Abstract
A system and method for an extensible tracking system. A set of autonomous tags detect their location such as via GPS and broadcast their location to other nearby tags. Using separate communication technology, each tag can also communicate with an associated user device such as a smart phone. The user device(s) provide a user interface for queries into the system. The broadcasts among all tracking devices insures no reliance on a single tracking device, and associating tags with a respective set of user devices eliminates reliance on a central system for tracking to locations of all tags.
