Attitude determination algorithms based on Kalman filter are considered in the paper. The algorithms processes measurements of a star sensor, gyro, magnetometer and sun sensor. Quaternion and angular velocity vector are choosen as a state vector, and for a several algorithms also biases of magnetometer and gyro measurements are also estimated. The algorithms are investigated with parameters of the 'TabletSat-Aurora' microsatellite.
