An automatic celestial navigation system for navigating both night and day by observation of K-band or H-band infrared light from multiple stars. In a first set of preferred embodiments three relatively large aperture telescopes are rigidly mounted on a movable platform such as a ship or airplane with each telescope being directed at a substantially different portion of sky. Embodiments in this first set tend to be relatively large and heavy, such as about one cubic meter and about 60 pounds. In a second set of preferred embodiments one or more smaller aperture telescopes are pivotably mounted on a movable platform such as a ship, airplane or missile so that the telescope or telescopes can be pivoted to point toward specific regions of the sky. Embodiments of this second set are mechanically more complicated than those of the first set, but are much smaller and lighter and are especially useful for guidance of aircraft and missiles. Telescope optics focus (on to a pixel array of a sensor) H-band or K-band light from one or more stars in the field of view of each telescope. Each system also includes an inclinometer, an accurate timing device and a computer processor having access to catalogued infrared star charts. The processor for each system is programmed with special algorithms to use image data from the infrared sensors, inclination information from the inclinometer, time information from the timing device and the catalogued star charts information to determine positions of the platform. Direction information from two stars is needed for locating the platform with respect to the celestial sphere. The computer is also preferably programmed to use this celestial position information to calculate latitude and longitude which may be displayed on a display device such as a monitor or used by a guidance control system. These embodiments are jam proof and insensitive to radio frequency interference. These systems provide efficient alternatives to GPS when GPS is unavailable and can be used for periodic augmentation of inertial navigation systems.

A solid-state image sensor includes photoelectric converters positioned either in a complementary color filter array or in the Bayer color filter array. The solid-state image sensor either adds together electric charges obtained by 9 photoelectric converters that relate to one color in each portion of six rows and six columns of the photoelectric converters so as to output a resulting electric charge as one pixel, or outputs the electric charges obtained by 9 photoelectric converters that relate to one color as 9 pixels without added together. By adding together the electric charges, the resolution of an image becomes one ninth of the case where the electric charges are not added together, and the sensitivity becomes 9 times higher than the same. The control unit not shown in the drawing determines a time length for photoelectric conversion assuming that the electric charges are not added together. If the determined time length is longer than a predetermined threshold, the actual time length for photoelectric conversion is reduced to {fraction (1 / 9)} of the determined time length, and an image is generated based on the resulting electric charges that are outputted after the electric charges stored in the photoelectric converters are added together.
