POWER MANAGEMENT SCHEME FOR PROTECTING COMPONENTS MOUNTED ON SPACECRAFT

摘要

PROBLEM TO BE SOLVED: To provide a power management scheme for addressing problems of conventional power management schemes which can only limit the instantaneous maximum power and are not useable in a beam forming environment.

SOLUTION: A system for protecting a power unit 118 on a spacecraft 106 includes a ground station 108. The ground station 108 includes a power unit loading estimation and monitoring module 130 for estimating a power loading level on the power unit 118 of the spacecraft 106. The ground station 108 also includes a power regulator 128 to regulate the power of a signal for transmission from the ground station 108 to the spacecraft 106 to prevent overloading the power unit 118 of the spacecraft 106. The power of the signal for transmission to the spacecraft 106 is regulated based at least in part on an estimated power loading level on the power unit 118 of the spacecraft 106.
