Orbcomm uses low-earth orbit and satellites to provide tracking, monitoring, and messaging capabilities to and from anywhere in the world. Similar to two-way paging or e-mail, the system is capable of sending and receiving two-way alphanumeric packages of data. The system is designed for such applications as tracking and monitoring vehicles, truck, trailer and cargo locations; tracking operating conditions of vehicles and trailers, including temperature alarms, open doors and full/empty conditions; and tracking, monitoring and reporting engine diagnostics.
