Space Communications Architecture and Standards

The goal of Architecture and Standards is to identify future SCaN needs and technologies according to standard engineering, architecting and simulation/emulation processes and provide a program wide standard analysis environment. The following projects are included in the Space Communications Architecture and Data Standards area.


Designing any new space communications architecture designs currently involves separately modeling each of the SCaN three networks, which are the Near Earth Network (NEN), the Space Network (SN), and the Deep Space Network (DSN). Each of these models must then be fully integrated prior to quantifying network performance via metrics such as feasibility assessments, capacity … Read the rest ⇢


The mission of the Space Network Ground Segment Sustainment (SGSS) Project is to implement a flexible and extensible ground segment that will allow the Space Network (SN) to maintain high levels of service in the future, accommodate new users and capabilities, while reducing the effort required to operate and maintain the system.

Data Standards

NASA GRC provides support to the development of interoperability standards for space by participating in Consultative Committee for Space Data Systems (CCSDS) Working Groups. Founded in 1982 by the major space agencies of the world,the CCSDS is a multi-national forumfor the development of communications and data systems standards for spaceflight. Today, leading space communications experts … Read the rest ⇢

Program Systems Engineering

The MSC Program Systems Engineering (PSE) team at NASA GRC supports the systems engineering activities of the Space Communication and Navigations (SCaN) Program at NASA Headquarters. It works with other teams at Headquarters, NASA Goddard Space Flight Center, and at the Jet Propulsion Lab to provide the systems engineering function for SCaN.
