Communication Systems

This module is common with the equivalent module from AGCSE Master - AVI11 Communication Systems


This formation covers the analysis of the aeronautical communication requirements (Air Traffic Management, Aircraft operation and passenger communications) , the current technical solutions and their evolutions requiring new innovative technical solutions.


Engineers and executives.


Basic knowledge in communication networks.


1. Introduction , History , context of the Aeronautical communications.

This course deals with in particular :

  • The air/ground voice communications, the current technologies (25 kHz, 8.33 kHz, HF voice, Satellite voice) and their evolutions.

  • The current Datalink technology based on ACARS (Airline Communication, Addressing and Reporting System) protocols and the key applications of the ATM domain,

  • ATN (Aeronautical Telecommunication Network) that makes up the air/ground common data transport layer,

  • The various sub-networks that could be inter-connected through the ATN : VDL mode 2 , Satellite D/L , HF D/L,

  • The main air/ground data-link services (or applications) that have been defined at ICAO level (CPDCL, ADS, ..) and their deployment foreseen in Europe (Link 2000+ programme),

  • The evolution of the key ground/ground data communications services in the perspective of usage of native IP network service,

  • The topics of “Radio Spectrum Management” will be also explored,

  • Hands-on in aeronautical communications that will be covered in course , will be organised.

2. Voice communications : Case study , en route VHF coverage :
  • VHF and HF physical characteristics.

  • Operational constraints.

3. Data communications :
  • ACARS , ARINC 622/623 evolution . Description and application.

  • AMSS sub-network.

  • HF sub-network.

  • SATCOM sub-network , future component sat-com in L Band ) and Hands-on.

4. Ground Telecom Service over IP :
  • Deployment of Internet Protocol (IP) : the future based networks in aviation.

  • Data sharing information : System Wide Information Management (SWIM Concept) .

5. Spectrum Management
6. Overall system of means of communications , integration Onboard :
