Air traffic controllers (ATCs) are people responsible for the coordination of traffic in their assigned airspace.Typically stationed in air traffic control centers or control towers, they monitor the position, speed, and altitude of aircraft and communicate with the pilots via radio.
The AN/TPS-80 Ground/Air Task Oriented Radar (G/ATOR) is the United States Marine Corps next-generation Air Surveillance/Air Defense and Air Traffic Control (ATC) Radar. The mobile active electronically scanned array radar system is being developed by Northrop Grumman and was expected to reach initial operating capability in August 2016.
D-ATC indicator used on the E233 series trains. The digital ATC system uses the track circuits to detect the presence of a train in the section and then transmits digital data from wayside equipment to the train on the track circuit numbers, the number of clear sections (track circuits) to the next train ahead, and the platform that the train will arrive at.
Squadrons quickly had special chutes fitted to their bombers to make chaff deployment even easier. Seeing this as a development that made it safer to go on operations, many crews got in as many trips as they could before the Germans found a counter-countermeasure. The effect of chaff on the display of a Würzburg Riese radar. The effect of ...
ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno, Arduino Pro Mini [4] and Arduino Nano models.
The Toronto subway uses a variety of signalling systems on its lines, consisting of a combination of fixed block signalling and moving block signalling technologies.. The oldest signalling system is known as automatic block signalling and was designed for the system's heavy rail lines: Line 1 Yonge–University, Line 2 Bloor–Danforth and Line 4 Sheppard.
Begin using briefed radio procedures to counter communications jamming. Cheapshot (USAF) Active missile supported to high pulse repetition frequency (HPRF, better against oncoming targets), but not medium pulse repetition frequency (MPRF, better against targets flying away). (Naval) Active missile not supported to active range. Check turn (deg)
Not all towered airports have 24/7 ATC operations. In those cases, non-towered procedures apply when the tower is not in use, such as at night. Non-towered airports come under area (en-route) control. Remote and virtual tower (RVT) is a system in which ATC is handled by controllers who are not present at the airport itself.
