摘要

Process and device for the treatment of the output signals of an optical sensor earth horizon 1 working in the infrared range, belonging to a satellite placed on the earth orbit, given that the opposite edges of the earth emerge of the various heat (an abnormality of the earth), the earth horizon sensor 1 forming a signal of the derivative, which constitutes a measurement for the angle of the derivative of the line of referred of the earth horizon sensor with respect to the line joining the satellite - center of the earth and is used for the regulation of the position of the satellite, this signal of the latter being corrected as a function of the anomaly of the earth. / p & & p & is damped or amplifies the signals of the earth horizon sensor which may be attributed has an edge of the earth, a temperature which is greater, and those which can be attributed to the edge remote from the earth at lower temperature, as a function of a correction signal which takes account of the anomaly, in preferred manner to eliminate the amplitude variations of the signal of the precursor, caused by the anomaly of the earth.
