Remote satellite terminal with antenna polarization alignment enforcement and associated methods

A method for operating a communications system comprising a satellite hub, a remote satellite terminal, and a satellite configured to provide communications therebetween, with the remote satellite terminal comprising an antenna and a remote terminal controller, with the antenna including a receive gain pattern being relatively wide about a first remote terminal polarization angle, and having a narrow width null at a second remote terminal polarization angle, and a transmit gain pattern having a narrow width peak at the second remote terminal polarization angle, the method comprising:

• operating the satellite to transmit to the 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;
• operating the remote terminal controller 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;
• and
• adjusting the first and second remote terminal polarization angles of the antenna on the remote satellite terminal to obtain polarization alignment with the respective first and second satellite polarization angles.
