ASTRO-type systems for autonomous attitude determination in space are introduced. They recognize stars which are registered in the field of view (FOV) of a star sensor by using an on- board star catalogue for subsequent attitude determination in the 2nd equatorial coordinate system. The star sensor utilizes a Peltier-cooled CCD array in the focal p...
Article
The performance of the ASTRO-1 system for autonomous attitude determination, launched on November 26th, 1989 aboard the Mir space station, is briefly discussed. The system consists of three star sensors, three image processing units, an attitude determination unit, and a manager and interface unit. Test results indicate that the in-orbit performanc...

A new version of the ASTRO-1 star sensor employed aboard the Soviet Mir orbital station is considered. New design requirements including greater stability of its measuring accuracy, improvement of reliability parameters, reduction of power consumption, weight, and volume, faster data acquisition and renewal rate, and synchronization with the spacec...
