1. A single site beacon transceiver, comprising:

  • an omni-directional transceiver;

    a plurality of directional receiving antennas providing 360 degrees of coverage for receiving a signal; and

    a digital receiver for processing said signal, said digital receiver comprising a plurality of receiver channels and at least one processor, wherein the plurality of receivers are calibrated periodically and said processor estimates a coarse signal azimuth for said signal by calculating an amplitude monopulse ratio for said signal using two of the plurality of directional receiving antennas receiving the highest amplitude signal, and estimates a final signal azimuth for said signal using the estimated coarse signal azimuth and an interferometer baseline between said two of the plurality of directional receiving antennas.
