GPS III

Abstract

GPS III is the next generation Space Vehicle (SV) supporting the GPS constellation. GPS III SVs will deliver significant enhancements, including a new civil (L1C) Galileo-compatible signal, enhanced anti-jam power, and a growth path to full warfighter capabilities. GPS III Satellite Vehicles (SVs) 03 - 08 are in the Production & Deployment Phase. Funds in this project are for GPS III SVs 01 - 08 design and development and will support research, development, test and evaluation of GPS III SVs 01-02 and risk reducing simulators through a structured systems engineering approach that matures and delivers two SVs for launch. The program includes capability maturation and risk reduction efforts (Space Modernization Initiatives (SMI)) to affordably develop follow-on performance parameters. For example, as part of reducing the cost to orbit, SMI includes dual launch initiatives to support 2 (two) SVs launching on 1 (one) launch vehicle. These initiatives develop and refine satellite integration/launch/on-orbit operations concepts, requirements, interfaces, integrated schedule, and design trades. A GPS III SV-09+ delta Preliminary Design Review (dPDR) will produce radiation hardness assessments, a preliminary dual launch annex to the GPS III - Atlas V ICD, a dual-band, dual-launch TT&C design, and preliminary updates to the ground segment ICDs. Additionally, the program includes engineering studies and analyses, trade studies, system development, test and evaluation efforts, integrated logistics support products, on-orbit support, and mission operations supporting civil applications that protect U.S. military and allies' use of GPS. Funds in this Project for GPS III SVs 09 and beyond include engineering and development, affordable on-ramps for full GPS III warfighter capabilities (e.g., better signal maintainability, digital waveform generator (DWG), increased regional power, Unified S-Band (USB), near real-time command and control, and the civil search and rescue payload (SAR/GPS)).
