Abstract: A tracking system including a transceiver, an attachment system for connecting the transceiver to a wearer, a microprocessor periodically connected in wireless communication with the transceiver, and a database operationally connected to the microprocessor. The transceiver is operationally coupled to a GPS satellite system and generates sets of datapoint pairs, with each respective datapoint pair including a geographic location value and time value corresponding to when the geographic location value was measured. The transceiver from time to time communicates a set of datapoint pairs to the microprocessor for storage in the database, and the attachment system generates an alert signal if disengaged from the wearer.
