The invention relates to a method of optimizing the resources used in a satellite or aircraft telecommunications system (onboard segment). The method includes expressing the difference in consumption EdB between the consumption of onboard power and the consumption of onboard bandwidth as a function of a plurality of terms including a quality indicator, an informational term expressing onboard parameters and a corrective term. The quality indicator QaF′depends on the antenna system, onboard and on the ground, and on conditions of propagation and interference of the medium. The informational term ℑdB depends on modem parameters. The term K′ depends on onboard parameters such as the maximum incoming flux density and the bandwidth. A corrective term CdB characterizing the consumption of onboard power attributable to the upward noise which is amplified and transposed on board. At least one of the parameters QaF′, K′, ℑdB is modified in order to tend toward the cancellation of the absolute value of the term EdB. |
