172:, the NCCDS is the operations control facility for the network. It schedules most Space Network elements and supporting elements and provides interfaces for planning, acquisition, control, and status of the Space Network. The NCCDS is the point-of-contact between customers (who have satellites in orbit) and the Space Network for most scheduling and real-time performance. A customer may obtain Space Network support by submitting specific schedule requests to or establishing generic requirements with the NCCDS. The NCCDS translates customers’ requirements into specific
