Colombian airline Avianca Airlines is installing Iridium-based satLINK Communications Module on its fleet of 14 long-range Boeing 757 and 767 aircraft. The system, made by Miami-based Avionica, includes antenna, wiring, structural elements and a control panel providing voice communications worldwide, GPS data over TCP/IP, dedicated voice and data channels and programmable traffic routing. "South America’s topography causes HF signal reflections which lead to gaps in service availability,” said Raul Segredo, president of Avionica. “During inclement weather, these gaps restrict non-stop flights, resulting in delays as well as increased technical and labor costs.” Segredo added the satLINK system, along with Iridium’s global coverage, eliminates the interruptions in cockpit communications.
