Enabling ambiguity resolution in CSRS‐PPP

open access: yesNAVIGATION, 2021
Precise point positioning (PPP) uses precise satellite orbits, clock corrections and biases derived from a global network of reference stations to enable accurate positioning worldwide. Natural Resources Canada’s Canadian Spatial Reference System (CSRS) PPP is a free Web service offering automated PPP processing. A critical factor limiting the adoption

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.

Precision measurement of the speed of propagation of neutrinos using the MINOS detectors [PDF]

open access: yes, 2015
We report a two-detector measurement of the propagation speed of neutrinos over a baseline of 734 km. The measurement was made with the NuMI beam at Fermilab between the near and far MINOS detectors.

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

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.

Performance Assessment of PPP-AR Positioning and Zenith Total Delay Estimation with Modernized CSRS-PPP

open access: yesArtificial Satellites, 2021
Abstract The precise point positioning (PPP) method has become more popular due to powerful online global navigation satellite system (GNSS) data processing services, such as the Canadian Spatial Reference System-PPP (CSRS-PPP). At the end of 2020, the CSRS-PPP service launched the ambiguity resolution (AR) feature for global positioning
