Analysis of the Influence of Space Weather Factors on the Telemetry Parameters of Small Spacecraft in Low Earth Orbit

Abstract

The paper shows that high solar activity and the associated increased geomagnetic disturbance have a significant impact on the functioning of small spacecraft (SSC) in low Earth orbit (LEO). An increase in the number of anomalies in the telemetry data of small satellites with an increase in the absolute value of the geomagnetic activity index Dst is studied. The influence exerted by space weather (SW) factors on the current state of the SSC systems is also studied. An increasing dependence between the spacecraft parameters and changes in geomagnetic activity is shown, which intensifies in the subpolar regions of the orbit.
