Relay Ground Station - South (RGS-S) Antenna

Background
The Relay Ground Station South (RGS-S) project is sponsored by the United States Space Force (USSF) and aims to provide essential support for the Space Systems Command (SSC) mission. Located at Schriever Space Force Base outside of Colorado Springs, CO, the project will facilitate the operation of Overhead Persistent Infrared (OPIR) satellite ground stations.

The project is funded under Research, Development, Test, and Evaluation (RDT&E) appropriations and includes design, procurement, development, integration, and testing of advanced technology hardware and software systems for communication with various space vehicles. The contract will be executed using a Design-Build method, requiring the contractor to deliver a complete design and construction of usable facilities.

Work Details
The contractor will be responsible for designing, procuring, installing, and commissioning facilities and infrastructure primarily consisting of:
- Concrete pads
- Antenna pedestal foundations
- Radome ringwalls
- Site utilities
- Backup generators
- Fuel tanks
- Pathways and cabling
- Shelters.

The structural scope includes building/equipment pads, antenna pedestal foundations, radome ringwall foundations, radome ECU pads, and transformer pads. The project must meet specific design criteria including risk category IV standards as per UFC guidelines. Major components include Ground Terminal Equipment (GTE), Communications and Networking Equipment (CNE), Facilities and Infrastructure (F&I), and Command Control Communications Computers Intelligence/Information Technology (C4I/IT). The GTE will consist of 13.5-meter antennas housed in environmentally controlled radomes capable of receiving communications from space vehicles in various frequency bands.

Period of Performance
The project is expected to be constructed and commissioned no later than September 2027.

Place of Performance
Schriever Space Force Base outside of Colorado Springs, CO.
