ADS-B is the next generation air traffic surveillance system to broadcast automatically flight information, such as aircrafts’ position, altitude and speed, without pilot’s intervention. The data in this system are particularly transmitted every second amongst aircrafts and ground stations; thus, ADS-B can improve ATS (Air Traffic Service) and pilots’ situational awareness remarkably.
- - Air Traffic Services (ATS) improves
- - Improve situational awareness of pilots of Air Traffic
ADS-B has two functions, ADS-B OUT and ADS-B IN. ADS-B OUT is air-to-ground and ground-to-ground data communication
function by aircrafts’ broadcast, and ADS-B IN is air traffic information reception function by CDTI (Cockpit Display of Traffic Information) for pilots.
Particularly, ADS-B GS (Ground Station) provides the aircrafts having no ADS-B OUT function with ADS-B IN service through TIS-B (Traffic Information
ADS-B ground system consists of 1090ES or UAT GS, ADS-B/TIS-B/FIS-B server and monitoring equipment. ADS-B GS sends air surveillance data to ADS-B server and receives air traffic information from TIS-B/FIS-B server. On the other hand, ADS-B airborne or vehicle unit transfers navigational data to other aircrafts and ADS-B GS and displays other surrounding aircrafts’ flight information to pilots through CDTI.
Our work on the ADS-B system contains equipment development, system integration and operation test, and our system architecture and services are as follows.
- - Mounted equipment or portable CDTI
- - UAT ADS-B Ground equipment
- - 1090ES ADS-B Ground equipment
- - ADS-B Monitoring equipment
- - ADS-B/TIS-B/FIS-B Server
