ABSTRACT:
A tracking system includes a global positioning system (GPS) module and a modem for mobile communications both attached to a pet (or other trackee), and a virtual fence (which includes a base station sending a signal to a certain range and a receiver attached to the pet (or other trackee) and receiving the signal sent by a base station when the receiver is within the range of the base station). A portable virtual fence system includes a signal-sending base station, and a signal-receiver worn by a to-be-fenced pet or other trackee. Advantageously, the base station is portable. The size of the virtual fence can be expanded to fit any shaped geometry using signal repeater or transceiver devices. In addition, more than one pet can be tracked using a single virtual fence and base station. Upon confirmation that a trackee has breached the fence and should be tracked, a service center can provide location information of the trackee as well directions to the trackee by voice or transmission of mapping and other imaging displays to the responsible party seeking to locate the trackee. Power management is enhanced by either turning off the power to the tracking devices (e.g., GPS or GSM or other device) after a report, or by dynamically varying the time reports are made without deactivating the tracking devices.
