There are countless reasons why a corporate aircraft operator would choose to install Iridium SATCOM voice. Some may be driven by operational needs, regulatory mandates, route structure, or current aircraft communication gaps. If your mission profiles take you away from VHF voice communication, it is imperative that you have either SATCOM or HF for Long-Range Voice Communication.
Iridium SATCOM is also ideal for datalink communication including ACARS, FANS 1/A, CPDLC and ADS-C. There are many corporate aircraft using Iridium to fly the North Atlantic tracks. These aircraft are using FANS over Iridium to achieve reduced separation between aircraft, as well as lower flight times and reduced fuel consumption. This is primarily due to the use of better winds, while maintaining and increased level of safety and communication.
Iridium SATVOICE is operationally more effective, it costs 30-50% less than HF, is global and the voice quality is consistently clear and reliable. HF, on the other hand, can often be unreliable or of poor quality. This is due to effects from the sun, weather or geography. Iridium SATCOM reduces channel congestion, pilot errors, and flight delays.
From a technical perspective, the benefits of Iridium over HF include 450-650W savings in power consumption, no cooling requirement, higher voice quality and reliability, 20-50 man-hour savings in retrofit time, and smaller antenna and equipment which result in more flexible space allocation for installation, and approximately 50kg in weight savings.
