Dynamic Virtual Boundary Methods and Systems

A system comprising:

• at least one physical computing device that
• accesses a positioning signal from which a geolocation accurate within a first margin of error is derivable for a real-time tracking device carried by a subject, the positioning signal generated by a satellite included within a satellite-based positioning system and received by the real-time tracking device;
• accesses a correction signal corresponding to the positioning signal generated by the satellite, the correction signal generated by a terrestrial positioning enhancement system and received by the real-time tracking device;
• accesses dynamic virtual boundary data that defines a user-specified geographic boundary configured to change in real time;
• continuously determines, based on the positioning signal and the correction signal, a refined geolocation of the real-time tracking device, the refined geolocation accurate within a second margin of error less than the first margin of error;
• continuously monitors, as the user-specified geographic boundary changes in real time, whether the refined geolocation of the real-time tracking device is within a predetermined distance of the user-specified geographic boundary;
• and
• provides, in response to a determination during the continuous monitoring that the refined geolocation is within the predetermined distance of the user-specified geographic boundary, an alert configured to assist in constraining the subject within an area defined by the user-specified geographic boundary.

A non-transitory computer-readable medium storing instructions that, when executed, direct at least one processor of a computing device to:

• access a positioning signal from which a geolocation accurate within a first margin of error is derivable for a real-time tracking device carried by a subject, the positioning signal generated by a satellite included within a satellite-based positioning system and received by the real-time tracking device;
• access a correction signal corresponding to the positioning signal generated by the satellite, the correction signal generated by a terrestrial positioning enhancement system and received by the real-time tracking device;
• access dynamic virtual boundary data that defines a user-specified geographic boundary configured to change in real time;
• continuously determine, based on the positioning signal and the correction signal, a refined geolocation of the real-time tracking device, the refined geolocation accurate within a second margin of error less than the first margin of error;
• continuously monitor, as the user-specified geographic boundary changes in real time, whether the refined geolocation of the real-time tracking device is within a predetermined distance of the user-specified geographic boundary;
• and
• provide, in response to a determination during the continuous monitoring that the refined geolocation is within the predetermined distance of the user-specified geographic boundary, an alert configured to assist in constraining the subject within an area defined by the user-specified geographic boundary.
