Abstract
Attitude determination using vector observations and the related Adaptive Optimal-REQUEST algorithm are studied. Analysis of Optimal-REQUEST´s characteristic is listed. In the condition that the observe noise changes frequently, improved adaptive method is imported. The model noise is estimated real-timely and it is used in the updating of states. The simulation indicated that the algorithm could effectively estimate the noise of observation and improve the precision of attitude determination.
