This review paper presents research results on geodetic positioning and applica-tions carried out in Poland, and related to the activities of the International Association ofGeodesy (IAG) Commission 4 “Positioning and Applications” and its working groups. Italso constitutes the chapter 4 of the national report of Poland for the International Union ofGeodesy and Geodynamics (IUGG) covering the period of 2015-2018. The paper presentsselected research, reviewed and summarized here, that were carried out at leading Polishresearch institutions, and is concerned with the precise multi-GNSS (Global NavigationSatellite Systems) satellite positioning and also GNSS-based ionosphere and tropospheremodelling and studies. The research, primarily carried out within working groups of theIAG Commission 4, resulted in important advancements that were published in leadingscientific journals. During the review period, Polish research groups carried out studies onmulti-GNSS functional positioning models for both relative and absolute solutions, stochas-tic positioning models, new carrier phase integer ambiguity resolution methods, inter systembias calibration, high-rate GNSS applications, monitoring terrestrial reference frames withGNSS, assessment of the real-time precise satellite orbits and clocks, advances in tropo-sphere and ionosphere GNSS remote sensing methods and models, and also their applica-tions to weather, space weather and climate studies.
