Claim:
1. A computer-implemented method performed by a computer system of a satellite communications system, the method comprising: obtaining a beam plan that defines beams generated by a satellite that satisfy a set of communication service requirements; obtaining fade condition information that indicates amounts of fade at corresponding particular geographic areas covered by a beam; obtaining a fade mitigation plan that includes, for each of the particular geographic areas covered by the beam, a corresponding maximum amount of fade to mitigate for each particular geographic area, wherein the maximum amount of fade to mitigate for each particular geographic area covered by the beam differ between the particular geographic areas; determining whether the amount of fade at each particular geographic area indicated by the fade condition information exceeds the corresponding maximum amount of fade to mitigate that is included in the fade mitigation plan for each particular geographic area; determining, using a computer processor, a requested power for the amount of fade indicated by the fade condition information at each particular geographic area in which the amount of fade is determined not to exceed the maximum amount of fade to mitigate and a requested power for the maximum amount of fade included in the fade mitigation plan at each particular geographic area in which the amount of fade is determined to exceed the maximum amount of fade; selecting the greatest determined requested power for the amount of fade from among the multiple requested power for the amount of fade for the particular geographic areas covered by the beam as an amount of requested additional power for the beam; determining a modification to the beam plan based on the amount of requested additional power for the beam; and modifying the beam plan based on the determined modification.
