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: https://link.springer.com/article/10.1007/s00190-017-1050-x
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!
The latest newsletter of the EGSIEM (European Gravity Service for Improved Emergency Management – Horizon 2020 Project) has recently been released with a short interview with Dr. Krzysztof Sośnica, EGSIEM Associate Member.

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: http://multi-slrgnss.rhcloud.com/.
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!
We would like to invite all interested participants to the EUREF 2017 Symposium that will be held in Wroclaw, Poland, on May 17-19, 2016 (Wednesday to Friday).
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.
GNSS&Meteo welcomes 5 new members. We enrolled five young researchers:
Estera Trzcina – working on the GNSS data assimilation in Numerical Weather Models,
Elżbieta Lasota – investigating the use of Radio Occultation technique to strengthen environmental monitoring,
Iwona Kudłacik – working on the integration of control networks and GNSS,
Grzegorz Bury – improving the consistency of solutions based on optic (SLR) and microwave (GNSS) observations to the Earth’s artificial satellites,
Mateusz Drożdżewski – his field of research is troposhere delay modeling for SLR observations.
We are happy to have you on board.
GNSS&Meteo and Institute of Geodesy and Geoinformatics are seeking 4 motivated candidates to join our research team in the field of: 1) troposphere aided positioning, 2) GNSS based troposphere monitoring, 3) troposphere tomography, 4) radio occulatation.
