Abstract This paper introduces the concept of attitude determination, the method for attitude expression and means of attitude determination, and then attitude determination algorithms based on two baselines are presented. In order to investigate the calculating quality with the three algorithms in different conditions, the simulation data is divided into eight cases on the basis of ratio precision of the two baselines. Through the analysis of the computation accuracy of the attitude angles, the cost function and the computation time with the three algorithms in different cases, we found out that the computation results with the optimized TRIAD algorithm and the QUEST algorithm are exactly the same, the cost function decreases with the reduction of precision ratio of the two baselines, the precision of attitude angle is inconsistent with the variation of the cost function, the computation time with TRIAD algorithm is less than those with the other two algorithms.
