Abstract

In addition to the legacy GPS and GLONASS, a new global emerging system, European Galileo became operational for positioning, timing, and navigation purposes. In this study, the contribution of the Galileo constellation to GPS+GLONASS combined single point positioning (SPP) is investigated. A one-week of data in 2019 (DOY: 274-280) and 25 IGS-MGEX stations are chosen to conduct GPS+GLONASS and GPS+GLONASS+Galileo SPP. The results indicate that average Root Mean Square Errors (RMSE) of northing, easting and, up components are improved by 11%, 16%, and 4%, respectively. It is also observed that maximum errors of GPS+GLONASS SPP are significantly reduced when adding Galileo constellation.

Özet

İlk olarak ortaya çıkan küresel GPS ve GLONASS'a ek olarak, Avrupa Galileo uydu sistemi konumlandırma, zamanlama ve navigasyon amacıyla faaliyete geçtmiştir. Bu makalede, Galileo navigasyon uydularının GPS + GLONASS kombine tek nokta konumlandırmasına (SPP) katkısı incelenmiştir. GPS + GLONASS ve GPS + GLONASS + Galileo SPP değerlendirmeleri için 2019'daki bir haftalık veri (DOY: 274-280) ve 25 IGS-MGEX istasyonu seçilmiştir. Sonuçlar, kuzey, doğu ve yukarı bileşenlerin ortalama Karasel Ortalama Hatalarının (RMSE) sırasıyla %11,%16 ve %4 oranında iyileştirildiğini göstermektedir. Ayrıca, GPS+GLONASS SPP değerlendirmelerine ait maksimum hataların, Galileo uyduları eklendikten sonra ciddi oranda azaldığı gözlemlenmiştir.
