The provision of coverage to terrestrial wireless subscribers through an arrangement or agreement (see §
1. 9047 of this chapter) between one or more NGSO or GSO operator(s) and one or more terrestrial wireless licensee(s), involving transmissions between space stations and SCS earth stations. NGSO and GSO operators and terrestrial wireless service licensees seeking to provide SCS must be authorized… (Read More →)

Specific type of application that provides security services or security management capabilities at application level rather than embedded in the communication architecture [ECMATR46].

A single-sideband emission in which the carrier is virtually suppressed and not intended to be used for demodulation. [NTIA] [RR]

Amplitude modulation (AM) transmission in which the carrier level is reduced below that required for demodulation.
Note 1: Reduction of the carrier level permits higher power levels in the sidebands than would be possible with conventional AM transmission.
Note 2: Carrier power must be restored by the receiving station to permit demodulation.
Note 3: Suppressed carrier transmission is a special… (Read More →)

[An] Action, procedure, modification, or device that reduces the level of, or inhibits the generation of, compromising emanations in an information system (IS). [INFOSEC-99]

Slang. To search the Web, by navigating in a nonlinear and seemingly random way, often without a specific objective.

The refractive index of the Earth's atmosphere, calculated from observations of pressure, temperature, and humidity at the surface of the Earth.
Note: The surface refractivity gradient is the difference in refractive index between the surface and a given altitude, such as between the surface and 1000 m.

A wave that is guided along the interface between two different media or by a refractive index gradient.
Note 1: The field components of the wave diminish with distance from the interface.
Note 2: Optical energy is not converted from the surface wave field to another form of energy and the wave does not have a component directed normal to… (Read More →)
