VSAT Very Small Aperture Terminal
A very small aperture terminal ( VSAT ) is a two-way satellite ground station with a dish antenna that is smaller than 3.8 meters. The majority of VSAT antennas range from 75 cm to 1.2 m. Data rates, in most cases, range from 4 kbit/s up to 16 Mbit/s. VSATs access satellites in geosynchronous orbit or geostationary orbit to relay data from small remote Earth stations (terminals) to other terminals (in mesh topology) or master Earth station "hubs" (in star topology).
RADIO LINK
A radio link is a wireless connection (also called wireless Point-to-Point connection) between two nodes, or radio units, in a data network.
ACARS: Aircraft Communications, Addressing and Reporting System
ACARS is a digital data link system for the transmission of messages between aircraft and ground stations, which has been in use since 1978. At first it relied exclusively on VHF channels but more recently, alternative means of data transmission have been added which have greatly enhanced its geographical coverage. There has also been a rapid trend towards the integration of aircraft systems with the ACARS link. Both have led to rapid growth in its use as an operational communications tool. Modern ACARS equipment now includes the facility for automatic as well as manual initiation of messaging. ARINC guidelines have been defined for all the various avionic components of ACARS.
ADEXP (ATS Data Exchange Presentation)
ADEXP is a format, not a protocol. No restrictions are imposed on the transmission media or protocols to be used, other than that of the character set. ADEXP provides a format for use in on-line, computer to computer message exchange and for message exchange over switched messaging networks (e.g. AFTN, CIDIN, AMHS).
Radar Terms
Term Meaning Azimuth : Angle along the earth horizon Bearing : Angle along the artificial horizon (deck) Elevation : Angle above or below the horizon Range : Distance along the plane established by the horizon Slant Range : Distance along the true line of sight True : Angle in earth coordinates with true north as the reference Relative : Angle in deck-plane coordinates using vehicle heading as the reference Rectangular : Cartesian coordinates typically known as X, Y, and Z Spherical : Polar coordinates typically known as range, bearing, and elevation
Leonardo 2017 World Air Traffic Management (ATM) Congress in Madrid
Leonardo’s air traffic control innovations are on show at the 2017 World Air Traffic Management (ATM) Congress in Madrid "Leonardo has also been shortlisted for the Jane’s ATC Awards 2017, taking place during the Show (7th March), in the “Technology Award - reflecting a significant contribution by equipment and systems suppliers” category, for its comprehensive modernisation of ATM systems under Turkey’s SMART (Systematic Modernisation of ATM Resources in Turkey) project now underway, aiming to enhance the country’s ATC infrastructure and services."
BADA - Base of Aircraft Data
The Base of Aircraft Data (BADA) is an Aircraft Performance Model (APM) developed and maintained by EUROCONTROL, with the active cooperation of aircraft manufacturers and operating airlines. The BADA APM is designed for simulation and prediction of aircraft trajectories for purposes of ATM research and operations. Aircraft performance parameters and trajectories can be calculated using information and data contained in BADA. To replicate reality in both operational and research modelling and simulation systems, each and every real aircraft needs a corresponding aircraft model.

EOBT-TOBT-TTOT-TSAT-CDM
EOBT is Estimated Off Blocks Time : The flight plan time for the flight to be ready for departure. ATC usually allow a tolerance of +/- 15 minutes. TOBT, Target Off Blocks TIme , is a more accurate measure, usually within +/- 5 minutes, which tells the local CDM system and NMOC Brussels when the airline believes a flight will be ready. From this, a TTOT is calculated (Target Take Off Time) , which may be adjusted to allow for departure separations, CTOT etc, and then working backwards will provide a TSAT (Target Start Approval Time) which will provide both ATC and the airline the most suitable start up time given all the factors that the local CDM system takes into account.
ASTERIX (ATC standard)
ASTERIX (short for All Purpose Structured Eurocontrol Surveillance Information Exchange ) is a standard for the exchange of air traffic services (ATS) information. It is developed and maintained by the European ATS organization Eurocontrol . ASTERIX not only stands for All-Purpose Structured Eurocontrol Surveillance Infor mation Exchange but also represents a state-of-the-art surveillance data format which is nearly being adopted by the world users community as the universal standard in this domain today
ARTAS (ATM SuRveillance Tracker And Server)
ARTAS is a system designed by Eurocontrol in order to help in Aerial surveillance and Air traffic control . It can establish an accurate Air Situation Picture of all traffic over a well-defined geographical area (e.g. ECAC ), and to distribute the relevant surveillance information to a community of user systems.
Phoenix (ATC)
PHOENIX is a multipurpose Radar Data Processing System(RDPS) / Surveillance Data Processing System (SDPS) - a.k.a. tracker - used for many ATC applications in the Deutsche Flugsicherung (DFS), and is continuously extended and maintained ever since. PHOENIX is also foreseen as a fundamental component for all future ATM systems in the DFS into the 2020s and part of the DFS initiative for “ATS componentware” in the European SESAR programme.
