The objective of this workshop is to present research activities concerning Earth-space radiowave propagation. It will address the following applications: NTN (Non Terrestrial Networks including mega-constellations), mobile communications for 5G and 6G, GNSS (Global Navigation Satellite Systems), remote sensing and radio-occultation. The targeted frequency bands range from HF to EHF, that is from 3 MHz to 300 GHz. Issues related to standardization, e.g. for ITU-R (International Telecommunications Union – Radiocommunications sector) and new frequency ...
