Mechanically-Steered Antenna A mechanically-steered antenna is a directional antenna system that uses motors or other mechanical actuators to alter pointing direction and maintain alignment with a target. It is used when physical… Hardware MEO MEO is medium Earth orbit, an orbital regime between low Earth orbit and geostationary orbit used by some satellite systems for communications and navigation. Concept/Framework Mesh Satellite Network Mesh Satellite Network is a satellite architecture in which satellites are interconnected through multiple communication paths. It supports distributed routing and resilience in space. Concept/Framework Microwave Link A microwave link is a directional wireless communications path that uses microwave frequencies to connect two fixed endpoints. It typically forms a transport link for backhaul, intersite connectivity, or critical… Concept/Framework Mission Assurance Mission Assurance is the practice of ensuring that mission objectives can be achieved with acceptable risk across design, operations, and recovery. Operations Modulation Modulation is the method of varying a carrier’s amplitude, frequency, phase, or related properties to represent information for transmission. It is the bridge between digital or analog information and physical… Concept/Framework Momentum Wheel A momentum wheel is a wheel used to store angular momentum and provide attitude stability or control torque in a spacecraft, enabling controlled orientation without propellant consumption. Hardware Multi Orbit Architecture Multi Orbit Architecture is a space communications design that uses satellites in more than one orbital regime to deliver or support service, combining the strengths of different orbit classes. Service Model Multipath Multipath is a radio propagation phenomenon in which transmitted energy arrives at the receiver over multiple reflected, refracted, or scattered paths. The resulting interference can change the observed signal quality. Concept/Framework Navigational Warning Dissemination Navigational Warning Dissemination is the distribution of Maritime safety warnings and notices to vessels and operators. It provides navigational hazard information to inform operational decision-making and route adjustments. Service Model
