Automatic Dependent Surveillance-Broadcast>>>ADS-B

Abstract

The most important objective in this research is ADS-B supports improved use of airspace, reduced ceiling/visibility restrictions, improved surface surveillance, and enhanced safety such as conflict management.

ADS-B is automatic in the sense that no pilot or controller action is required for the information to be issued. It is dependent surveillance in the sense that the surveillance-type information so obtained depends on the suitable navigation and broadcast capability in the source vehicle.

The conclusion of this research is how a aircraft periodically broadcasts its own state vector and other information without knowing what other aircraft or entities might be receiving it, and without expectation of an acknowledgement or reply, to aim the goal of reducing the work-load from the controller and efficiency of the national airspace (NAS) .

Introduction

In the beginning of the air traffic control the controllers were working without any technology and without using radar (non-radar), then and during the Second World War the radar appeared and it was only using for the military purposes after this time the primary radar used in the civil aviation and after the period of time the air traffic control working with the secondary radar which is more accurate than the primary and after the applying of secondary surveillance radar (SSR) the new step is to using the satellite system in the civil aviation field and one of this satellite applications is ADS-B integrated with the GPS .

GPS based technologies that promise a substantial change in airborne communication, navigation and surveillance techniques, are nearing fruition; among these is Automatic Dependent Surveillance – Broadcast [ ADS-B].

The system concept is that all, or most, aircraft in an area automatically and continually (i.e. roughly once per second) broadcast, or squatter, several digital data packets which together contain the aircraft's 24 bit address [unique airframe identification], flight identification [call sign], GPS derived latitude and longitude, barometric [or Mode C] altitude plus 3 dimensional velocity, i.e. rate of climb/descent, direction and speed.

The broadcast data packets from aircraft are received by ATC ground stations which can feed the data to air traffic management systems, for even more precise tracking than with radar.

The broadcast ADS-B packets can also be received by aircraft equipped with an ADS-B data receiver
The derived data provides a real time cockpit display of traffic information; Similar to the ground air traffic management systems except that the traffic is shown in relation to aircraft's intended track.
