If so, can you please recommend a manufacturer?
Several companies manufacture off-the-shelf active RFID tags that also have a GPS device in them. Savi Technology, for example, introduced such a tag in 2009 (see Hybrid Tag Includes Active RFID, GPS, Satellite and Sensors). Whether or not these would be considered economical depends on your definition of that term.
