US Patent 9591441 Long-life asset tracking

A method and system for long-life asset tracking is disclosed. One example utilizes an activation module to provide an activation signal to at least a portion of the long-life asset tracker. A position determiner receives the activation signal and determines a location of the long-life asset tracker with a first level of accuracy or a second level of accuracy, wherein the second level of accuracy is more accurate than the first level of accuracy and wherein a default mode of operation is to utilize a radio locator for position determination instead of a navigation satellite system module to extend the life of a power source of the long-life asset tracker. An information provider module to broadcast the location of the long-life asset tracker is also disclosed.
