The database created by us based on malfunctions of more than 300 spacecraft differently orbited from 1971 to 1994, which formed the basis for statistically analyzing the effect of the space on operation of satellites, is described.

A statistical analysis based on more than 6000 malfunctions has made it possible to obtain the quantitative characteristics of the relations between malfunctions and the space weather factors. In particular, very intense solar proton fluxes (with energy > 10 MeV) cause an almost 20-fold increase in the number of failures in high polar orbits and much weaker affect geostationary and low polar orbits. Enhanced electron fluxes (>2 MeV) increase the number of failures on geostationary and low-orbiting polar satellites but almost do not affect high-orbiting polar satellites. Direct and indirect relations between malfunctions and geomagnetic disturbance are discussed.

Abstract
The database created by us based on malfunctions of more than 300 spacecraft differently orbited from 1971 to 1994, which formed the basis for statistically analyzing the effect of the space on operation of satellites, is described. Data on 49 satellites of the Cosmos series have been included in an analysis for the first time. The database also includes the large set of daily and hourly values of the space weather parameters. A statistical analysis based on more than 6000 malfunctions has made it possible to obtain the quantitative characteristics of the relations between malfunctions and the space weather factors. In particular, very intense solar proton fluxes (with energy > 10 MeV) cause an almost 20-fold increase in the number of failures in high polar orbits and much weaker affect geostationary and low polar orbits. Enhanced electron fluxes (>2 MeV) increase the number of failures on geostationary and low-orbiting polar satellites but almost do not affect high-orbiting polar satellites. Direct and indirect relations between malfunctions and geomagnetic disturbance are discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
