RAND researchers evaluated two commercial space markets to understand opportunities, challenges, and risks that the Department of the Air Force could encounter when making decisions to invest in commercial space capabilities.
The Global Positioning System (GPS) has a key role in national positioning, navigation, and timing (PNT), but it is far from the only source of capability for PNT. Would national investment in GPS backup capabilities be warranted, given the potential threats to its functioning?
Seventy years ago, a group of researchers established the independent RAND Corporation. From the first satellite design, to helping ensure GPS as a public good, to laying the groundwork for the internet, RAND has been making a difference ever since.
According to consumer research, the ability to consume media, write an email, or even sleep during transport is a key selling point for self-driving cars, which could be available in the near future. Autonomous vehicle technology could also produce a wide range of public benefits.
A geospatial software tool-evaluation study assessed 14 recent tool developments funded by the National Institute of Justice. The study integrates input from tool developers and tool users with RAND's independent tool assessments.
Recent advances in GPS data processing have demonstrated that ground-based GPS receivers are capable of detecting ionospheric TEC perturbations caused by surface-generated Rayleigh, acoustic and gravity waves.
Why have the costs of acquiring space systems been so high? What are the sources of the problems? To answer these questions, RAND researchers examined the sources of cost growth of Air Force space systems and undertook an extensive study of two space systems.
The Global Positioning System (GPS) is a space-based signal providing precise timing, location, and velocity information. Just as any number of receivers can tune into a commercial TV or radio station, there is no limit on the number of people who can use GPS.
The proliferation of Third World ballistic missiles is a major concern for the U.S. government. This paper evaluates the effectiveness of U.S. control policies as they pertain to ballistic missiles, focusing on those with ranges of 300-1000 km.
Since the Global Positioning System (GPS) was originally deployed to aid U.S. armed forces in navigation and position location, it has evolved into a resource supporting civil, scientific, and commercial functions—from air traffic control to the Internet—with precision location and timing information.
The evolution of GPS into an information system with a substantial international user community has raised complex policy questions for U.S. decisionmakers on a variety of issues affecting national defense, commerce, and foreign policy.
