GNSS Gözlem Süresine Bağlı Deformasyon Parametrelerinin Kestirimi

Bu çalışmada, GNSS ölçme süresinin deformasyon parametreleri (yer değiştirme, hız ve gerinim parametreleri) üzerindeki etkisinin araştırılması ve buna bağlı olarak doğruluk ölçütlerinin belirlenmesi amaçlanmıştır. Bu amaç kapsamında, TUSAGA-Aktif ağına ait 11 GNSS istasyonunun 2012.63 – 2017.63 yılları arasındaki 6 periyot gözlem verisi ölçme süresine (4, 6, 8, 12, 24 saat) bağlı olarak Bernese v5.2 yazılımı ile ITRF-08 referans sisteminde değerlendirilip istasyonlara ilişkin deformasyon parametreleri belirlenmiştir.
