Research abstract
A NEW, PRECISION THREE-AXIS ATTITUDE DETERMINATION SYSTEM LOW-EARTH-ORBIT SPACECRAFT IS THE GOAL OF THIS PROJECT. THESUN/EARTH REFERENCE SYSTEM (SERS) USES THE SUN AND THE EARTHAS ATTITUDE REFERENCES FOR UPDATING PRECISION GYROS AND HAS THE ACCURACY POTENTIAL TO MEET THE ATTITUDE DETERMINATION AND CONTROL REQUIREMENTS OFF TODAY'S STAR TRACKER/GYRO BASEDSYSTEMS. THE UNIQUENESS OF THE APPROACH IS THE PROPOSITION THAT, WHEN EARTH SENSOR DATA ARE AVERAGED OVER A FULL ORBIT ALL SYSTEMATIC AND RANDOM EFFECTS ARE GREATLY ATTENUATED, PROBABLY TO LESS THAN .01 DEGREES. FLIGHT DATA FROM LANDSATD IS ANALYSED TO SHOW THE VALIDITY OF THIS PROPOSITION.
