Hassas Nokta Konumlama (PPP) Tekniğinin Ağaçlık Alanlardaki Konum Belirleme Performansının CSRS-PPP Yazılımı Kullanılarak İncelenmesi [PDF]

open access: yesAfyon Kocatepe University Journal of Sciences and Engineering, 2023
GNSS teknolojisi, orman kaynaklarının araştırılması ve izlenmesi için güçlü bir araç haline gelmiştir. Ancak, ormanlık/ağaçlık alanlarda orman örtüsü GNSS sinyalleri ve uydu sayısı üzerinde olumsuz etkiye sahiptir. Bu yüzden hassas konum belirlemek mümkün olmayabilmektedir.

Reliability of CSRS-PPP for Validating the Egyptian Geodetic Cors Networks

open access: yesArtificial Satellites, 2022
Abstract The development, utilization, and maintenance of continuously operating reference stations (CORS) network are vital in many areas of surveying and geodesy, such as controlling geodetic networks, developing local ionospheric models, and estimating the tectonic plate movements. Accordingly, the Egyptian Surveying Authority (ESA)

Using PPP-GNSS Technique for Detecting Surface Motion due to Earthquake Shaking based on time-domain analysis [PDF]

open access: yesPort Said Engineering Research Journal, 2021
Many earthquakes with moderate magnitude have occurred in many areas in the world. The common procedures to extract the dynamic responses mainly depend on monitoring the change of the points in a time interval.

Studying the Fixing Rate of GPS PPP Ambiguity Resolution Under Different Geomagnetic Storm Intensities

open access: yesSpace Weather, 2023
Global Positioning System (GPS) Precise Point Positioning (PPP) with correct fixing ambiguity resolution (AR) can reach cm‐mm level positioning accuracy. However, this accuracy can be degraded by the geomagnetic storm effects.
