    • A combined earth/star system (1) for tri-axial determination of the position of satellites in space, comprising separate apertures with various directions of observation and joint image detectors (4) for the earth and star sensor. A joint optical system (2) for observing the earth and the stars and a deflector mirror (3) for deflecting laterally incident earth light onto the optical system can also be provided. A focal plane sensor with an array of image detectors (4) is located on one focal plane, whereby the integration time can be controlled. An evaluation unit determines the orbit and position of the spacecraft from the position and movement of the stars and the edge of the earth in the focal plane.

    • A celestial navigation system includes an optical device (2) for receiving light from a celestial object (5), a spectrometer for measuring a spectrum of the light in sufficient detail to identify absorption and/or emission features, and a processor (8) for processing the spectrum to match the spectrum, or a processed version thereof, against a set of reference spectra information in a database (10), a means for measuring the pointing direction of the optical device (12) and a clock (9). The matching may be on a maximum likelihood basis. The system is thus able, on identification of a single star, and, using commonly available navigational almanacs, to calculate a geographical position. The invention therefore allows celestial navigation to take place even when only one celestial object (that is also within the database) is visible, although improved accuracy may be obtained with multiple observations. Advantageously, the database includes stars of the K and/or M type, that have more characteristic spectral content.
    • 天体导航系统包括用于接收来自天体物体(5)的光的光学装置(2),用于足够详细地测量光的光谱以识别吸收和/或发射特征的光谱仪 (10)中的一组参考光谱信息来处理光谱以匹配光谱或其处理后的版本的装置,用于测量光学装置(12)的指向方向的装置, 和一个时钟(9)。 匹配可以基于最大可能性。 因此该系统能够识别单个恒星,并且使用通常可用的导航年历来计算地理位置。 因此,即使在只有一个天体(也在数据库内)可见的情况下,本发明允许进行天体导航,尽管通过多次观测可以获得改进的精确度。 有利的是,数据库包括K和/或M类型的恒星,其具有更多的特征光谱内容。

    • It is disclosed a method and system of passive detection of flying objects, whether moving or stationary, located in airspace or outer space even under severe adverse vision conditions. The method and system detect wide spectrum radiations coming from already predefined cells of celestial sphere and process all the information for a future decision. The method and system detect the presence of one or more flying objects, whether moving or stationary, in airspace or outer space due to the variations of the spectral characteristics which are generated when flying objects eclipse the cells during their passage by the line of sight between the sensor system and the correspondent celestial cell. The method comprises a physical and mathematical filtration which makes detection possible in adverse conditions of created vision, which are generally caused by interposition of absorbent, diffuse or radiant means. The method and system process the information and define position, height, speed, acceleration, path and flight attitude of the flying object in three dimensions.
