초록

A method and an apparatus for controlling the attitude and momentum of a spacecraft while deploying an appendage from the spacecraft. The method comprises the steps of predicting an environmental torque the spacecraft will be subjected to during deployment of the appendage, computing a magnitude and a direction of momentum to add to the spacecraft to at least partially oppose the predicted environmental torque, and storing the computed magnitude and direction of momentum in at least one of the momentum wheels before deploying the appendage.

청구항

What is claimed is: 1. A method of controlling an attitude of a spacecraft while deploying an appendage from the spacecraft, the spacecraft having substantially variable mass properties from the appendage deployment, and having a plurality of momentum wheels and a plurality of solar wings, comprising the steps of: predicting an environmental torque the spacecraft will be subjected to during deployment of the appendage; computing a magnitude and a direction of momentum to add to the spacecraft to at least partially oppose the predicted environmental tor...
