Book Description

The book presents the foundation and analysis of methods of application of contemporary means of astronavigation, determination of their accuracy characteristics and effectiveness. It examines the system of spherical celestial coordinates of luminaries, conditions and possible principles of their direction finding. A general equation for direction finding of a luminary by a plane from a mobile platform is obtained along with equations of direction finding of a luminary from aerodynamic and space vehicles. The cause and character of changes of coordinates of luminaries in flight are examined; a survey of systems of measurement of time used during solution of problems of navigation of aircraft is given, and astronomical methods of measurement of time are shown. A foundation for a rational method of in-flight application of aviation sextants and automatic astrocompasses is given. Possible principles of use of astronomical methods in automated complex navigational systems are examined. In an example of stellar tracker type BTs-63 the method of preparation of initial data is expounded. Means and methods of calculation and appraisal of conditions of natural illumination in flight are shown.
