Advanced Space Antenna for GPS
We propose to develop a space based radiation hardened GPS transmit antenna capable of forming spot beams to enhance the GPS signal on the ground by greater than 5 dB. It is expected that our transverse compound hybrid antenna will provide as much as 30 dB gain over a hemispherical antenna allowing enhanced signals over specific areas as large as 500 km. A tradeoff between spot size and signal gain will be possible to overcome local jamming and spoofing environments. This antenna and control electronics will be hardened to survive in the natural space environment as well as the nuclear weapon environment described in the solicitation.
