Remarkable advances in recent years demonstrate that geodesy today is driven by a broad spectrum of interactions, including theory, science, engineering, technology, observations, and practice-oriented services. Geodetic science accumulates significant results in studies towards classical geodetic problems and problems that have only recently emerged or gained new interest - in many cases due to synergistic activities in geodesy and tremendous advances in instrumentation and computational tools. In-depth studies have progressed in parallel with investigations that led to a broadening of the traditional core of geodesy. Within this concept, we seek contributions concerning problems of reference frames, gravity fields, geodynamics, or positioning, but also studies surpassing the frontiers of these topics. We invite presentations discussing analytical and numerical methods in solving boundary-value or inverse problems, geoid determination, advances in spatial/temporal modelling, estimation theory, or the use of high-performance facilities. Demonstrations of mathematical and physical research directly motivated by geodetic practice and ties to other disciplines are welcome. In parallel with theory-oriented results, examinations of novel data-processing methods in various branches of geodetic science and practice are also acceptable. The scope of the session is conceived with a degree of freedom, even though it intends to provide a forum for all theoretical and methodological investigations and results.
