Abstract
By analysing slant path propagation events observed using the 20 GHz switched polarisation beacon of the Olympus satellite, it is shown that the phase offset on transmission between the two polarisations was approximately 49°, with the near-vertical polarisation lagging. Knowledge of this offset makes it possible to determine the medium transmission matrix with all terms properly calibrated in their relative phase
