News Academy of Engineering Sciences A.M. Prokhorov Annotation << Back From the history of the development of navigational display and the ability to use the experience of their use in manned flight to the Moon А.Т. MITIN, А.А. MITINA Discusses the possibility of on-board navigational display facilities to produce images of the surface of the Earth and the sky, close to the observed real Cosmonaut flight. Disadvantages and advantages of onboard navigation information display facilities are analysed. It is offered to use a slanting (orbital) equidistant cylindrical projection, mapping a plane which is perpendicular to the plane of the orbit of the spacecraft for creating a navigational display facilities. If electronic means of displaying the navigation conditions will be offset by the angular velocity of the rotation of the earth around its axis and the precession of the plane of the orbit of the spacecraft, the image seen an astronaut during a space flight, will be virtually identical to the image on the side display navigational tool that will significantly improve the working conditions of astronauts during navigation. Key words: manned space flight, onboard navigational display facilities, the image of the surface of the Earth and the sky, map projections, under satellite point, track flight of spacecraft, the spaceman navigation problems, manned flights to the Moon and other planets Contacts: Е-mail: A.Mitina@gctc.ru Pp. 08-14.
