Abstract: An apparatus, system, and method are disclosed for tracking the location of one or more target tracking apparatus with a master tracking apparatus. The master tracking apparatus communicates with the target tracking apparatus via radio frequency (RF) signals. The target tracking apparatus includes a tamper-resistant band and closure that are designed to resist unauthorized removal from the target subject and to alert the master operator of an attempted or completed unauthorized removal. The master tracking apparatus and the target tracking apparatus are each capable of initiating one or more alarm modes based on certain alarm events, such as activation of a distress alarm initiator by the target subject or activation of a check-in selector control by the master operator. Upon occurrence of an alarm event, the master and target tracking apparatus each communicates an alert signal to the other apparatus and each notifies the master operator or target subject of the occurrence of the alarm event.
