Abstract
Bu çalışmada bir alçak yörünge uydusunun kinematik ve dinamik denklemleri elde edilerek döngüsel hareket için matematiksel model oluşturulmuştur. Kepler parametreleri kullanılarak bu alçak yörünge uydusunun yörünge hareket modeli elde edilmiştir. Döngüsel hareket modelden elde edilen yönelim bilgilerine gürültü eklenerek yönelim sensör verileri üretilmiştir. INS/GPS entegre navigasyon yapısı için sistem ve ölçüm modelleri elde edilerek farklı sensörlerden alınan yönelim bilgileri birleştirilmiştir. Sensör veri birleştirmede genişletilmiş Kalman filtre algoritmaları kullanılmıştır. Kestirilen yönelim bilgisi ile ölçülen ve gerçek yönelim bilgisi karşılaştırılmıştır. Sonuçlardan kestirilen yönelim bilgisinin gerçek yönelim bilgisine en yakın değer olduğu gözlemlenmiştir. Tüm çalışma MATLAB/Simulink ortamında gerçekleştirilmiştir.

Abstract
In this study, the mathematical model of attitude motion is obtained for low orbit sattelite (LEO) with its kinematic and dynamic equations. The mathematical model of orbit motion for LEO satellite is obtained using Kepler parameters. Sensor data are generated adding zero mean Gaussian noise to data comes from model response. These measurement data are fused using INS/GPS integration structure. Extended Kalman filter algorithm is used to sensor fusion. Compare the estimated data comes from extended Kalman filter and the actual data generated from mathematical model. It has been observed from the results that the estimated data is closest to the actual attitude data. All study is performed at the MATLAB/Simulink environment.
