Abstract
A system, methods, and apparatus for dual antenna transfer switching are disclosed. In an example embodiment, a dual antenna system includes antennas, antenna control units, a transfer switch, and a modem. For example, the transfer switch may transfer a connection between antennas based on changing satellite visibility, upon entering a preprogrammed blockage zone or an unexpected loss of satellite visibility. The transfer switch may receive GPS data from an external GPS unit and/or the antenna control units and buffer the GPS data to a modem. The transfer switch may provide a modem receive-lock signal to retarget a line of sight. The transfer switch may transfer the connection between the antennas based on satellite visibility including signal reception quality and/or a modem receive-lock status. The transfer switch may, based on a difference in antenna uplink transmission power, attenuate a higher power antenna to be balanced with a lower power antenna.
