METHOD FOR IDENTIFYING IN A PRE-ESTABLISHED CATALOGUE STARS DETECTED BY A STAR SENSOR

摘要

The invention concerns the identification of stars. It consists in selecting "detected stars" among the sensed stars; coupling the detected stars; selecting all or part of the doublets of the catalogue which are most likely to have been present in the visual field of the sensor, said likely doublets and their stars constituting a set D; pairing stars of D with detected stars, and supplying all or part of the paired couples of stars to the processing system. Said method is characterised in that it comprises at least the consolidating classification of the set D stars and at least a step using this classification for reducing the number of stars to be paired and/or for carrying out the pairing, and/or for selecting the paired couples. The invention is applicable in particular for determining the attitude of an aircraft or submarine.
