  1. Congratulations to Håkan Lans! by vinsci · · Score: 1 · on New ATC System To Rely On AT&T Cell Towers

    The ADS-B system was invented by Håkan Lans. His business home page: GP&C Systems International AB.

  2. Not Invented Here Syndrome by odourpreventer · · Score: 2 · on Inside FAA's GPS-Based Air Traffic Control

    There's already a tested, approved and standardised system; follow links in this page for info.

    But the inventor has for a long time been harassed by various US instances, in order to facilitate US interests, and that's why you won't see it in the USA.

  3. The Swedish inventor.. by alfadir · · Score: 1 · on Guiding Air Traffic Sans Radar With GPS

    Read more about the history and articles about this at GP&C Systems International AB and here are some interesting facts about Mr Håkan Lans, the inventor. He also holds one of three patents for the computer mouse and has a patent for color monitors for computers. Read more here!

  5. Is this H�kan Lans' system? by Anonymous Coward · · Score: 3 · on Guiding Air Traffic Sans Radar With GPS
    The Swedish inventor Håkan Lans (famed for among other things some nifty colour graphics patents that Hitachi bought a while back and a claim of inventing the mouse in the late sixties) has designed, constructed and tried to market a similar system (GP&C)for years, but the US aerospace lobby has been actively hindering him because they wanted to sell more of their old radar-based ATC systems to countries like India.

    Lans' system had an accuracy in the decimeter range (tenth of a yard) BEFORE the US DOD stopped fuzzying the GPS signal. This was achieved by a STDMA datalink (Self organising Time Division Multiple Access) and adding a few (there are currently around 30 of them covering Sweden, a country roughly the size of California) land-based transponder stations to the satellite coverage. The system basically use the land-based stations to enhance the satellite data. It is mature, operational and is an ITU and IMO world standard for large ships.

    On the terrorist/security aspect, I'd just like to point out that all civilian and military aircraft are required to carry and operate radar transponders at all times while in 'civilian' airspace so this system doesn't change anything in that respect.

    In short - it's a great system and everyone should use it; but it's hardly news.

  6. ADS-B was developed by H�kan Lans (Sweden) by Anonymous Coward · · Score: 1 · on Guiding Air Traffic Sans Radar With GPS
    Håkan Lans (Sweden) invented the "self-organising time-division multiple-access (STDMA) datalink" which ADS-B is based on.

    Scandinavian flag-carrier SAS has made a little bit of history with the first flight of a certifiable automatic dependent surveillance - broadcast (ADS-B) display in a commercial airliner. The move is a significant step along the long road to free flight. ANI was on board the 14 December [1996] flight from Stockholm Arlanda as the Swedish CAA performed certification tests on what is now called the MMI5000 (as in "man machine interface).
