“…The results of [1,3,6,18,20,30], which indicate the efficiency of using such control algorithms, have been confirmed. However, when using the "-Bdot" algorithm, it is necessary to accurately estimate the components of the magnetic field induction vector of our planet [19]. For this algorithm, it is necessary to study the operation of measuring instruments in conditions of dense location and under the influence of the equipment operation to ensure the functioning of the spacecraft, including the executive bodies, the target equipment of the spacecraft [32].…”

“…Thus, reducing the angular velocity of the rotational motion of a small spacecraft is an important and urgent modern task. The paper considers the use of the well-known -Bdot algorithm [18,19] to reduce the angular velocity of rotation for a small spacecraft without large elastic elements. It is assumed that the spacecraft is operated in nonorientated flight.…”

This article considers the issues of reducing the angular velocity of rotation for a small spacecraft operated in uncontrolled flight. A mathematical model based on Euler’s dynamic equations in the main coupled coordinate system of a small spacecraft has been constructed. The transition of the inertia tensor of the Aist small spacecraft pilot model from the bench coordinate system to the main connected coordinate system was performed. A study and evaluation of the significance of various disturbing factors in modeling the rotational motion of a small spacecraft around the center of mass has been carried out. At the same time, gravitational, aerodynamic and magnetic disturbing factors are considered. The application of the -Bdot algorithm by magnetic executive bodies to reduce the angular velocity has been studied. Results are obtained demonstrating the effectiveness of the -Bdot algorithm application on the example of the Aist small spacecraft pilot model. The results of the presented work can be used in the development of effective algorithms for controlling the movement of a small spacecraft around the center of mass in order to reduce the angular velocity of its rotational motion.

The paper considers the issues of reconstruction of the power disturbing effect on the prototype of the small spacecraft "Aist". The measurements data of the components of the induction vector of the Earth's magnetic field by means of two three-component magnetometers were used for the reconstruction. The obtained results can be used to assess microaccelerations in the internal environment of small spacecraft, as well as to study their uncontrolled rotational motion.
