Three dimensional electronic location

[Viewed 825 times]

A new method and apparatus enables the accurate and precise location of one to many RF emitters (e.g., cellphones, Ultrawideband, Bluetooth, WiFi and RFID devices) in near real-time, in three-dimensional (3D) space. The technology includes physically arranging four synchronized RF receivers at the four vertices of a virtual tetrahedron, which enables relative times of arrival calculated by the processor to precisely locate one-to-many RF emitters within that space. Existing 2D radiolocation methods utilizing one or more traditional methods of received signal strength (RSS), relative carrier phase (RCP), and relative-time-of arrival (RTOA) techniques resulting in accuracy and precision problems. These mistakes are eliminated with the new 3D method and apparatus.rnrnThe new method and apparatus combination is completely immune to all indirect RF reflections (“multipath”), false signals that would otherwise create location calculation errors. Location errors are thereby eliminated by simply ignoring all received signals that appear later in time than the last of the first four signals to arrive at the four synchronized receivers.
The technology is protected by four issued Unites States patents including 14 independent and 68 total method and apparatus claims. The technology is useful in transportation including automotive, aerospace, navigation, GPS as well as telecommunications applications such as emergencylocation in three dimensions as well as marketing applications especially in multistory applications. White paper on website more fully describes technology.


Financial information

Prima is open to a sale or license including the Prima website and the demonstration software. The invention has not been previously sold or licensed. It is believed that many telecommunications and navigation (land/sea/air) applications exist and that many companies are investigating this technology.
