Aerospace Instrument-Making Annotation << Back ON THE PROBLEM OF MOTION DETERMINATION OF SPACE VEHICLE BY TRAJECTORY MEASUREMENTS A.S. Deyatisil’niy, D.E. Kislov The case of full indefinite of force causes motion of space vehicle is studied. The approach for guarantee estimation correctness of mathematical state the problem and its solution are proposed. Results of numerical experiments are presented. Keywords: space vehicle, trajectory, orbit, ground-based observation point, matrix, spectral portrait. E-mail: devyatis@iacp.dvo.ru
