GLADE: Gravitational Light-Bending Astrometry Dual-Satellite Experiment

open access: yesApplied Sciences
Light bending is one of the classical tests of general relativity and is a crucial aspect to be taken into account for accurate assessments of photon propagation. In particular, high-precision astrometry can constrain theoretical models of gravitation in
