GLOBAL POSITIONING SYSTEM (GPS) III

SYSTEM DEFINITION AND RISK REDUCTION (SD/RR)

STATEMENT OF OBJECTIVES (SOO)

30 August 2001

# Program Overview

The GPS III program objective is to preserve and build on the successes
of the Navstar Global Positioning System (GPS) by creating a new
architecture (based on the operational requirements of the AFSPC/ACC
003-92-I/II/III GPS ORD, dated 18 Feb 2000) for the assured delivery of
enhanced position, velocity, and timing (PVT) signals, and related
services to meet the needs of the next generation of GPS users. The GPS
III program includes an integrated space segment (SS) and control
segment (CS) system that incorporates the Nuclear Detonation Detection
System (NUDET) and defines the Signal-in-Space (SIS) to User Equipment
(UE) interface. The system should provide a best value solution with the
flexibility to anticipate and respond to future military and civilian
needs. The GPS III security infrastructure should provide user access to
and protection of the entire system. The GPS III system should
facilitate the incorporation of additional mission capabilities (i.e.
Blue Force Tracking (BFT), Search and Rescue (SAR) missions, etc.).

# System Definition and Risk Reduction (SD/RR) Contract Objectives

SD/RR is the second effort in a multi-phased acquisition approach for
GPS III that began with the System Architecture and Requirements
Development (SA/RD) effort. This effort, also called Concept
Exploration, evaluated military and civil utility as well as reduced the
system performance trade space for the subsequent SD/RR effort. The
technical requirements trade space derived from the SA/RD effort has
been synthesized into a Draft System Specification (DSS). The DSS is
intended to provide the technical performance thresholds and objectives
for the SD/RR effort. Based on this DSS and the associated life cycle
cost (LCC) estimates for its implementation, the Government estimates
the bound for the LCC of GPS III to range from [TBD]{.underline} to
[TBD]{.underline}. This Government cost bound is issued for guidance
only. The GPS III development and acquisition includes the SD/RR effort
as well as system development, demonstration, production, transition,
deployment, operations, support, sustainment, and disposal of GPS III.
Thus, the LCC estimate range covers the cost of the space, launch, and
control segments, as well as development and management of the SIS
interfaces to the UE and associated interface-working groups (ICWGs).

By conducting the SD/RR effort, the Government expects to understand
both the risks and the costs/benefits inherent in the way the system,
segment, and subsystem level requirements are allocated. Additionally,
the Government expects to understand the risk and timeline associated
with transitioning legacy GPS elements to GPS III. The contractor must
demonstrate how they plan to provide the best value GPS III at an
acceptable risk using Cost As an Independent Variable (CAIV) trades to
optimize the system's performance and utility to users consistent with
prudent LCC. The contractor must also demonstrate sound systems
engineering, risk management, test and evaluation, program management,
and system security engineering capabilities. The Government plans to
use selected SD/RR products to help make the down select decision to a
single GPS III Prime/System Integration (PSI) contractor for System
Design and Demonstration (SDD) and all subsequent phases. By the end of
the SD/RR effort, the Government expects to have a set of segment level
specifications and an architecture description for development and
demonstration.

The specific objectives for the SD/RR contract are divided into System
Definition, Risk Management and Reduction, Program Management, and
Prime/Systems Integrator (PSI) Study as described in the following
sections.

# System Definition

# Risk Management and Reduction 

Provide the following support to define GPS III risk management and
reduction during the SD/RR effort to achieve a flexible and acceptable
GPS III process and appropriate levels of risk to enter the next phase.

##  4.1 The contractor will develop a risk management process that includes risk discovery, identification, isolation, mapping, prioritization, sources and drivers, root cause analyses (where applicable), tracking, reporting, and specific, prioritized mitigation activities. The risk management and reduction activities apply to all future phases of GPS III including, but not limited to, development, manufacturing, test and evaluation, production, transition, on-site space vehicle storage, launch, deployment, and operations and support.  {#the-contractor-will-develop-a-risk-management-process-that-includes-risk-discovery-identification-isolation-mapping-prioritization-sources-and-drivers-root-cause-analyses-where-applicable-tracking-reporting-and-specific-prioritized-mitigation-activities.-the-risk-management-and-reduction-activities-apply-to-all-future-phases-of-gps-iii-including-but-not-limited-to-development-manufacturing-test-and-evaluation-production-transition-on-site-space-vehicle-storage-launch-deployment-and-operations-and-support. .Style2 .unnumbered}

##  4.2 Based on the assessed risk and proposed mitigation activities, the contractor will conduct studies, demonstrations, breadboard testing, and/or software prototyping to achieve an acceptable level of risk by Preliminary Design Review (PDR). {#based-on-the-assessed-risk-and-proposed-mitigation-activities-the-contractor-will-conduct-studies-demonstrations-breadboard-testing-andor-software-prototyping-to-achieve-an-acceptable-level-of-risk-by-preliminary-design-review-pdr. .Style2 .unnumbered}

# Prime/System Integrator (PSI) Study

The contractor will conduct a PSI study in close collaboration with the
Government during the SD/RR effort. This study will review the full
range of potential roles and responsibilities of the GPS III PSI
contractor. The contractor will develop a timeline and a transition plan
to migrate responsibilities into the GPS III contract. The full range of
non-inherently Government roles, responsibilities, and functions will be
evaluated in cooperation with the JPO to determine which should migrate
to the GPS III contractor.

# 6.0 Program Management 

The contractor should address the necessary SD/RR program management
activities within a comprehensive plan for the conduct of this and all
subsequent phases of GPS III. The fundamental management plan will cover
the system definition, risk management and reduction, and PSI tasks
performed over the next two years. Nevertheless, the contractor should
develop a comprehensive management concept that allows for a smooth
transition from SD/RR to SDD and beyond.
