Aerospace Instrument-Making Annotation << Back Optimization of definition process of a magnetic field induction vector onboard a mobile ferromagnetic object V.A. Tikhonov, V.E. Plekhanov, A.I. Chernomorsky, V.N. Maksimov An approach of the definition of the induction background magnetic field vector onboard the moving ferromagnetic object based on model built using a Puasson matrix is suggested. The components of the vector are defined in axes connected with the object using the information about it angular orientation from the inertial system. To raise the accuracy of the assessment of the model’s parameters the optimization of the process of the angular orientation change of the moving object on its trajectory is represented. The algorithms of the models characteristics assessment and optimization of the angular orientation are offered, the results of the numerical experiment proving the effectiveness of the approach are given.
