Fleet management software from Geotab uses small devices in vehicles to track location data like position, speed and time. This data is sent via GPRS to Geotab's server farm for analysis. The software allows users to view vehicles in real-time or historically, send messages to vehicles, plan routes, and monitor engine health for predictive maintenance. Geotab's accurate tracking capabilities make it suitable for managing fleets and being used as expert evidence in legal cases.
