Navigation system using celestial radio emissions

A celestial navigational system comprising:

• a clock providing a current time;
• an antenna system providing a radio areal image of the sky within a range from 29 MHz to 30 GHz at a terrestrial location, the radio areal image linked to the current time;
• a template areal image of expected celestial radio emissions within the range from at least one celestial object referenced to a terrestrial longitude and latitude and a reference time;
• and
• an electronic computer matching the radio areal image to the template areal image to determine a longitude and latitude of the terrestrial location based on a positional offset between the template areal image and the radio areal image and a time offset between the current time and the reference time;
• wherein the antenna system includes an array of spatially separated antennas providing signals to circuitry generating the radio areal image from the signals by interferometry;
• and
• wherein the array of spatially separated antennas are a two-dimensional array of antennas separated along two perpendicular axes.
