Abstract
Systems that enable observing celestial bodies during daylight or in under cloudy conditions.
Claims12
An optical system for determining navigational information, the system comprising:
- at least one satellite in Earth orbit;
- said at least one satellite providing at least one optical signal;
- a module, said module comprising an optical imager and a focal plane array detector;
- said focal plane array detector having sensitivity to said at least one optical signal;
- said optical imager configured to image a portion of the sky onto said focal plane array detector;
- and
- a computing component configured to receive the image from the focal plane array detector and to produce navigational information therefrom.

An optical system for determining navigational information, the system comprising:
- a spectral filter component configured to limit light to within a predetermined range of a spectrum;
- the predetermined range selected such that a signal is enhanced with respect to a background;
- a focal plane array, having sensitivity in the predetermined range;
- an optical subsystem optically configured to image a portion of the sky onto the focal plane array;
- and
- a computing component configured to receive the image from the focal plane array and to produce navigational information therefrom.
