Satellite communications industry has been growing rapidly over recent years. There has never been more satellite launches than we have had in the last two years with all the LEO launches. Diversity of satellites, new transmission modes and optimization techniques combined with proprietary standards is all adding complexity to an already challenging environment. As the number of satellites increases, it is expected that the number of interference cases increases as well. This leads to a significant higher amount of effort for satellite operators to identify interference cases.
AI has the potential to be a game changer in the satellite industry, where it could be used to improve processes and increase efficiency. AI could establish a digital assistant, capable of processing information about everyday satellite procedures, resolving and predicting issues before they become errors.
