I would like to thank ITU-pSAT II project team including Emre Koyuncu, Melahat Cihan, Elgiz Başkaya and Soner Işıksal for being my project teammates. Also, my sincere thanks goes to Control and Avionics Lab's fellow labmates, including, but not limited to, Serdar Ateş, Oktay Arslan and Nazım Kemal Üre. A special thanks goes to TÜBİTAK. Without their contributions, this project would not be possible. I would like to thank Bahadır Armağan for his support in most of the projects at Control and Avionics Laboratory. Finally, I want to thank my family. They were always behind me in good and bad days.
