Reginald Victor Jones (or R. V. Jones) was born one hundred years ago today, on September 29, 1911. Jones was a British physicist who pioneered scientific intelligence, the art of applying scientific analysis to military intelligence. Part Richard Feynman, part Sherlock Holmes, Jones’ job was to anticipate German technical advances […]

Remembering R. V. Jones, Electromagnetic Warfare Pioneer

Time for more wireless updates: Here’s a great article about the British precursor to LORAN: “GEE.” GEE was one of the first implementations of the “Time-Difference-of-Arrival (TDOA)” concept used in some modern RTLS implementations. A simple explanation of Ekahau RTLS: “The Perfect Pairing of RF and IR.” Whatever happened to […]

An RTLS, RFID, and Wireless Update

Alfred L. Loomis invented the Long-Range Navigation or "LORAN" system in 1942. Source: U.S. Patent 2,884,628.
The Second World War spurred further innovation in RF-based navigation. The first wide-scale deployment of an RF-based location system was the Long Range Navigation or “LORAN.” LORAN was an evolution from a shorter range British system called “GEE.” Like GEE, LORAN employed synchronized impulse signal transmissions from paired transmit towers.
