Mr Jakub Białas is a second year PhD student in the field of satellite geodesy at the University of Environmental and Life Sciences in Wrocław. His research focuses on the study of satellite clocks in GNSS constellations, with particular emphasis on stochastic modelling of satellite clocks to improve the accuracy of Precise Point Positioning. In today's presentation, he will discuss his work on combining multi-GNSS clock products and their impact on the Precise Point Positioning method.

Marcin Mikoś received his Master of Engineering in Geodesy and Cartography from the Wroclaw University of Environmental and Life Sciences in 2022 and is currently a Ph.D. student. His main task includes multi-GNSS positioning with clock modeling.

Mr. Gaëtan Fayon holds an engineering degree from IMT Atlantique (2014) and a Ph.D. from the University of Toulouse (2017), both in space communication systems. After 5 years working as system integration and validation engineer in space and automotive industries in France, he joined in 2022 the European Space Agency (ESA) to work on the Galileo project. His main role today focuses on Galileo system integration, validation and qualification, but he is also involved in the Digital Transformation, supporting new processes and tools deployment in the aerospace sector.

María Crespo Estrada holds a double MSc in Aerospace Engineering by the Technical University of Madrid and Computational Software and Techniques in Engineering by Cranfield University. She has worked as an Advanced Engineer for five years in GMV in the field of GNSS high accuracy positioning with a high focus in GNSS Integrity. She is currently leading the development and integration GMV GSharp Safe and Accurate Positioning Engine in Autonomous Driving Application for automotive customers.
