Mutlak konum çözüm yaklaşımı sunan MAGIC-GNSS ile CSRS-PPP ve bağıl konum çözüm yaklaşımı sunan AUSPOS ile OPUS çevrimiçi değerlendirme servislerinin, farklı gözlem sürelerindeki (1, 2, 3, 6, 12, 24 saat) ve farklı günlerdeki (DOY 048, 049, 050, 051, 052, 053/2019) verileri dikkate alınarak test edilmiştir. Bu amaçla AJAC IGS istasyonu, ITRF 2014 referans sisteminde ölçü epok koordinat verileriyle karşılaştırılmış ve elde edilen sonuçlara göre 3 saat üstü yapılan veri çözümlerinde mm doğruluğuna ulaşılmıştır. 3 saat ve altı veri çözümlerinde gerek kadastral çalışmalarda gerek birçok ölçme uygulamalarında kullanılabilecek, cm doğruluğunda çözüm sundukları görülmüştür. Mutlak konum ve bağıl çözüm yaklaşımı sunan çevrimiçi değerlendirme servislerinin yüksek doğrulukta sonuçlar elde edebildiği ve bütün çevrimiçi GNSS değerlendirme servisleri ile kolay, ekonomik ve doğru konum üretebilmenin mümkün olduğu gözlemlenmiştir.</p></abstract>
