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?
As space becomes more congested with satellites, the need for every nation to actively participate in the space safety coordination system grows. Most spacefaring countries participate, but a few countries do not—notably, Russia and China. That creates greater potential for collisions and hazards from debris.
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.
Merton Davies spent his early years using satellite imagery to spy on terrestrial targets. His work led to the first successful reconnaissance satellite, Corona. Later, he used deep-space photographs to map the planets in our solar system.
China is trying to change the status quo in the Indo-Pacific through gray zone coercion -- actions below the threshold that would trigger a military response. This report focuses on deterring such coercion in the maritime, cyber, and space domains.
This report explores the missions and organization of China's Strategic Support Force, created in 2015 to develop and employ space capabilities, in particular launch and operation of satellites to provide C4ISR capabilities for joint operations.
An assessment of historical cases of Air Force innovation — or apparent failure to innovate — sheds light on whether the service is sufficiently innovative today and what can be done to make it more innovative for the future.
As Department of Defense plans for the next-generation space systems in an increasingly challenging fiscal and security environment, it is important to apply lessons learned from past space acquisition, which had experienced many difficulties.
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.
Reports earlier this year that the U.S. Department of Defense leased a Chinese satellite to support military operations in Africa sparked concern that the arrangement could compromise control over U.S. military communications, or, worse, allow Chinese intelligence gatherers access to privileged military data.
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.
Space assets are vital to the economic, social, and military interests of the United States. Sustainment complexities suggest a need to define a AFSPC commandwide sustainment philosophy separating demand, supply, and integrator processes.
As space systems age, the U.S. Air Force Space Command needs to understand how budgeting for the maintenance and sustainment of ground segments affects the performance of their associated space systems. New metrics and models can help this process.
This monograph presents findings of a RAND Project AIR FORCE research project documenting lessons learned from the implementation of evolutionary acquisition (EA) strategies on major Defense Department military space programs.
Merton Edward Davies (1917-2001) was a major contributor to U.S. space efforts from when he first became affiliated with the RAND Corporation in 1947 until his death in 2001, at which time he still maintained his office at RAND.
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.
