| Zusammenfassung |
| A large database of anomalies, registered by 220 satellites
in different orbits over the period 1971-1994 has been compiled. For the
first time, data from 49 Russian Kosmos satellites have been included in
a statistical analysis. The database also contains a large set of daily and
hourly space weather parameters. A series of statistical analyses made it
possible to quantify, for different satellite orbits, space weather
conditions on the days characterized by anomaly occurrences. In particular,
very intense fluxes (>1000 pfu at energy >10 MeV) of solar protons are
linked to anomalies registered by satellites in high-altitude
(>15000 km), near-polar (inclination >55°) orbits typical for navigation
satellites, such as those used in the GPS network, NAVSTAR, etc. (the rate of anomalies
increases by a factor ~20), and to a much smaller extent to
anomalies in geostationary orbits, (they increase by a factor ~4).
Direct and indirect connections between anomaly occurrence and geomagnetic
perturbations are also discussed. |
