Abstract: A beam splitting hand off systems architecture and method for using the same are disclosed. In one embodiment, the method comprises: generating a first beam with a single electronically steered flat-panel antenna to track a first satellite; generating a second beam with the single electronically steered flat-panel antenna to track a second satellite simultaneously while generating the first beam to track the first satellite; and handing off traffic from the first satellite to the second satellite.

Abstract: A multi-constellation transceiver, a satellite terminal containing the same, and a method using the same are disclosed. In some embodiments, the satellite terminal includes an antenna, a common port coupled to the antenna, and a plurality of modems to be switched into and out of use in real-time, via software commands, to allow transitioning between networks via software commands, each of the modems associated with a different satellite constellation. The satellite terminal also includes a multi-constellation transceiver, communicably coupled to the antenna via the common port and to the plurality of modems, to route signals between the antenna and individual modems of the plurality of modems.

Abstract: A method and apparatus for uplink power control based on power spectral density are disclosed. In one embodiment, the method for use by a terminal in a satellite communication system, the terminal having an antenna, a modem and a controller, the method comprising: determining the scan and skew of the antenna; obtaining, using the controller, a value representing a maximum allowed Power Spectral Density (PSD) for the determined scan and skew; determining, using the controller, a maximum allowable modem power based on the value representing a maximum allowed PSD, where the maximum allowable modem power is that which ensures that transmissions from the terminal do not exceed the maximum allowed PSD if the maximum allowable modem output power is not exceeded by the modem; sending, using the controller, an indication of the allowable modem output power to the modem; and performing one or more transmissions from the terminal based on modem outputs in accordance with the maximum allowable modem output power.

Abstract: Techniques for motion mitigation for uplink power control are disclosed. In one embodiment, a method for use in a satellite communication system comprises: generating a power margin associated with motion of an antenna of a satellite terminal; and generating a first power limit representing a maximum transmit power for the antenna based, at least in part, on the power margin.
