Аннотация: A detailed review of domestic and foreign scientific publications, dedicated to the influence of geomagnetic disturbances and powerful bursts of the Sun's radio radiation on the operation quality of satellite radio navigation systems (SRNS) and their functional additions, is performed. It is shown that existing methods of providingПоказать полностьюthe required radio navigation characteristics during operation of the SRNS user's device in the autonomous and differential modes do not fully satisfy modern requirements to SRNS in the conditions of influence of unfavorable helio-geophysical factors. A system of organization-technical measures targeted at provision of the required precision and continuity of the position determination of SRNS users under influence of geomagnetic disturbances and bursts of solar radio radiation is considered. For the practical realization of these measures an approximate structure of the complex system to provide the required characteristics of SRNS in unfavorable helio-geophysical conditions is suggested. This system may be considered as a necessary component of the perspective service of global monitoring and forecasting of the SRNS operation quality. © Allerton Press, Inc. 2009.
