Although interference only affects a minor number of services, it does cost the satellite industry as a whole as a great deal of manpower has to be given over to discovering its causes. RF interference is often caused by human error, bad installation, lack of training, poor equipment or system design and a lack of adherence to industry standards and guidelines. Occasionally, interference may be malicious, but this is rare and the main issues of interference lie largely within the heart of the satellite industry itself. The orbital spacing of satellites is being reduced and the fill rate is getting higher. With more LEO and MEO constellations both planned and already in place, it is getting crowded up there and, without due diligence by the industry, will lead to increased interference.
The Satellite Interference Reduction Group (IRG) aims to keep interference under tight control.
