Özet
This study investigates the effects of magnetic disturbances resulting from geospace storms on the satellite attitudes estimated by EKF. It is shown that the increasing levels of geomagnetic activity affect geomagnetic field vectors predicted by IGRF and T89 models. Various sensor combinations including magnetometer, gyroscope, and sun sensor are evaluated for magnetically quiet and active conditions. Errors are calculated for estimated attitude angles and differences were discussed. This study emphasizes on the importance of environmental factors on the satellite attitude determination systems.

Zerefsan Kaymaz currently works as a full professor at İstanbul Technical University, Faculty of Aeronautics and Astronautics. She received her PhD from Department of Atmospheric Sciences at UCLA. She studied as a researcher in Boston University, Max Planck Institute for Aeronomy, APL, and NASA/GSFC Space Weather Laboratory. She received Alexander von Humbolt fellowship, and TÜBİTAK Young Scientist award in Upper Atmosphere and Space Physics in Turkey. Her research is focused on Space Environment and its effects on Satellites. She acts as a referee in international journals and evaluator in European Union projects. She is a member of AGU, COSPAR, IAA. Demet Cilden-Guler received her BSc and MSc from Istanbul Technical University in 2014, and 2016 respectively. She is currently a PhD candidate at Aeronautical and Astronautical Engineering Department, Istanbul Technical University. She is the author/coauthor of 30 conference and 9 SCI journal papers. She is supported by ASELSAN (Military Electronic Industries) and TUBITAK (Scientific and Technological Research Council of Turkey) PhD Scholarships. She is one of the 2018 Amelia Earhart Fellows. Her professional interest areas are Kalman filtering, attitude determination and control of small satellites, extraterrestrial magnetic field and planets' albedo effects on satellite's attitude, and integrated estimation methods. D. Cilden-Guler is supported by ASELSAN and TUBITAK PhD scholarships. We communicated with Dr. Nikolai Tsyganenko at Saint-Petersburg State University for the most updated version (T89d) of the Tsyganenko models.
