Space Communications and Navigation Program

It was previously known as the Space Communications & Data Systems (SCDS) Program.

Before NASA's administrator Michael D. Griffin created SCaN to direct an integrated networks program, different organizations at NASA Headquarters have managed the Agency's space communications capabilities and functions under separate Programs using a variety of administrative approaches.

SCaN is viewed as a service provider supporting interfaces and performing a standard set of functions, including:[4] Communications with spaceborne platforms is performed by RF, with a selection of spectra, modulation, and encoding methods, enumerated below.

The Deep Space Network communicates with spacecraft using S-band, X-band, and Ka-band.

[6] The Space Network (used for near-Earth communications) supports the following encoding schemes:[7] The Reed–Solomon method is used as the initial error-correcting block code prior to the selected secondary encoding scheme.
