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

Özet

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.
