains inside tunnels, either in a defined zone or at specific points. Zone-based positioning is intended to optimise rescue action in the event of emergencies. Continuous location tracking, which enables tracking of down to 2m of error, is designed for improvements to management on high-traffic lines.
