    Omega was shut down several years ago as GPS became fully operational. 

    Omega operated at a radio frequency of 10 kilohertz (yes, 10 KHz).   Since the optimal size of an antenna is inversely proportional to the frequency, Omega antennas were giants.   As a result, the tallest structures on two of the continents (Africa and either South America or Australia) were the Omega antennas operated by the US government.

    Subject: [NavList] OMEGA

    Has anyone on this list had experience using OMEGA? I know how it worked (centilanes, etc.) but I wonder how it worked in practice. Is this system in place or was it shut down? when?
