Secure Telecommand Channel Secure Telecommand Channel is a protected command path that ensures telecommand messages are authenticated, controlled, and resistant to unauthorized access. Protocol Signal Masking Signal Masking is the use of spectral, timing, or power behavior that makes a signal harder to detect, identify, or isolate. It lowers signal observability. Operations Space Segment Space Segment is the portion of a satellite system located in space, including spacecraft, payloads, and orbiting assets that provide the service. Hardware Star Tracker Star Tracker is an optical attitude sensor that determines spacecraft orientation by identifying stars in its field of view and comparing observed star positions with an internal catalog to compute… Hardware Sun Sensor Sun Sensor is an attitude sensor that determines spacecraft orientation by detecting the direction of the Sun and translating that measurement into an angular reference for the spacecraft. Hardware Surveillance Relay Surveillance Relay is a relay link or node that forwards surveillance data or extends surveillance communications coverage. Software Tactical Terminal Tactical Terminal is a communications terminal designed for use in operational or field-deployed tactical environments. It supports tactical communications and connectivity through portable, resilient endpoints. Hardware Traffic Concealment Traffic Concealment is the practice of hiding traffic patterns, volume, or content characteristics to reduce detectability or inference. Concept/Framework UAV Relay UAV Relay is a communications relay provided by an unmanned aerial vehicle to extend coverage or bridge blocked links. Hardware Vehicular Terminal Vehicular Terminal is a communications terminal mounted on or used within a vehicle to provide in-motion connectivity, enabling network access during movement or operation away from fixed infrastructure.
