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 SV03-08 is in the Production & Deployment Phase. Funds in this project are for GPS III SV01-08 design and development and will support research, development, test and evaluation of GPS III SV01-02, and risk-reducing simulators through a structured systems engineering approach that matures and delivers space vehicles for launch. Space Modernization Initiatives (SMI) focuses on space vehicle affordability and capability, addresses future requirements and resilience needs, and expands the industrial base to enhance future competition. For example, this includes the initial systems design work for incorporating space vehicle technology improvements on items such as second source atomic clocks, smart solar cells that provides 30% more efficiency, alternate transmitter assembly that provides increased power efficiency at a reduced recurring cost, lithium ion batteries which address battery obsolescence issues and also offer a substantial weight savings, and a dual space-ground link system (SGLS)/Unified S-Band (USB) communication channel to be compliant with the USB interface. Additionally, the program includes enterprise 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.
