Satellites Could Detect Nuclear Tests by Identifying Ionospheric Disturbance
Scientists are examining the possibility of using global satellite networks to help detect clandestine underground nuclear explosions (UNE). The International Monitoring System (IMS), established by the Comprehensive Nuclear-Test-Ban Treaty (CTBT), currently employs seismic networks, hydroacoustic networks and radionuclide networks to detect clandestine nuclear weapons testing; … [Read more...]
FCC Approves Commercial Use of U.S. Military Radar Spectrum
The Federal Communications Commission has approved a proposal to share U.S. military wireless spectrum with commercial users. The 3.5GHz band is currently used by high-power military radar services and is not traditionally seen as ideal for mobile broadband because radar can limit the widespread use of spectrum. According to the FCC proposal, the proposed commercial broadband … [Read more...]
