GPS: Actions Needed to Address Ground System Development Problems and User Equipment Production Readiness
GAO-15-657: Published: Sep 9, 2015. Publicly Released: Sep 9, 2015.
The Air Force has experienced significant difficulties developing the Global Positioning System (GPS) next generation operational control system (OCX) and consistently overstated progress to the Office of the Secretary of Defense (OSD) compared to advisory independent assessments it received. It needs $1.1 billion and 4 years more than planned to deliver OCX due to poor acquisition decisions and a...
International Space Station: Measurable Performance Targets and Documentation Needed to Better Assess Management of National Laboratory
GAO-15-397: Published: Apr 27, 2015. Publicly Released: May 27, 2015.
The Center for the Advancement of Science in Space (CASIS), manager of the International Space Station (ISS) National Laboratory, has taken steps to fulfill its management responsibilities contained in its cooperative agreement with the National Aeronautics and Space Administration (NASA), and has initiated the activities required by the NASA Authorization Act of 2010. GAO found that CASIS impleme...
Space Acquisitions: Some Programs Have Overcome Past Problems, but Challenges and Uncertainty Remain for the Future
GAO-15-492T: Published: Apr 29, 2015. Publicly Released: Apr 29, 2015.
In recent and ongoing work, GAO has found that several space system acquisitions have largely overcome acquisition challenges—such as matching resources to requirements, facilitating competition, and parts quality issues—and are producing and launching satellites. But other programs continue to face difficulties, both in technology development and in ensuring ground and user systems are delive...
Space Acquisitions: Space Based Infrared System Could Benefit from Technology Insertion Planning
GAO-15-366: Published: Apr 3, 2015. Publicly Released: Apr 3, 2015.
The Air Force assessed options for replacing older technologies with newer ones—called technology insertion—in the Space Based Infrared System (SBIRS) geosynchronous earth orbit (GEO) satellites 5 and 6. However, the assessment was limited in the number of options it could practically consider because of timing and minimal early investment in technology planning. The Air Force assessed the fea...
Geostationary Weather Satellites: Launch Date Nears, but Remaining Schedule Risks Need to be Addressed
GAO-15-60: Published: Dec 16, 2014. Publicly Released: Jan 15, 2015.
The National Oceanic and Atmospheric Administration (NOAA)'s Geostationary Operational Environmental Satellite-R (GOES-R) program has made major progress in developing its first satellite, including completing testing of satellite instruments. However, the program continues to face challenges in the areas of schedule, cost, and functionality. Specifically, the program has continued to experience d...
Space Acquisitions: DOD Needs More Guidance on Decisions to Store Satellites
GAO-15-97R: Published: Dec 9, 2014. Publicly Released: Dec 9, 2014.
Currently, the Department of Defense’s (DOD) general approach is to launch satellites as soon as they are built. Program offices handle storage on a case-by-case basis based on mission needs and production and launch schedules. Over the last 5 years, DOD generally decided to use storage when satellites on orbit were lasting longer than expected and thereby pushed out the originally planned launc...
DOD Space Systems: Additional Knowledge Would Better Support Decisions about Disaggregating Large Satellites
GAO-15-7: Published: Oct 30, 2014. Publicly Released: Oct 30, 2014.
It is not yet known whether and to what degree disaggregation can help the Department of Defense (DOD) reduce acquisition costs and increase the resilience of its satellite systems. Experts GAO spoke with identified an array of benefits and limitations. For example, acquiring smaller, less complex satellites may require less time and effort to develop and produce. On the other hand, a larger numbe...
U.S. Launch Enterprise: Acquisition Best Practices Can Benefit Future Efforts
GAO-14-776T: Published: Jul 16, 2014. Publicly Released: Jul 16, 2014.
GAO has reported extensively on the Evolved Expendable Launch Vehicle (EELV) program in the past.In 2008, GAO reported that when the Department of Defense (DOD) moved the EELV program from the research and development phase to the sustainment phase in the previous year, DOD eliminated various reporting requirements that would have provided useful oversight to program officials and the Congress.In...
Space Acquisitions: Acquisition Management Continues to Improve but Challenges Persist for Current and Future Programs
GAO-14-382T: Published: Mar 12, 2014. Publicly Released: Mar 12, 2014.
Most of the Department of Defense's (DOD) major satellite acquisition programs are in later stages of acquisition, with the initial satellites having been designed, produced, and launched into orbit while additional satellites of the same design are being produced. A few other major space programs, however, have recently experienced setbacks. For example: the Missile Defense Agency's Precision Tra...
Evolved Expendable Launch Vehicle: Introducing Competition into National Security Space Launch Acquisitions
GAO-14-259T: Published: Mar 5, 2014. Publicly Released: Mar 5, 2014.
The Department of Defense (DOD) began the Evolved Expendable Launch Vehicle (EELV) program in 1995 to provide a new generation of launch vehicles to ensure affordable access to space for government satellites. In November 1997, based on commercial forecasts at that time, the Office of the Secretary of Defense (OSD) approved maintaining competition between two contractors, and in 1998, DOD competit...
