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?
The early space domain was dominated by two superpowers. Today, the world has more than 60 spacefaring nations, multiple commercial space operators, and a global economy that is inextricably linked to space. Now is the time to develop responsible space norms.
The ability to provide relatively low cost internet access outside of government control is both a challenge for authoritarian states and an opportunity for democracies. What are low-altitude, low-latency satellites and why are authoritarian states so concerned?
Some 70 countries and multinational organizations own or operate satellites and there are plans for many more. Multilateral cooperative efforts could help set a foundation for the adoption of transparency and confidence measures that offer realistic hope of reducing risks and protecting freedom of access to space for all nations.
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.
Space-enabled connectivity, technology, and services support a diverse array of political, military, and economic activities, many of which modern life on Earth relies upon and which the public often takes for granted. How prepared is global society to deal with the growing reliance on this technology and to mitigate associated risks?
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.
This manual explains how to use the Defensive Space Analysis Tool (DSPAT), which was developed to compare alternative approaches to space control in terms of their mission effectiveness, feasibility, escalation risk, and political cost.
Signals intelligence (SIGINT) is intelligence gathered from communications, electronics, or foreign instrumentation. This has traditionally been considered a governmental function. But new technologies are changing that. Now private citizens can conduct SIGINT activities.
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.
Satellite anomalies are malfunctions caused by solar particles, cosmic rays, or even space debris. A shared database could help identify solutions to prolong the lifetime of spacecraft that experience problems, and could be implemented in a way that would protect the privacy of the satellite operators.
