Frequency Hopping Frequency Hopping is the periodic change of carrier frequency according to a predefined or adaptive sequence. Protocol Hardened Terminal Hardened Terminal is a communications terminal designed to resist environmental stress, damage, interference, or operational disruption while maintaining functional communications capability in demanding field conditions. Hardware Information Assurance Information Assurance is the practice of preserving confidentiality, integrity, availability, and trust in information and information systems. It protects information system behavior and data. Concept/Framework Information Assurance For Satcom Information Assurance For Satcom is the set of security, integrity, availability, and governance controls applied to satellite communications systems and traffic. Concept/Framework Inter Satellite Link An Inter Satellite Link is a communication path used for data exchange between satellites, enabling spacecraft to relay information directly in orbit. Hardware Key Management For Satcom Key Management For Satcom is the process of generating, distributing, storing, rotating, and revoking cryptographic keys used in satellite communications. Software LEO LEO is low Earth orbit, an orbital regime relatively close to Earth used by satellites in communications and observation systems. Concept/Framework LEO Satellite A LEO Satellite is a spacecraft operating in low Earth orbit used for communications, observation, navigation, or other orbital services. Hardware Link Assurance Link Assurance is the effort to verify, monitor, and maintain the quality and availability of a communications link. It keeps the link fit for service. Operations Magnetorquer Magnetorquer is an attitude control device that uses interaction with a magnetic field to apply torque to a spacecraft, supporting orientation control through magnetic forces without conventional propellant.
