Patent ID: 8768242

Claim:
A communications system comprising: a satellite hub, a remote satellite terminal, and a satellite configured to provide communications therebetween; said satellite configured to transmit to said remote satellite terminal an acquisition signal at a first satellite polarization angle, and a jamming signal at a second satellite polarization angle different from the first satellite polarization angle; said remote satellite terminal comprising an antenna defining first and second remote terminal polarization angles being adjustable to obtain polarization alignment with the respective first and second satellite polarization angles, a receive gain pattern being relatively wide about the first remote terminal polarization angle, and having a narrow width null at the second remote terminal polarization angle, and a transmit gain pattern having a narrow width peak at the second remote terminal polarization angle; said remote terminal further comprising a remote terminal controller configured to inhibit transmission without polarization alignment as determined based upon receiving the acquisition signal while filtering the jamming signal with the narrow width null of the receive gain pattern.
