Abstract
An asset location system includes a pager, a control processor, a GPS receiver and a cell phone. During normal operation, the equipment on board the tracked asset is in a low power or sleep mode. Upon receiving a location quaere from a call center, a signal or control processor is powered up. If location information is to be obtained from a particular asset, a GPS receiver obtains latitude and longitude information. This latitude and longitude information is put in a transmittable form by a modem. A cellular telephone module then transmits this information to a remote monitoring or response center. If desired, data reporting on asset condition may also be sent the remote monitoring or response center along with the location information.
