Conceptual of the ADS-B system, illustrating radio links between aircraft, ground station and satellite. Automatic Dependent Surveillance–Broadcast (ADS-B) is an aviation surveillance technology and form of electronic conspicuity in which an aircraft determines its position via satellite navigation or other sensors and periodically broadcasts its position and other related data, enabling it ...
Upon interrogation, Mode S transponders transmit information about the aircraft to the SSR system, to TCAS receivers on board aircraft and to the ADS-B SSR system. This information includes the call sign of the aircraft and/or the aircraft's permanent ICAO 24-bit address (which is represented for human interface purposes as six hexadecimal ...
The application is known as ADS-C (automatic dependent surveillance, contract). In this system, an air traffic controller can set up a "contract" (software arrangement) with the airplane's navigational system, to automatically send a position report on a specified periodic basis – every 5 minutes, for example.
The TN 70 is a French-built thermonuclear warhead which was used on submarine-launched ballistic missiles in Redoutable class ballistic missile submarines.. It has a yield of 150 kt.
A triangulation station, also known as a trigonometrical point, and sometimes informally as a trig, is a fixed surveying station, used in geodetic surveying and other surveying projects in its vicinity.
Orthodromic course drawn on the Earth globe. Great-circle navigation or orthodromic navigation (related to orthodromic course; from Ancient Greek ορθός (orthós) 'right angle' and δρόμος (drómos) 'path') is the practice of navigating a vessel (a ship or aircraft) along a great circle.
The apparent magnitudes of stars in the system are often used to determine the color indices B−V and U−B, the difference between the B and V magnitudes and the U and B magnitudes respectively. [1] The system is defined using a set of color optical filters in combination with an RMA 1P21 photomultiplier tube. [2]
At Cambridge, a tutorial is known as a supervision. In Australian, New Zealand, and South African universities, a tutorial (colloquially called a tute or tut) is a class of 10–30 students. Such tutorials are very similar to the Canadian system, although, tutorials are usually led by honours or postgraduate students, known as 'tutors'.
