NASA Awards Space Network Expansion-East Option

WASHINGTON -- NASA awarded the option for the Space Network Expansion-East, under the Space Network Ground Segment Sustainment contract, to General Dynamics C4 Systems of Scottsdale, Ariz.

The cost-plus-award fee, indefinite-delivery, indefinite-quantity option has a total estimated value of $32.7 million. The period of performance is from March 1, 2011, through Sept. 2, 2015. The base contract was awarded on June 15, 2010.

The Space Network Ground Segment is part of NASA's Space Network. The
agency's Tracking and Data Relay Satellites (TDRS) comprise the space
segment. The network provides the resources for global
space-to-ground telecommunications and tracking coverage for low and
near-Earth orbit robotic and human spaceflight missions.

Under the option, General Dynamics will implement the ground segment
at NASA's new ground terminal in Blossom Point, Md., to enable the
Space Network to continue to deliver high quality services and meet
stakeholder requirements.

The Space Network Ground Segment Sustainment effort includes replacing
aging systems at existing Space Network ground segments; creating a
more flexible and expandable architecture; facilitating the
integration of NASA's Space Communications and Navigation networks;
addressing customer requirements and advances in technology; and
implementing new methods and capabilities for using the TDRS to
support Space Network user spacecraft.

The effort also includes expanding and improving the methods for Space
Network user control centers to interface with the Space Network
Ground Segment for data and service planning and control; and
maintaining long-term operational performance, reliability and
