GPS III
Abstract
GPS III is the next generation Space Vehicle (SV) supporting the GPS constellation and is funded in PE 35265F. 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 SV03-10 is in the Production & Deployment Phase. RDT&E, AF PE 0305265F funds GPS III and supports research, development, test and evaluation of GPS III SV01-02 and risk-reducing simulators through a systems engineering approach that matures and delivers SVs for launch. This PE includes SV01-02 engineering studies and analyses, trade studies, system development, test and evaluation efforts, integrated logistics support products, on-orbit support, and mission operations support for civil and military applications that protect U.S. military and allied use of GPS. The program also includes contingency operations as risk mitigation to late Next Generation Operational Control System (OCX) delivery which will allow for command and control of GPS III SVs. Space Modernization Initiative (SMI) focuses on space vehicle affordability and capability, addresses future requirements and resiliency needs, and expands the industrial base to enhance future competition. Phase 1 will address GPS Enterprise Analysis of Alternative (AoA) recommendations to increase GPS signal strength from space by maturing navigation payload technologies that include a new regional M-Code capability. The Air Force is using its research laboratories to mature an On-Orbit Reprogrammable Digital Waveform Generator (ORDWG) which will provide signal flexibility (to change the signal form while the satellite is on-orbit). This effort will be funded with Air Force Research Lab’s Science & Technology (S&T) funding and PE 0305265F to increase the number of alternate navigation payload awards.
