Peter Garland has worked on Satellite Communications in Canada for well over 35 Years. During that time he has been involved in nearly every program where the state of art was moved forward. In the mid-nineties he led studies that eventually resulted in the flight of an advanced Ka Band digital processing payload on the Anik F2 satellite. He also led the team that first developed and promoted the DVB-RCS standard for two way satellite communications. Peter was recently presented with the 2014 American Institute of Aeronautics and Astronautics (AIAA) award for achievement in Aerospace Communications, only the second Canadian and the second UK born recipient to be presented with this international award. He is also currently Chairman of the Communications Systems Technical Committee of the AIAA.
