Detecting Ionospheric TEC Perturbations Caused by Natural Hazards Using a Global Network of GPS Receivers: The Tohoku Case Study — 2012
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.
Current challenges for space policy are examined in this study, particularly those derived from the growth of space commerce and resulting conflicts between public and private sector interests.
Small spacecraft have become popular for a number of reasons, most prominently the needs to reduce overall cost, be built more quickly, and spread mission risks. Despite the risks, however, small spacecraft fulfill important roles in earth science, astrophysics, space physics, and planetary science. NASA's current generation of small spacecraft is capable of impressive levels of performance.
As of the end of 1997, the U.S. had cooperative agreements with 76 countries and six multinational organizations covering the operations of 32 active satellites. This report catalogs the agreements and assesses the extent of interagency coordination.
Global Positioning System: Market Projections and Trends in the Newest Global Information Utility — 1997
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.
Roles and impacts of RAND in the pre-Apollo space program of the United States
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.
Statement before the Subcommittee on Space and Aeronautics, U.S. House of Representatives, July 24, 1996.
This study identifies major opportunities and vulnerabilities created by Global Positioning System (GPS) for U.S. defense, commercial, and foreign policy interests, and makes recommendations for U.S. policy toward GPS.
A Policy Direction for the Global Positioning System: Balancing National Security and Commercial Interests — 1994
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.
