A space-based server network architecture () which permits on demand transfer of mission and control data between client satellites () in an orbit about earth and an earth station () irrespective of the location of the client satellite () relative to the earth station (). The architecture includes a plurality of server satellites () located spaced apart in a earth orbit above the orbit of the client satellites (). The server satellites () provide substantially total world-wide communications coverage to and connectivity with designated and authorized earth stations () and the plurality of client satellites (). Each server satellite () includes: a communications downlink (a,b) for providing intercommunication with designated and authorized earth stations within its field of view; communications crosslinks (a,b) for providing intercommunications with other server satellites within its field of view; and communications links (a,b) for providing intercommunication with a client satellite within its field of view. Client satellite control data originating from an earth station is passed directly to an accessible server satellite, which then passes the control data either directly to the intended client satellite if within its communications field of view, or forwards the control data to a server satellite having direct communications access to the intended client satellite. Mission data from a client satellite can at any time be transmitted to a designated earth station, irrespective of its location on earth, by transmitting first to a server satellite within its communication field of view, where the mission data is then either downlinked directly to the designated earth station if within its communications field of view, or transmitting to a server satellite having communications downlink access to the designated earth station.

A seeker device, such as a seeker head, includes a housing for both a first optical assembly and a second optical assembly. In the preferred embodiment, the first optical assembly is an infrared telescope having a fixed, relatively narrow field of view for receiving incoming energy via a first path through an optical opening through the housing. The second optical assembly may be a pivotable mirror that is pivoted to provide a wide field of regard. The incoming energy that impinges the pivotable mirror enters through a second path through the optical opening. The energy from the pivotable mirror is redirected into the infrared telescope. In the preferred embodiment, the redirection is achieved by a dichroic mirror that has a high transmissivity with respect to long wave infrared energy and a high reflectivity with respect to mid wave infrared energy. In an exoatmospheric mode, the long wave infrared energy that passes through the dichroic mirror from the narrow field of view is utilized, while in an endoatmospheric mode mid wave infrared energy from the wide field of regard is utilized.
