AIBriefOct16,2003.ppt 4 What IS this thing? AIRBORNE INTERNET What IS this thing? (and what it is NOT) A private, secure and reliable peer-to-peer aircraft communications network that uses the same technologies as the commercial Internet. A general purpose, multi-application data channel for transportation * It is NOT the World Wide Web ! *

AIBriefOct16,2003.ppt 18 Radar dependant airspace. Radars are installed as airspace traffic density increases (e.g. NE U.S.) Current System:Technology: -Analog technology foundation -Dual function transponder -Line of sight -Provide aircraft altitude, range, ID code -Extensive processing can provide flight trend prediction Goal -Flight coverage is geographic dependant - Low altitude gaps -Many GA airports not covered A.I. Application Example: Surveillance Radar Augmentation Outside of radar coverage ATC has no positive knowledge of A/C position, altitude, etc. - Use checkpoint reporting A/C tracking depends on secondary surveillance radar Transponders in A/C reply to ground interrogations from surveillance radars. ATC has positive knowledge of A/C position, altitude, etc. Limitations: B B
