Abstract

In terms of providing high accuracy, low cost due to use of single GNSS receiver and ease of use, Precise Point Positioning (PPP) method has increasing interest day by day. In addition, since the GLONASS reached full capacity like GPS, and both system could be used together, this provide positive influence on the Precise Point Positioning applications. In this study using GPS and GPS/GLONASS observation data, a comprehensive statistical evaluation of static observation data was made using PPP results. Evaluation process was performed with 4 IGS stations at different latitude regions by using short (1h, 3h) and long (6h, 12h, 24h) observation durations. The results obtained in the long observation period showed that differences between GPS and GPS/GLONASS results were not significant in terms of accuracy and repeatability. For the short observation periods, particularly 1 hour, GPS/GLONASS gives better results.

Özet

Yüksek doğruluk sağlaması, tek GNSS alıcısı kullanıldığı için maliyetinin düşük olması ve kullanımının kolay olması nedeniyle Hassas Nokta Konumlama (PPP) yöntemine olan ilgi her geçen gün artmaktadır. Ayrıca GPS'in yanı sıra GLONASS'ın da tam kapasiteye ulaşması ve bu iki sistemin birlikte kullanılabilir olması Hassas Nokta Konumlama uygulamalarına olumlu etki sağlamaktadır. Bu çalışmada GPS ve GPS/GLONASS gözlem verileri kullanılarak statik PPP sonuçlarının kapsamlı bir istatistiki değerlendirmesi yapılmıştır. Değerlendirme işlemi farklı enlemlerdeki 4 IGS noktasına ilişkin kısa (1s, 3s) ve uzun (6s, 12s, 24s) gözlem süreleri kullanılarak gerçekleştirilmiştir. Elde edilen sonuçlar uzun gözlem sürelerinde GPS ve GPS/GLONASS sonuçlarının arasındaki farkların doğruluk ve tekrarlılık bakımından anlamlı olmadığını göstermiştir. Kısa gözlem sürelerinde ve özellikle 1 saatlik çözümlerde ise GPS/GLONASS daha iyi sonuç vermektedir.
