DOI: 10.1007/s00190-020-01441-0
Abstract: Currently, Global Navigation Satellite Systems (GNSS) do not contribute to the realization of origin and scale of combined global terrestrial reference frame (TRF) solutions due to present system design limitations. The future Galileo-like medium Earth… read more here.

DOI: 10.1007/s00407-019-00236-w
Abstract: Johannes Kepler dedicated much of his work to discover a law for the refraction of light. Unfortunately, he formulated an incorrect law. Nevertheless, it was useful for anticipating the behavior of light in some specific… read more here.

DOI: 10.1016/j.heliyon.2019.e01274
Abstract: The original form of Kepler's Third Law contains a caveat regarding the requirement of small eccentricities – a fact that has not been incorporated by the traditional Newtonian derivations. This constraint is analyzed, and a… read more here.
