Mission Assurance Mission Assurance is the practice of ensuring that mission objectives can be achieved with acceptable risk across design, operations, and recovery. Operations Mobility Mobility is the capability for a connection, service, or device to remain usable as the endpoint changes location. Concept/Framework 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 Multi-Orbit Connectivity A satellite service model in which a user terminal or network connects through more than one orbital class — LEO, MEO, or GEO — either simultaneously or by switching between… Concept/Framework 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 New Radio The 3GPP-specified air interface for 5G, defining the physical layer waveform, flexible numerology, and radio protocol stack (PHY, MAC, RLC, PDCP) that terrestrial base stations and non-terrestrial network payloads alike… Protocol NTN Cell The 3GPP-recognized radio coverage area served by a non-terrestrial network node, defined by a Cell ID and system information broadcast, within which user equipment performs cell selection, camping, and connection… Concept/Framework
