Conclusions and Limitations
> Lecture > Author • Document > DateDLR.de • Chart 12
Automatic Dependent Surveillance Broadcast
➢ Concurrent Technologies:- 1090ES (Extended Squitter), most common (European ADS-B-Mandate, FAA’s ADS-B Final Implementation Rule)- UAT 978 MHz (only US, but proposed for STM by FAA)
➢ Limitations:- Barometric Altitude - limited to 101,337.5 ft (30,888 m)→ New message encodings needed- COCOM limitations → ITAR limitations of GPS:Faster than 1,000 knots and/orAltitude >59,000 ft (18,000 m)
