An asset in a group is automatically tracked wherein each asset is tagged, and at least one transport means are associated with at least one Proximate GPS (PGPS) location devices each equipped with a sensor which is receptive to the presence of a known asset. The sensor is able to detect the type of tag(s) associated with assets and associated with the transport means. The transport means transporting a PGPS device during the course of it activities passes by, associates with and/or may relocate a known tagged asset, the PGPS automatically detects the asset tag and stores the first sensed GPS location, asset tag ID, first time in a newly created PGPS record. When the transport means moves away from the asset by greater than a proximate distance set for the PGPS device reader the asset tag no longer is detected and the PGPS device recognizing such creates then adds to an asset transaction history log the previously stored last reading GPS location associated with the asset and last time of reading with associated details. The next time the PGPS is in communication with the PGPS host system the PGPS transaction history log of one or more transactions is transmitted to the host system providing the most recent asset location, associated transaction details and optionally specific relocation location path history for each asset in the transaction history log. Optionally the current location of the transport means can be mapped on the PGPS device in real-time together with the start and end locations of the asset, movement path and other associated information stored in the PGPS data base accessible independent of the host system availability.
