The technical system requirements documented in the System Specification stay on mission level: System functions and performances, Orbit, Launch vehicle, etc. [citation needed] Non-technical system (task) requirements: Cost and progress reporting, Documentation maintenance, etc. The customer (requirements) specification is answered by the ...
Identification, friend or foe ( IFF) is a combat identification system designed for command and control. It uses a transponder that listens for an interrogation signal and then sends a response that identifies the broadcaster. IFF systems usually use radar frequencies, but other electromagnetic frequencies, radio or infrared, may be used. [1]
A built-in self-test ( BIST) or built-in test ( BIT) is a mechanism that permits a machine to test itself. Engineers design BISTs to meet requirements such as: or constraints such as: The main purpose [1] of BIST is to reduce the complexity, and thereby decrease the cost and reduce reliance upon external (pattern-programmed) test equipment.
Track while scan. Track-while-scan ( TWS) is a mode of radar operation in which the radar allocates part of its power to tracking a target or targets (up to forty with modern radar) while part of its power is allocated to scanning. It is similar to but functions differently in comparison to its counterparts range-while-search (RWS), long range ...
A cognitive radio (CR) is a radio that can be programmed and configured dynamically to use the best channels in its vicinity to avoid user interference and congestion. Such a radio automatically detects available channels, then accordingly changes its transmission or reception parameters to allow more concurrent wireless communications in a given band at one location.
The process of entering safe mode, sometimes referred to as safing, [3] involves a number of immediate physical actions taken to prevent damage or complete loss. Power is removed from non-essential subsystems. Regaining attitude control, if lost, is the highest priority because it is necessary to maintain thermal balance and proper illumination ...
Functional safety. (Redirected from Functional Safety) Functional safety is the part of the overall safety of a system or piece of equipment that depends on automatic protection operating correctly in response to its inputs or failure in a predictable manner ( fail-safe ). The automatic protection system should be designed to properly handle ...
The air traffic control radar beacon system ( ATCRBS) is a system used in air traffic control (ATC) to enhance surveillance radar monitoring and separation of air traffic. It consists of a rotating ground antenna and transponders in aircraft. The ground antenna sweeps a narrow vertical beam of microwaves around the airspace.
