SCaN Integrated Network
› Larger Image
The Deep Space Network (DSN), the Near Earth Network (NEN) and the Space Network (SN) are the three networks that Space Communications and Navigation (SCaN) uses to support missions in space. Each of these networks provides both NASA and non-NASA missions tracking, telemetry and command (TT&C), and audio and visual capabilities in order for missions to complete their objectives and goals in space.
Currently, each of these networks operates distinctly and separately from the other. Project managers from missions need to “shop around” for which network will be able to best meet their needs, which one would be able to accommodate them closest to the time they want to launch and the bandwidth the satellite has to communicate on. This process can sometimes be tedious and costly.
SCaN has recognized the issues and has recently conducted studies on how to solve the problems. SCaN has concluded that the three networks will be moving towards an integrated network by 2018. The SCaN Integrated Network (SCaNIN) will provide standard services, components and interfaces to all missions. This “one stop shopping” will reduce cost and duplication to the missions and to NASA.
