Aerospace Instrument-Making Annotation << Back CONSIDERATION OF CAPABILITY FOR DETERMINATION AND COMPENSATION OF MAGNETIC DEVIATION AT SCHEDULED FLIGHT ROUTE OF AIRCRAFT G.I. Soborov The research paper shows a capability, features and advantages arising from the combination of process for implementation of deviation operations with scheduled flight of aircraft (AC). In this case, usage of magnetic interferences in order to identify the parameters, as a mathematical basis of well-known methods regarding regression analysis complicates the implementation of the assigned task within flight route conditions. Therefore, it is proposed to apply a method for identifi cation of the interference parameters by solving scalar-matrix systems of linear equations, being generated by means of vector transformations during quite simple and few turns of aircraft around its own axes, and the ones that are being generated at variation of the Earth’s magnetic fi eld parameters in-flight. The proposed implementation for solution of deviation task at scheduled flight route by excluding any shortcomings of well-known methods, due to large amount of preliminary works and implementation of multi-step serial changes and measurements of induction vector component of the Earth’s magnetic fi eld and performed by a lot of aircraft turns and with the need to fly by composite paths, reduces high-cost facilities, demanding a lot of material, fuel and time costs. It is shown that it is necessary to select reference points at the route path, determining a required basis of prior data for generation of linear equation systems. Despite the limitations, arising due to constancy of circle and assigned fl ight path of aircraft, however, the analysis performed with the help of generating matrices of Poisson’s equations shows a wide possibility for generation of various equation systems for identification of interference parameters at aircraft flights in normal and anomalous magnetic fields. Key words: magnetic deviation, Poisson’s coefficients, deviation operations, magnetometer, magnetic interferences of movable object.
