Aerospace Instrument-Making Annotation << Back NAVIGATION AND HOMING BY SPATIAL GEOPHYSICAL FIELDS G.I. Dhzandzhgava, L.I. Avgustov The following is viewed in the paper: 1) the achieved state in solving problems of navigation and homing by earth magnetic field (EMF), earth gravitational field (EGF) and earth electromagnetic field (EEMF) on the basis of results of research effort performed in 2000–2007 by JSC «RDC» together with other companies and 2) readiness to their practical realization. The state with readiness for realization of five navigation and homing systems with regard to generation of banks containing cartographic information on spatial fields and airborne sensors of these fields is view. Key words: correlated-extreme navigation, magnetic field, gravitational field, earth electromagnetic field, banks containing cartographic information. Contacts: E-mail: L_Avgustov@rpkb.ru Pp. 58-66.
