Patent 7852262 was granted and assigned to Cybernet Systems Corporation on December, 2010 by the United States Patent and Trademark Office.
This invention is a wireless mobile indoor/outdoor tracking system. It is designed to track the absolute position of all nodes in a network indoors and outdoors. The system uses GPS positioning when a signal is available and RF ranging when it is unavailable. When indoors, a minimum of three network nodes must receive a GPS signal to determine absolute position. A mesh network is used to make the system mobile and to create an avenue for data to be transmitted to a remote base station.
