Shawyer is an aerospace engineer and a director of United Kingdom (UK)-based Satellite Propulsion Research Ltd (SPR), a company that he founded to develop EmDrive technology.〔 ==Career== Shawyer conducted aerospace research and development work in the defence sector in his early career, eventually transitioning into various positions at EADS Astrium (formerly Matra Marconi Space). He worked on the European Galileo (satellite navigation) project, in a consulting role.〔 In 2001, he founded Satellite Propulsion Research Ltd, financed with private investments, grants, and commercial contacts.〔 His work on an electromagnetic propulsion drive has generated both public interest and scientific skepticism. In 2015, Martin Tajmar presented his findings relating to Shawyer's claims to the American Institute for Aeronautics and Astronautics' Propulsion and Energy Forum and Exposition. The abstract of his report concluded: " Our test campaign can not confirm or refute the claims of the EMDrive but intends to independently assess possible side-effects in the measurements methods used so far. Nevertheless, we do observe thrusts close to the actual predictions after eliminating many possible error sources that should warrant further investigation into the phenomena." 〔Tajmar, M. and Fiedler, G.
