Unlocking the secrets GNSS Satellite Orbits: the breakthroughs behind IGS Repro3 for ITRF2020
06-10-2023
In our study, we describe the quality of GNSS satellite orbits provided by individual analysis centres and combination orbits provided by the International GNSS Service Analysis Centre (IGS ACC) coordinator at Geoscience Australia. The quality of the combined orbit products has been verified using satellite laser observations. On this basis, we discussed the current developments and challenges in modelling GNSS orbits and summarised the GNSS community open issues in mulit-GNSS combination orbits.
The first half of 2023 was very fruitful for the UPWr SpaceOS Remote sensing team, part of the Institute of Geodesy and Geoinformatics at UPWr, in the view of enhancing international collaboration with one of the leading European Universities. Within the frames of the Horizon 2020 project GATHERS, three internships have been accomplished at the project’s partner headquarters at the Technical University of Delft (TU Delft), Netherlands. Dr Kamila Pawłuszek-Filipiak, the PhD student Natalia Wielgocka and the student in the Master’s program “Geodesy and Cartography” Michalina Paszek, had the chance to work with the prominent scientists prof. Ramon Hanssen and Dr Freek van Leijen and their team from the Department of Geoscience and Remote sensing at TU Delft.

2nd GATHERS Summer School in TU Delft, Netherlands - registration still open!
02-06-2023
Summer School 2023 of the Twinning Project “GATHERS – Integration of Geodetic and imAging TecHniques for monitoring and modelling the Earth's surface defoRmations and Seismic risk” will be held from August 28 th to September 1 st 2023, hosted by Delft University of Technology (TUDelft), the Netherlands. Department of Geoscience and Remote Sensing at Delft University of Technology will host a 2nd GATHERS Summer School in the last week of August 2023. The School topics will assemble theoretical and practical aspects in surface deformation monitoring built on the three main Earth’s observing methods explored within the GATHERS project:
The IGG is pleased to invite you to a scientific seminar, which will be held remotely using the Zoom platform. The presentation entitled "The application of inter-satellite links in orbit determination of GNSS satellites: simulation studies" will be given by Dr. Tomasz Kur from our institute.
The seminar will begin on Thursday 25 May 2023 at 09:00 AM (CEST).
