First claim
Opening claim text (preview).
What is claimed is: 1. A system for determining navigational information, the system comprising: at least one optical reference satellite, said at least one optical reference satellite providing at least one optical signal; said at least one optical reference satellite comprising at least one of optical reflectors or optical emitters; and a module, said module comprising an optical imager and a focal plane array detector; said module receiving said at least one optical signal. 2. The system of claim 1 wherein said at least one optical reference satellite comprises at least one optical emitter. 3. The system of claim 2 wherein said at least one optical reference satellite comprises a narrowband optical emitter. 4. The system of claim 1 wherein said at least one optical reference satellite comprises at least one optical reflector. 5. The system of claim 1 wherein said at least one optical reference satellite comprises a reflecting sphere. 6. The system of claim 1 wherein said module further comprises a timing circuit. 7. The system of claim 1 wherein said module further comprises an optical emitter. 8. The system of claim 1 wherein said module further comprises a narrowband filter. 9. The system of claim 1 further comprises a computing component receiving data from the focal plane array detector and outputting navigational information.
