Defense Intelligence Reference Document High-Frequency Gravitational Wave Communications

Defense Intelligence Agency · 57 pages · text from the file's own layer

This Defense Intelligence Reference Document was prepared by the Defense Intelligence Agency under its Advanced Aerospace Weapon System Applications (AAWSA) program, is dated 6 April 2010 and is part of a series of advanced technology reports produced in FY 2009. It reviews proposed laboratory generators and detectors of high-frequency gravitational waves for communications. It favors an infrared-excited molecules transmitter and the Li-Baker detector, estimating about 1.9 million bits per second over 7,000 km through the Earth. It also discusses timing standards and interplanetary navigation uses.

task area, resulting in interface control documentation/drawing review prior to the
critical design reviews of the component equipment areas. Finally, the systems
engineering activity concludes with the development of test plans that will detail
integration activities and reduce integration risk in subsequent phases. These activities
are standard level-of-effort tasks that are rolled into other task bids as a background
activity.
