The functions of CNPC can be related to different types of information such as: telecommand messages, non-payload telemetry data, support for navigation aids, air traffic control voice relay, air traffic services data relay, target track data, airborne weather radar downlink data, non-payload video downlink data.
The planned introduction of unmanned aircraft (UA) systems (UAS) into non-segregated civil airspace will require highly reliable radio links to enable remote pilots to maintain operational control and ensure safe operation. The safety-critical functions of those control and non-payload communications (CNPC) links distinguishes them from “payload” links (e.g., area-surveillance data downlinks) that, although essential to UAS missions, are not needed for piloting.
Use of radio-frequency spectrum for RPAS links has to be approved by the ITU, which in 2009 calculated spectrum requirements for Control and Non-Payload Communications (CNPC) as: ● Line-of-sight (LOS) — terrestrial systems: 34 MHz ● Beyond line-of-sight (BLOS) — satellite systems: 56 MHz.
