“…In this case, the estimation procedure is reduced to performing operations on sets in order to construct so-called information sets that are guar-anteed to contain the estimated values. In this work, the modification [44,45] of ellipsoidal estimation algorithms [9,12,14,29,42,48,55,56] was used. The main advantages of the modification are the minimum of a priori information about uncertain quantities, the high convergence rate, its applicability to nonlinear systems, and resistance to possible violations of a priori hypotheses about the values of uncertain quantities.…”

“…One of the approaches aimed at reducing the computational complexity of solving estimation problems is to use the ellipsoid method [9,12,14,29,42,48,55,56]. In accordance with this method, the set k X is considered to be an ellipsoid…”

“…А heuristic approach proposed in [44,45], makes it possible to reduce the amount of calculations when constructing a sequence of ellipsoidal estimates, significantly increase the rate of convergence, and also make the estimation algorithm robust with respect to violations of a priori assumptions on the properties of uncertain values. A similar approach was previously proposed and studied in [55,56]. According to approach [45], the ellipsoid…”

“…The ellipsoidal estimation method is sensitive to the violation of a priori assumptions about the value of uncertain quantities. To withdraw this property, i.e., to ensure the robustness property, several modifications of this method have been proposed [44,45,55,56].…”

In this work, we consider the problem of determining parameters of the relative motion of a non-cooperative spacecraft (NSC), which is in free uncontrolled motion, based on the results of measuring the distance to this vehicle and its attitude quaternion. The measurements are assumed to be made by some computer vision system (CVS). A specific type of СVS is not considered. It is supposed the CVS measures the distance and attitude of the so-called graphical reference frame rigidly fixed on the NSC. The parameters of relative motion include the distance vector to the center of mass (c.m.) of the NSC, the attitude quaternion of the principal inertia axes of the NSC relative to the CVS reference frame, the attitude quaternion of the graphical reference frame relative to the NSC principal reference frame, the ratio of the inertia moments, the position vector of the c.m. in the graphical reference frame. The problem is solved using a dynamic filter based on the ellipsoidal estimation method. The method implies knowledge of the maximum values of the measurement noise only, the stochastic noise characteristics are not assumed to be known and therefore are not used. The properties of the proposed algorithm have been demonstrated using numerical simulations. The results obtained are supposed to be used in the development, creation, and testing of a navigation system for the rendezvous and docking of a service spacecraft, developed by a group of enterprises in the space industry of Ukraine under the leadership of the Limited Liability Company “Kurs–Orbital”.

“…It is called a guaranteed or minimax approach to control under uncertainty. Control algorithms created on its basis require less a priori information on the properties of uncertainties and are less critical to their difference from actual properties [19][20][21]. They can remain serviceable in situations where the above-mentioned algorithms fail (diverge).…”
