Remote Operations

Round Trip Time Round Trip Time is the total time required for a signal or packet to travel from a source to a destination and back. It measures end-to-end bidirectional delay. Protocol Satellite Communications Satellite communications is a communications architecture in which user traffic is relayed via satellites between remote endpoints and terrestrial network infrastructure. The system includes the user terminal, the space segment,… Concept/Framework Satellite Operations Satellite operations is the set of activities used to command, monitor, sustain, and recover satellites during mission life. It includes scheduling, anomaly handling, station keeping, telemetry analysis, and coordination with… Operations SCADA SCADA is a supervisory control and data acquisition system used to monitor and control distributed industrial processes. It collects telemetry from field devices and supports operator actions. Operations Secure Telecommand Channel Secure Telecommand Channel is a protected command path that ensures telecommand messages are authenticated, controlled, and resistant to unauthorized access. Protocol Secure Tunneling Secure Tunneling is the use of an encrypted or protected tunnel to carry traffic between endpoints across an untrusted network. It preserves confidentiality or integrity in transit. Protocol Sensor A sensor is a transducer that detects a property of the environment or process and produces a corresponding electrical, digital, or optical signal. That signal is then used for monitoring,… Hardware Sensor Network A Sensor Network is a set of distributed sensors that collect and transmit data about physical conditions or events. It supports monitoring and automation through distributed sensing. Concept/Framework Service Handoff Service handoff is the operational process of moving an ongoing connection, session, or service flow from one network element or path to another while preserving continuity as much as possible.… Concept/Framework 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
