Abstract
A spacecraft configuration including a service module which carries optical stabilizing equipment for stabilizing the spacecraft relative to two inertially fixed targets together with solar arrays rigidly attached thereto so as to extend in the orbital plane and never obstruct the field of view of the optical stabilization equipment. The payload module is attached to one face of the service module by means of rotary interface structure to be able to continuously point to the earth.
Claims2
A spacecraft configuration comprising a service module, said service module having first sensor means arranged to point to a first inertially fixed target and second sensor means arranged to point to a second inertially fixed target, said first and second sensor means providing 3-axes attitude control information for stabilization of the spacecraft;
- solar arrays rigidly attached to the service module such that when they are deployed in orbital configuration, they leave the field of view of said first and second sensor means unobstructed;
- rotary interface means having first attachment means on one face for attachment to a first face of the service module and having second attachment means on its opposite face;
- and a payload module attached to said second attachment means on the rotary interface means;
- said rotary interface means being arranged to permit said payload module to continuously point to the earth.
