Abstract
An asset locator device including (a) a wireless receiver capable of receiving an identifier signal transmitted from a short range wireless transmitter device; (b) a wireless transmitter capable of transmitting a message to a space based network; (c) a positioning system capable of determining the location of the locator device; (d) a vibration sensor; and (e) a controller. The controller instructs the asset locator to: (i) attempt to detect the identifier signal from the transmitter device if the vibration sensor senses vibration; and (ii) transmit a signal, including an asset location, to the space based network if: (1) the identifier signal is not detected; and (2) location fixes from the positioning system indicate a location change of the asset.
