Minisymposium: Spacetime Models of Gravity in Space Geolocation and Acoustics

Abstract

The geometrization of gravity has become one of the cornerstones of modern science having an impact on the industrial progress connected to many activities of daily life. In fact, in the last decades substantial research has been invested into post-Newtonian corrections for high-precision space geodesy and navigation [1–3, 12], as well as into the design of analogue models of gravity by making use of advanced optical and acoustic metamaterials (see e.g. [4, 5, 13]). Other present industrial procedures requiring very accurate timing show the need of innovative development of computationally efficient space-time models for use in space. In particular, these models become important in geolocation of passive radiotransmitters in space and to improve active space debris removal [8, 14, 15]. Moreover, acoustic metamaterials—artificially produced materials with exceptional properties not found in nature—provide the engineer with tools to fabricate acoustic devices with highly unusual features.
