New scientific project at IGG

National Science Centre has announced the laureates of OPUS and PRELUDIUM contests. We are pleased to inform that two project proposals prepared by members of the Institute of Geodesy and Geoinformatics have been awarded grants.

In the frame of the OPUS 15 under the supervision of Krzysztof Sośnica will be realized the project: “Determination of Global Geodetic Parameters using the Galileo Satellite System” whose total cost is 998 860 PLN

In the frame of the PRELUDIUM 15 under the supervision of Grzegorz Bury will be realized the project: “Precise orbit determination of GNSS satellites using combined optical and microwave solutions” whose total cost is 195 000 PLN

Sincere congratulations!

New publication on Galileo satellites

Today, a new article in Journal of Geodesy has been published concerning the Galileo constellation, including the satellites launched accidently into highly eccentric orbits: “Validation of Galileo orbits using SLR with a focus on satellites launched into incorrect orbital planes”. The article has been published as on Open access and can be downloaded from the Springer website:

Prestigious START stipend awarded to Karina Wilgan

One of our team member, Karina Wilgan was awarded prestigious START stipend from Foundation for Polish Science, “Supporting the best, so that they can become even better”. This award is handed in recognition of exceptional research performance in geodesy and cartography. Karina’s research is linked with GNSS positioning and troposphere modelling. This year over 100 stipends where awarded. Congratulations!


We are very pleased to inform that on the basis of the decision of the International Laser Ranging Service (ILRS) Governing Board and the ILRS Analysis Standing Committee, our Institute officially gained a status of the ILRS Associate Analysis Center. We provide operational products based on the microwave and laser observations to new GNSS systems, such as GLONASS, Galileo, BeiDou and QZSS. The results are available in the on-line service:

New JGR publication

A new publication co-authored by our member appeared in Journal of Geophysical Research: Atmospheres on 2nd March, 2017. The paper is entitled “An evaluation of real-time troposphere estimation based on GNSS precise point positioning” by Ding et al. This work covers the issue connected with the real-time GNSS meteorology improvement using multi-GNSS observations. An operational real-time system for zenith troposphere delay estimation was established in the paper. The presented system uses a modified version of PPP-wizard software. The results show that the ambiguity resolution improves the accuracy of ZTD while initialization time is shortened by GNSS observations. The full bibliography note can be found in the publications tab. We wish you a pleasant and informative reading!


The first place in the JUNIORSTAV 2017 Conference.

On 26 January 2017, at Brno University of Technology (Czech Republic), took place the 19th International Conference of Postgraduate Students, JUNIORSTAV 2017. The paper of authorship of Grzegorz Bury, “Comparison of GNSS orbits determined using microwave and optical observations” took the first place in section Geodesy, Cartography and GIS .

The work realised in the frame of the doctoral thesis considers the determination of GNSS orbits using Satellite Laser Ranging observations. The author presented the methodology of the determination of GNSS orbits using optical data and the first results obtained from modified version of Bernese GNSS Software 5.2. Presented results show the improvement in the consistency of solutions based on microwave (GNSS) and optical (SLR) data.

In the JUNIORSTAV 2017 participated also Mateusz Drożdżewski and Agata Walica from Institute of Geodesy and Geoinformatics.
