Actsoft makes the Comet line of software for a variety of different GPS needs. Comet Tracker uses GPS to track worker locations, record hours, store task info, and send out jobs, while Comet Mobile Worker expands the functionality of Tracker for even more uses. They also have a version of Comet Tracker for vehicles, allowing business to monitor their fleet of trucks. It monitors oil pressure, engine temperature, battery level and more, and can shut down the engine or notify the driver and dispatcher if a fault occurs. If it notices a low battery level while the engine is off, it will also shut down all electrical systems to save battery life. They should have some cool demos to show us at WES.
