Özet:

 This study presents an investigation of the positioning performance of the Real-Time Precise Point Positioning RT-PPP technique based on low-cost Global Navigation Satellite Systems GNSS observations and the contribution of multi-GNSS observations to the method. In the study, two different experiments were performed in static and kinematic modes employing two low-cost u-blox ZED-F9P receivers and ANN-MB-00 antennas. In both experiments, RT-PPP solutions were performed using the products obtained from the real-time precise orbit and clock corrections from the IGS03 stream based on Global Positioning System GPS and GPSGalileo observations, and these results were compared with the Real-Time Kinematic RTK data based on GPSGalileo observations. The findings of the experiment realized in static mode clearly demonstrated that the multi-GNSS observations converge about 30 minutes earlier than GPS-only observations and provide approximately 3, 11, and 6 cm more precise position accuracy for the east, north, and up components, respectively. The kinematic test results indicated that the multi-GNSS observations improved the position accuracy obtained compared to a single system by 33 and 25 for horizontal and vertical components, respectively. However, considering that the results obtained from both experiments are in the order of dm, it is clear that the RT-PPP technique based on low-cost GNSS observations will not be sufficient in geodetic applications that require high accuracy, whereas it provides sufficient accuracy for navigation applications.

 Bu çalışma, düşük maliyetli Küresel Uydu Navigasyon Sistemi Global Navigation Satellite Systems -GNSS- gözlemlerine dayalı Gerçek-Zamanlı Hassas Nokta Konum Belirleme Real-Time Precise Point Positioning -RT-PPP- tekniğinin konum belirleme performansının araştırılmasını ve yönteme çoklu-GNSS gözlemlerinin katkısını sunmaktadır. Çalışmada, iki adet düşük maliyetli u-blox ZED-F9P alıcısı ve ANN-MB-00 anteni kullanılarak statik ve kinematik modda iki farklı deney gerçekleştirilmiştir. Gerçekleştirilen iki deney setinde de Küresel Konum Belirleme Sistemi Global Positioning System -GPS- ve GPSGalileo gözlemlerine dayalı olarak IGS03 akışından elde edilen gerçek-zamanlı hassas yörünge ve saat düzeltmelerinden elde edilen ürünlerle RT-PPP çözümleri gerçekleştirilmiş ve bu sonuçlar, GPSGalileo gözlemlerine dayalı Gerçek-Zamanlı Kinematik Real-Time Kinematic -RTK- verileri ile karşılaştırılmıştır. Statik modda gerçekleştirilen deneyin bulguları, çoklu-GNSS gözlemlerinin sadece-GPS gözlemlerine kıyasla yaklaşık olarak 30 dakika daha erken yakınsadığını ve sağa, yukarı ve h bileşenleri için sırasıyla 3, 11 ve 6 cm mertebesinde daha hassas konum doğruluğu sağladığını açıkça göstermektedir. Kinematik deney sonuçları ise çoklu-GNSS gözlemlerinin tek sisteme kıyasla elde edilen konum doğruluğunu yatay ve düşey bileşenler için sırasıyla 33 ve 25 oranında iyileştirdiğini ifade etmektedir. Ancak, her iki deneyden elde edilen sonuçların dm mertebesinde olduğu göz önüne alındığında, düşük maliyetli GNSS gözlemlerine dayalı RT-PPP tekniğinin yüksek doğruluk gerektiren jeodezik uygulamalarda yeterli olmayacağını, buna karşılık navigasyon uygulamaları için yeterli doğruluk sağladığı açıktır.
