“…Up to five offset frequencies are used for each control sector according to the ICAO annex 10, the different audio signal coming to/from the remote sites are integrated in a best signal selection system in order to choose the best reception audio and send it to the air traffic control personnel [3]. This implies that the transmission media for transmits the information from the ACC to the sites could be microwave links of fiber optics or satellite links, this causes some issue related to the delay time in the transmission that could be causes echoes in the audio that come to the aircrafts crews [9].…”

“…The Colombian Air Navigation Service Provider wants migrates the operational data traffic (Air/Ground and Ground/Ground voice, radar traffic, and meteorological data) to an IP backbone. However, this need to make the migration must be gradual to assure a smooth transition, mainly because the actual networks are based in analogue interfaces for telephony (FXO,FXS) and radio (4W E&M), and other data sources are legacy (HDLC, RS232, X.25) [1,2,9].…”

“…Also the size of the air space needs to cover big areas with VHF voice communications systems for the aeronautical mobile services. The need of a satellite networks is justified for this two major reasons [9].…”

This paper presents the design, implementation and performance validation of an Aeronautical Telecommunications Network (ATN) based on IP standards and protocols comply on ICAO specifications as described in DOC 9896 manual, using a VSAT satellite links like carrier technology. The design of the network follows the operational concept and requirements defined for the CAA in Colombia. The network includes ground to ground and ground to air, radio and telephony VoIP services with the use and requirements of the EUROCAE ED-137 normative. Also ground to ground applications like AMHS, radar surveillance data and remote radio control services are supported for the ATN. The paper shows the design and implementation of the network and summarizes the methodological process used for it, taking in account key aspects like: coverage regions and ATC control sectors, medium access to the satellite, bandwidth utilization and optimization by mean of G.729 compression algorithm, number of station and interfaces for each service and permissible delays for the VoIP and data applications. Special emphasis, in the design and implementation stages, is made to the use of VoIP (ED-137) in a environment of radios in VHF extended range operation given a particular conditions of the ATC controls sectors that use different communications media (terrestrial links and satellite links) to communicate the ATC control centers and the remote stations.Finally, this paper summarizes the methodological process used for the validation of the network in a real time operational environment, resuming the final results and conclusions of the implementation stage and the future work is established.

This paper presents the modeling and simulation of a Very High Frequency Data Link Mode 2 (VDL2) sub network to support Controller Pilot Data Link Communication (CPDLC), at El Dorado International Airport in Bogota City. The modeling and simulation were made in order to determine performance characteristics and determine if VDL2 could meet future traffic load increase. The simulation was performed using Network Simulator 2 (NS2). An overview of the technologies currently used for air-ground communication in Colombia ispresented. Also this paper shows a glimpse of the features of the VDL Mode 2 protocol and CPDLC service. The VDL Mode 2 subnet model and the subsequent simulation were derived from the characteristics of Colombian airspace and air traffic conditions in the Bogota Terminal Area (TMA). Finally, the simulation results are presented.
