GPS vehicle tracking
Vehicle or fleet positioning acquisition after a predefined distance and/or period of time, for example after reaching predefined geo-referenced points, when specific circumstances are verified or further to a request by the trackside system. Thanks to SIRFSTAR satellite prediction technology, all systems proposed by ISM are able to identify any type of vehicle within 3-metre precision, and can recapture a signal after a lack of coverage within 100 milliseconds at most.
