2 /06/2005 direction générale de l’Aviation civile direction des services de la Navigation aérienne direction de la Technique et de l’Innovation ADS-B out : Statement of issue ADS-B out : Broadcast of identification, position, altitude, velocity, Navigation integrity data by the aircraft –1090 ES technology –Used initially for radar-like surveillance service by ATC Part of ADS-B Package 1 application : ADS-B NRA, ADS-B ACC, ADS-B TMA, ADS-B APT, ADS-B ADD Ground stations are easy to install and much cheaper than radar ADS-B separation standard under definition by ICAO SASP –5 Nm separation already approved by Australia under specific conditions –Simple installation in the aircraft : transponder + GNSS receiver –Currently under implementation : Australia, US, France (La Réunion Island), CASCADE program in EUROCONTROL Stream 1 : Mediterranean project

3 /06/2005 direction générale de l’Aviation civile direction des services de la Navigation aérienne direction de la Technique et de l’Innovation ADS-B Installation Many aircraft are already fitted with ADS-B capabilities –Many Mode S transponders for Enhanced surveillance are capable of ADS-B –No certification of ADS-B data, only non interference considerations –Guidance material is needed Initial results from Toulouse validation trials –Excellent detection range (200 Nm, up to 250 Nm) –Various quality of aircraft installation NUC = 0 often observed Aberrant case observed –Eg NUC = 8 with impossible shift of transmitted position Specific cases will be analysed case by case –Increasing number of equipped aircraft Peak of 53 ADS-B aircraft at the same time detected by the ground station in Toulouse
