Space Network

An additional TDRS, F1, provides dedicated support to the National Science Foundation (NSF) through the use of the WSC Alternate Relay Terminal (WART).

The Network Control Center Data System (NCCDS) is an element of the SN ground segment.

[3] Collocated with the White Sands Tracking and Data Relay Satellite System, the NCCDS is the operations control facility for the network.

A customer may obtain Space Network support by submitting specific schedule requests to or establishing generic requirements with the NCCDS.

The Goddard Space Flight Center uses the NAMs as a means of letting customers know of any performance constraints associated with the TDRS spacecraft.
