SATCOM refers to both data and voice communications via satellite. SATVOICE refers to voice communication only.
The International Civil Aviation Organization (ICAO)) decided in the 1990s that future primary long-range communications with aircraft would be by:
- high frequency (HF)
- SATCOM data link.
ICAO didn't make any provision for SATCOM Voice (SATVOICE). The transition to data link communications also didn't happen.
HF voice communications is still a primary means of long-range communication. ICAO Standards and Recommended Practices (SARPs) does not recognise SATVOICE as an acceptable means of communication for air traffic services (ATS) purposes.
Using SATVOICE
Some States have allowed SATVOICE use instead of carrying a second HF communications system. This is only for when the aircraft installation and ground segments of the system meet certain performance standards. These must provide a level of assurance that the system will perform at an acceptable level.
ICAO recognises SATVOICE as a valid means of communication. Satellite Voice Guidance Material (SVGM) is developed and approved by the:
- ICAO Asia/Pacific Air Navigation Planning and Implementation Regional Planning Group (APANPIRG)
- North Atlantic Systems Planning Group (NAT SPG).
Status in Australia
SATVOICE is not authorised for ATS use in Australia. This is because the Airservices Australia communications infrastructure does not support SATVOICE operations.
SATVOICE won't be available for ATS use in Australia for the foreseeable future. The exception is where provided for in the Aeronautical Information Publication (AIP).
You can use SATVOICE in North Atlantic High Level Airspace (NAT HLA) when authorised by us.
