Directory of engineer Annotation << Back Working Out of a Ground Data Treatment Model of Preparation of Flight Data for Synthetic Vision Systems Sazonova T.V., Shelagurova M.S. There are considered the problems of ground data treatment for Synthetic Vision Systems in the article. Loading of initial data, their converting in onboard structures and formats, and also verifi cation of the received data in 3D mode concern such problems. Necessary onboard data for visualization in the Synthetic Vision System is matrix of district height, object structure, aeronavigation information. Also initial data, such as digital vector maps of SXF format, the aeronavigation information in the form of a text fi le of ARINC 424 format, the text description of object structure are investigated in the article. Structures, formats, expansions of the initial and onboard information for correct functioning of a ground data treatment are presented. Besides, the list of the necessary program modules of a ground data treatment, completely satisfying to complex tasks in view, has been generated. Keywords: Synthetic Vision System, runways, vector maps, aeronavigation information, matrix of district height, objects structure, ground data treatment, conversion, board format, board data structure.
