High-gain multibeam GNSS antenna

A satellite receiver, comprising:

• a lens having a curved front surface;
• a plurality of feeds disposed behind the lens each having a respective phase center, wherein the plurality of feeds comprises three feeds configured to receive satellite signals from respective satellites via the lens;
• and
• a processor configured to perform a triangulation operation to determine a time and a location of the satellite receiver using the satellite signals received by the three feeds after compensating for the respective phase centers of the three feeds.

A multi-beam Global Navigation Satellite System (GNNS) antenna system, comprising:

• a two-dimensional arrangement of a plurality of lenses, including a first lens;
• a plurality of feed sets disposed under respective lenses of the plurality of lenses, including a first feed set disposed under the first lens, wherein the first feed set comprises three or more feeds configured to receive signals from three or more respective satellites simultaneously;
• and
• a processor coupled to the plurality of feed sets and configured to determine a time and a position of the multi-beam GNSS antenna system at least in part by processing the signals received by the three or more feeds,
• wherein processing the signals received by the three or more feeds comprises compensating for a difference in phase center associated with each of the three or more feeds and subsequently performing triangulation using the signals received by the three or more feeds.
