A spacecraft (20) traveling in a volume of space receiving radiation from a radiation source (38) and having a spacecraft body (22) having a first axis of symmetry, X, a second axis of symmetry, Y, and a third axis of symmetry, Z. The spacecraft body (22) rotates about a rotation axis, T, which defines a nonzero angle ( lambda ) of inclination relative to the Z axis. A radiation receiving element (28) is rotatably attached to the spacecraft body (22) along an axis, Y. A control system (44) is employed on the spacecraft (20) for rotating the spacecraft body (22) about the rotation axis T by an angular amount ( gamma ) and rotating the radiation receiving element (28) by an amount ( alpha , beta ) so that the radiation receiving element (28) is normal to the radiation source (38). <IMAGE> |
