Introduction：
Prof. Andrzej Krankowski is a Full Professor at the Faculty of Geodesy, Geospatial and Civil Engineering (GGCE) of the University of Warmia and Mazury in Olsztyn (UWM), Poland and a Head of Space Radio-Diagnostic Research Centre (SRRC/UWM) and Lamkówko Satellite
Observatory. He is a Member of the Governing Board of International GNSS Service (IGS) and since 2007 he is a Chairman of the IGS Ionosphere Working Group and Product Coordinator. Prof. Andrzej Krankowski is a Member of the Management Committee of COST Action ES0803: "Developing space weather products and services in Europe" and COST MP1104 „Polarization as a tool to study the Solar System and beyond"; Co-Chair of Beacon Satellite Studies Working Group of URSI Commission G; Co-Chair of URSI/COSPAR Working Group on International Reference Ionosphere (IRI). Actually he is also a Chairman of the POLFAR (POlish Low Frequency ARray) Consortium and representative of POLFAR to International LOFAR Telescope (ILT) Governing Board. During his research he especially developed new algorithms for precise modelling and forecasting of the disturbed ionosphere. The SRRC/UWM managed by him has broad expertise in research related to space weather awareness and atmosphere remote sensing with GNSS.
