ABSTRACT:
The invention provides a fast earth recovery procedure for an earth-pointing satellite, being compatible with known ARM and ESR safeguard modes, and including two successive phases shown in the flow chart of FIG. 2. The procedure may be entered at an intermediate step if the attitude deviation is sufficiently small. The invention is applicable to satellites with momentum bias attitude control or zero momentum attitude control.
