Research on Algorithms for Multi-Vector Attitude Determination

Various attitude estimation methods are based on an optimization problem posed in 1965 by Grace Wahba, which is called Wahba’s the field of estimation. As a key for determination, many different algorithms minimizing loss function have been proposed past 60 years. Among most representative Quaternion Estimator (QUEST), Singular Value Decomposition (SVD), and Fast Optimal Attitude Matrix (FOAM), briefly introduced this research paper, new recent years such as Linear (FLAE), also included. The calculation principle derivation process given article, simulation under high noise conditions mentioned has completed. Finally, several practical engineering applications related to future development trend discussed.
