Estimation of parameters of two coupled maneuvers performed by an active space object

Abstract

The paper is devoted to the problem of estimating the parameters of two maneuvers performed by an active space object between two successive sessions of measurements, which is very important for the maintenance of the catalog of space objects. The parameters of coplanar and noncoplanar impulse and long-duration maneuvers are determined. An advantage of the proposed method is the high speed of estimation, unattainable in traditional approaches, and simplicity of program implementation, because the solution of each problem depends upon the solution of the preceding, simpler problems.
