Abstract
Son yıllarda GNSS
alıcılarının konumları, Network RTK yaklaşımı ile referans istasyonlarının
gözlemleri ve farklı düzeltme teknikleri kullanılarak hesaplanmaktadır. Network
RTK yaklaşımı ve düzeltme yöntemlerinin kullanımı üzerine günümüzde çalışmalar
devam etmektedir. Yıldız Teknik Üniversitesi (YTU) Davutpaşa Kampüsünde
gerçekleştirilen bu çalışmada, aynı bölgede birbirine yakın gökyüzü ile farklı
görüş açısına sahip test noktaları seçilmiştir. İstanbul’u kapsayan İSKİ
Network RTK Ağından veri aktarma yöntemleri kullanılarak nokta konum bilgileri
elde edilmiştir. Bu makalenin amacı, Ağ RTK ile farklı düzeltme yöntemlerine
göre farklı nokta konumları için Multipath etkisi ve farklı taşıyıcı faz
başlangıcı belirsizliği çözümlerine göre elde edilen nokta konumlarını (X, Y,
h), aynı noktaların Statik GNSS ve Total Station ile elde edilen nokta
konumları ile karşılaştırmaktır. Düzeltme yöntemlere göre elde edilen
istatiksel değerler incelendiğinde sonuçlar birbirine yakın fakat nokta
konumuna, sinyal yansıma giderici etkisine ve taşıyıcı faz başlangıç çözümüne
göre Statik GNSS ve yersel ölçüler ile cm düzeyinde farklılık göstermektedir.

Abstract
In recent years,
Location of GNSS receivers are calculated using observations of reference
stations with Network RTK approach and the different correction techniques
Today, studies on the use of network RTK approach and correction methods
continues. Test points are selected with the different viewing angle as the sky
close to each other in the same area in this study performed at the Yıldız
Technical University (YTU) Davutpasa Campus. The point location information is
obtained using data correction methods from ISKI CORS Network covering
Istanbul. The aim of this article, the point position (X, Y, h) obtained by
multipath effect and different ambiguity solutions according to methods of
different correction with Network RTK for different point locations is to
compare with point locations obtained with static GNSS and Total Station of the
same points. When the statistical values obtained according to the correction
methods are examined results are close to each other, but it differs cm level
with static GNSS and terrestrial measurements according to point position,
multipath effect and ambiguity solution
