Pat Norris has worked in the space and software industries since the 1960s. Born and
educated in Ireland, he has been involved in the space and software sectors on both sides of the Atlantic in both public and private sectors for more than 40 years. 

Pat started his working life in the UK at the radar laboratories of Elliott Automation.  He moved to the USA in 1966 working for the RCA Service Company at the Goddard Space Flight Center, supporting NASA's activities in orbit determination, gravity field modeling and satellite geodesy. In 1967 he joined TRW to work on the Apollo moon landing program in Houston Texas. He led a small team of engineers analyzing the challenges of navigating to the moon and back. He received the Apollo individual Achievement Award from Neil Armstrong in August 1969 for his endeavors - in particular the determination of accurate geodetic locations for the one third of NASA tracking stations whose data had to be binned in the Apollo 8 mission.

From 1971 to 1980 he worked for the European Space Agency as system and software
engineer on the Hubble Space Telescope, the Meteosat weather satellite, the Aerosat
navigation satellite and the OTS telecom satellite.

Since 1980, Pat has worked for CGI (formerly called Logica) in the UK. This multinational software company is now the European leader in space software - its software currently supports the missions of more than 200 satellites.  Space missions in which Pat has been involved in this role include the Giotto probe to Halley's comet, the Hipparcos star mapper, the Huygens probe to Titan, the Galileo navigation system, the Inmarsat-4 global mobile broadband network, the XMM-Newton X-ray astronomy observatory and the Skynet 5 military communications satellite.  His current role is Adviser to the Vice President of the Space Business Unit.

Pat was Chairman of the Royal Aeronautical Society Space Group from 2004 to 2012, and is a former Chairman of the trade association of Britain's space industry, UKspace (previously called UKISC).  He is a Fellow of the Royal Institute of Navigation, a Fellow of the Royal Aeronautical Society and a Chartered Engineer (CITP).

In addition to his books, Pat has written many magazine articles and contributed chapters or sections to two multi-author books: 


  • a section on the applications of space in the International Handbook of Space Technology 
  • two chapters in the Handbook of Space Security: (1) Eavesdropping Satellites, and (2) USA Military Satellites
