1 Scope

1.1 Purpose

The purpose of this document is to specify facilities and infrastructure (F&I) needed to support mission requirements for Relay Ground Station – South (RGS-S), based on established stakeholder requirements and assumptions. This document is intended for use by the Design- Construction Agent (DCA) (i.e., United States Army Corps of Engineers [USACE]) to facilitate development of planning products (e.g., Request For Proposals [RFPs]).

1.2 Document Revision Plan

To meet the planned site activation date, Naval Information Warfare Center (NIWC) Pacific plans to issue versions of the Site Preliminary Design Document (SPDD) to support the site preparation Request For Proposals (RFP) process, as illustrated and described below.

Figure 1 – Site Documents Flow Chart

SPDD Version 1.0 will incorporate validated derived F&I requirements and specifications, based on the approved requirement documents and SSC-provided antenna placement obscuration analysis. Preliminary F&I requirements and specifications will also be included, based on specifications from previous RGS system design(s) and stated assumptions.

SPDD Version 2.0 will incorporate any updated specifications and requirements provided by the Ground Terminal Equipment (GTE) / Communications and Networking Equipment (CNE) contractor. These updated specifications and requirements will be provided by the GTE/CNE contractor to incorporate any additional F&I needed to support GTE and CNE. Preliminary site design developed as part of the planning process (e.g., draft RFP) will also be incorporated into the updated SPDD.

This document does not supersede government requirements and standards that drive the design of the facility by the design agent. The requirements represented herein are necessary to support the project; however, if any of the requirements specified in this document violate any facility requirements (e.g., life safety, electrical and energy standards, etc.), it is the responsibility of the design agent to address the potential issue and work with NIWC Pacific representatives to develop alternatives that will meet the core goals of the project.

1.3 Project Background

RGS-S is sponsored by the United States Space Force (USSF) and is a vital part of the Overhead Persistent Infrared (OPIR) enterprise modernization effort. RGS-S will support the Next-Generation Overhead Persistent Infrared (Next-GEN OPIR) programs and continued operations of legacy Space Based Infrared System (SBIRS) capabilities.

RGS-S is a Research, Development, Test, and Evaluation (RDT&E) appropriations funded project, which includes design, procurement, development, integration, and testing of advanced technology hardware and software systems capable of uplink and downlink communications with Legacy SBIRS GEO, DSP, Next Generation GEO (NGG), and Next Generation Polar (NGP) space vehicles. This RDT&E funded project will be a lights-out facility, located at Schriever Space Force Base in Colorado. Site improvements will be necessary to support system equipment.

1.3.1 Work Breakdown and Contracts

The facility will be comprised of four work areas that will be accomplished with three separate contracts. The work areas are:

1. Ground Terminal Equipment, accomplished by GTE/CNE contractor
