AB  - In this study, the effects of environmental conditions at different altitudes and electromagnetic fields generated by ion thrusters on the avionic system and data transfer to the ground control station were investigated. Ion thrusters, which are used as main thrusters or side force generators in space vehicles, generate a certain electromagnetic field due to their high voltage operation and characteristic features. Other variables that pose a risk of affecting aircraft or spacecraft's data transmission are temperature and pressure. The mentioned values vary under different atmospheric conditions and within the scope of this study; pressure values between 101 kPa and 50 kPa and temperature values between 25°C and -15°C were determined as variable parameters. In order to simulate space environment for the desired temperature and pressure values, a vacuum box was used. Furthermore, the influence of the ion thruster, operated under varying voltages and excitation frequencies, was analyzed by positioning it at different distances within the vacuum chamber containing the avionics system. The avionic system send data to the ground control station for all experimental cases.

N2  - Bu çalışmada, farklı irtifalardaki çevresel koşulların ve iyon iticiler tarafından oluşturulan elektromanyetik alanların aviyonik sistem ile yer kontrol istasyonuna veri iletimi üzerindeki etkileri incelenmiştir. Uzay araçlarında ana itici ya da yan kuvvet üreteci olarak kullanılan iyon iticiler, yüksek gerilimle çalışmaları ve karakteristik özellikleri nedeniyle belirli bir elektromanyetik alan oluştururlar. Uçak ya da uzay araçlarının veri iletimini etkileyebilecek diğer değişkenler ise sıcaklık ve basınçtır. Bahsedilen bu değerler atmosferik koşullara bağlı olarak değişkenlik göstermekte olup, bu çalışma kapsamında 101 kPa ile 50 kPa arasında basınç değerleri ve 25°C ile -15°C arasında sıcaklık değerleri değişken parametreler olarak belirlenmiştir. İstenilen sıcaklık ve basınç değerlerinde uzay ortamının simüle edilebilmesi amacıyla vakum kutusu kullanılmıştır. Ayrıca, iyon iticinin farklı gerilim ve uyarma frekanslarında çalıştırılması durumunda aviyonik sisteme olan etkisi, bu iticinin vakum odasında farklı uzaklıklara yerleştirilmesiyle analiz edilmiştir. Aviyonik sistem, tüm deneysel durumlar için yer kontrol istasyonuna veri iletimi gerçekleştirmiştir.
