Aerospace Instrument-Making Annotation << Back METHOD OF DECREASE IN COMPUTING EXPENSES AT THE DECISION OF THE PROBLEM OPERATIVE ESTIMATION MODAL-PHYSICAL COORDINATES OF SPACE VEHICLES A.S. Ermilov, T.V. Ermilova, V.M. Sukhanov The modified algorithm Kalman filtration modal-physical (MP) coordinates of flexible spacecraft is offered. Thus the part of the ultra-harmonics not subject to supervision is represented as nonwhite noise in measurements. It allows due to downturn about an observable vector of a condition to lower requirements to onboard computers at preservation of required estimation accuracy. The results of mathematical modelling confirming convergence, stability and accuracy of the synthesized MP-coordinates algorithm estimation are resulted. Phone: (495) 334-87-79
