1. A 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 output power based on the value representing a maximum allowed PSD, the maximum allowable modem output power being 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 maximum allowable modem output power to the modem to control the modem to limit modem output power to no more than the maximum allowable modem output power to ensure that transmissions from the terminal do not exceed the maximum allowed PSD; and
performing one or more transmissions from the terminal based on the modem output power in accordance with the maximum allowable modem output power.
