Note: cabin SATCOM operates in Ku/Ka band radio frequency. For continental areas such as Europe, VHF is mainly used thanks to a widely deployed, but increasingly congested, VHF ground network. Initially performed exclusively with HF voice communication, the cockpit SATCOM which operates in the L-band radio frequency is now recognized as an alternative means of communication with the ATC (Air Traffic Control) or AOC (Airline Operation Centre). Since the early stages of commercial aviation, and in order to enhance safety, regulations have required long-range communication means for flying over oceanic and remote areas. The Light Cockpit SATCOM (LCS) provides a solution, using IP technology as well as stringent data security barriers in accordance with regulations. However, whilst airlines need and expect more connected IP-based applications, it is fundamental to ensure aircraft systems remain protected. Today, satellite constellation technology enables more throughput, taking into account regulation requirements and the growing number of customers.
A320 COCKPIT UPDATE
Evolving user requirements and technology have led Airbus to review and update the system. Pilots and ground staff rely on the cockpit SATCOM as an essential means to communicate.
