Question

what is components ATC system?

Answer 1

MAIN COMPONENTS OF ATC SYSTEM :

• Surveillance Radar: There are two types of radars primary surveillance radar and secondary surveillance radars. Primary radars determine range and bearing from the aircraft structure. Secondary surveillance radar, is able to obtain, in addition to range and bearing, the aircraft’s identity and altitude. Secondary radar is the principal surveillance tool for the ATC system.
• Airborne Transponders:Transponders are radio transmitters that are designed to respond to ground interrogation. They have a strong signal which is easily differentiated from a reflective return. The ground equipment and airborne transponders together constitute the ATCRBS.Tthese transponders have the ability to transmit one of 4,096 different identity codes to a Mode A query made by ATCRBS interrogator.
• Navigation aids: These are another important element of the ATC system that influence the structure and the operation of the system. These aids operates in the VHF band below the frequencies which are used for voice communication.
• Computers: Computers are extensively used throughout the ATC system. They help in processing flight plans, correlating radar and transponder returns, filtering out extraneous signals, and generating displays on the controller’s console.
• Communication: It is a key element in the present ATC system. It advances communication technology that may open new options for configuring the system. Digital communication sytems help in the transmission of data in the form of binary signals that are used for linking ground stations.
