Abstract:
A one-piece lightweight personal tracking tag, comprising:a main housing having a contoured surface; a processor housed within said main housing; flash memory connected to said processor and housed within said main housing; a global positioning satellite (GPS) receiver housed within said main housing to obtain geographic location information; a wireless modem housed within said main housing for two way communication with a wireless network to exchange data with a centralized data system connected to said wireless network, wherein the processor determines a geographic position of the tag to verify the tag location through collection of location data from both said geographic location information from said GPS receiver and a geolocation implemented through the wireless network, weighs the location data from each of these sources to determine a probability of actual location, and transmits said weighted determination of the location data, as well as original geographical positional information gathered by the tag, to said centralized data system using said wireless modem.
