7 June 1996 IR horizon sensor based on multielement pyroelectric detector
Author Affiliations +
One of the basic claims for new-developed opto-electronic devices intended for attitude control of space vehicles is the mass and dimensions minimizing with preservation of high accuracy and reliability. Novel Earth horizon sensor for the 2-axis oriented vehicles is developed, based on 4 pyroelectric arrays, that are obturated by the 4-slits modulator. Such sensor can be used for precision measuring of the satellite attitude angles. The sensor is protected against the Sun and the Moon interference. It can be modified for any orbit altitude.
