Development
The basic elements of the system were devised at the National Research Council of Canada in the 1970s, to study car collisions. In 1990, development was transferred to Neptec Design Group, a small commercial enterprise located in Kanata, a suburb of Ottawa. The system runs on Neptec's Advanced Vision Unit (AVU) processing platform, which handles video routing, algorithm processing, video overlays, and the system interface. The operating system is the Unix-like and POSIX compliant QNX Real-time operating system, running the Photon windowing interface. The Photon implementation was optimized to be the most worry free direct manipulation interface possible for the particular needs and work habits of the astronauts.
The Canadian Space Agency was involved at several stages in the development and deployment of the space vision system. Training for the system takes place in the simulators located at the agency's headquarters at the John H. Chapman Space Centre near Montreal.
