L Band L Band is a lower microwave frequency range used in communications and navigation systems, valued for propagation characteristics and broad service support. Hardware LDACS An emerging aeronautical datalink standard being developed to provide enroute air-ground data communication capacity in the L-band frequency range, addressing anticipated future capacity constraints as datalink-dependent air traffic management continues… Protocol 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. Hardware Mission Assurance Mission Assurance is the practice of ensuring that mission objectives can be achieved with acceptable risk across design, operations, and recovery. Operations Mode S A secondary surveillance radar transponder protocol that assigns each aircraft a unique address, letting ground radar interrogate a specific aircraft individually, and supporting unsolicited periodic broadcast of aircraft data through… Protocol Multilateration A surveillance technique that determines an aircraft's position by measuring the time difference of arrival of its Mode S transponder replies at multiple ground receiver stations, calculating position from those… Concept/Framework Onboard Networking Onboard networking is the set of internal network connections and control functions that distribute data among systems on a platform such as an aircraft. It links sensors, payloads, processing systems,… Concept/Framework Propellant Tank Propellant Tank is a container that stores fuel or propellant for a propulsion system or spacecraft subsystem, providing contained storage for consumable fluid while maintaining operational pressure and flow conditions. Hardware Reaction Wheel Reaction Wheel is an attitude control device that changes a spacecraft's orientation by accelerating or braking an internal spinning mass, providing propellant-free pointing control through conservation of angular momentum. Hardware Regulatory Coordination Regulatory Coordination is the process of aligning technical or operational plans with applicable regulatory requirements, supporting approvals, licensing, and compliance across jurisdictions and authorities.
