Abstract

This study is to investigate the effects of various solutions of GPS only, GLONASS only, and combined GPS/GLONASS observations under different elevation angles on different GNSS days by using Magic GNSS software. Different elevation angles and measurement days were considered to investigate the increasing or decreasing number of satellites’ effects on the measurement accuracy, and positioning accuracy affected by the solutions of GPS only, GLONASS only, and combined GPS/GLONASS observations, respectively. The assessment was based on statistical tests, namely ANOVA and Post Hoc tests. A test network, consisting of all the continuous stations of the ISKI CORS network in Istanbul city, was used to fulfill the aims of the study. The results showed that significant differences between positions of points obtained by GNSS in various elevation angles and with different satellite configurations were determined. Different satellite and measurement configurations affect position accuracy. In addition, the results showed that on the 136th GNSS day, significant differences in X and Z components were found while in Y components there were no significant differences encountered. In conclusion, combined GPS/GLONASS solutions produced better results under small elevation angles of 5° 10° or 15° than the solutions of GPS-only and GLONASS-only observations.

Abstract

Bu çalışma, Magic GNSS yazılımı kullanılarak farklı GNSS günlerinde farklı yükseklik açıları altında yalnızca GPS, yalnızca GLONASS ve kombine GPS/GLONASS gözlemlerinin çeşitli çözümlerinin etkilerini araştırmak içindir. Uydu sayısının artan veya azalan ölçüm doğruluğu üzerindeki etkilerini araştırmak için farklı yükseklik açıları ve ölçüm günleri dikkate alınmıştır. Değerlendirme, ANOVA ve Post Hoc gibi istatistiksel testlere dayanmaktadır. Çalışmanın amaçlarını gerçekleştirmek için İSKİ CORS ağının İstanbul ilindeki tüm sürekli istasyonlarından oluşan bir test ağı kullanılmıştır. Sonuçlar, GNSS ile çeşitli yükseklik açılarında ve farklı uydu konfigürasyonlarında elde edilen noktaların konumları arasında önemli farklılıklar olduğunu göstermiştir. Farklı uydu ve ölçme konfigürasyonları, konum doğruluğunu etkilemektedir. Ayrıca sonuçlar, 136. GNSS gününde X ve Z bileşenlerinde anlamlı farklılıklar bulunduğunu, Y bileşenlerinde ise anlamlı bir farkla karşılaşılmadığını göstermiştir. Sonuç olarak, kombine GPS/GLONASS çözümleri, yalnızca GPS çözümlerine ve yalnızca GLONASS gözlemlerine göre 5° 10° veya 15°'lik küçük yükseklik açıları altında daha iyi sonuçlar vermiştir.
