A tracking device installed on fleet trailers can integrate Global Positioning System (GPS) technology with the Internet to provide a secure cost-effective method for remote and accurate management of trailers. The self-powered unit has a rechargeable battery pack, a roof-mounted combination GPS and wireless antenna, and a roof-mounted solar panel. Vehicle location information is updated every two hours whether the trailer is stationary or in transit.
Cost: beginning at $800 per trailer (2000). Monthly service cost: $19 per subscriber with a 3-year contract (2000).
