Makarand writes "The Washington Post has an article about a vehicle tracking system built by a start-up 10-20.com. The system uses low orbit satellites for exchanging location information making it available anywhere in the US. The tracking device, the size of a paperback, can be installed in any vehicle and powered by a battery. A small antenna installed on top sends signals to satellites marking its position on a web-based map. The equipment costs around $1000 and monthly fees range from $20 to $65. The service plan will determine how often your position will be updated by the system. The tracking system FAQ on the company website is pretty detailed."
