This study evaluated two satellite concepts (Halo - a satellite orbiting the L sub 2 point, and Hummingbird - a satellite hovering near L sub 2 for a lunar libration point L sub 2 satellite to be used as a tracking and communications link with the far side of the moon. Study areas included flight dynamics, communications, attitude control, propulsion, and system integration. On the basis of these studies, both the concepts were proved feasible. However, the Halo was shown to be the better concept. The Halo concept should be investigated in more detail, and technology studies in the areas of multiple feed antennas and specific attitude control techniques should be initiated. (Author)
