                         determining the attitude on board a spacecraft, in real time and 
                         autonomously, using a star tracker system called AST (autonomous 
                         star tra cker), currently under development at the Brazilian 
                         National Institu te for Space Research - INPE. Here we describe 
                         the methods and techniques used in the development of the star 
                         trac ker system software. One of the tracker application s will be 
                         to compose the attitude control system of future Brazi lian 
                         satellites. As a result of this effort, two co mputer program 
                         packages were created. The first one is intended to control the 
                         star tracker system operation, and the other is a simulation 
                         environment to test the system operation . This simulator was 
                         called ADAST (Attitude Determi nation Algorithm Software Test). 
                         The attitude determinatio n software employs a pattern recognition 
                         procedure to identify stars in the field of view (FOV) of an 
                         active pixel sensor (CMOS APS) which comprises a star sensor sy 
                         stem of one fixed head. Only the part of the studies concerning 
                         the search and track operations, along with their results, are 
                         discussed and presented in this paper.",
