The problem of interference

The Satellite Users Interference Reduction Group (SUIRG) was formed in 1997, and in 2011 was renamed as the Satellite Interference Reduction Group (IRG). The group was jointly-established by Inmarsat, Intelsat, PanAmSat, QinetiQ, Glowlink and SES World Skies in order to combat and mitigate radio frequency (RF) interference to enable smooth satellite communications. Interview with Martin Coleman, Executive Director of the iRG, to find out more about the group’s view of the sector, its recent accomplishments, and its outlook for the future…Read...

A case of radar interference

Interference is a major concern for much of the satellite industry, particularly for users who rely on it for mission-critical communications and data needs. As such, the Satellite Interference Reduction Group (IRG) goes to great lengths to bring together those throughout the service chain to prevent and act upon interference in all guises. It’s certainly true that not all cases are simple. John Lee, Principal RF Engineer of Intelsat, outlines one particularly challenging case of RADAR interference, and the path taken to resolve it…   Read more page...

Innovation the key word in combating satellite interference. By Martin Coleman

The life of a satellite broadcaster has not been running smoothly over recent years. Most people will be aware of the battle of the spectrum this year, where valuable satellite spectrum, mostly used by broadcasters, has been once again under threat from the mobile industry. Add to that the threat from satellite interference, including intentional, potentially impacting those all-important broadcasts, it must feel a little doom and gloom out there. However, there is definitely light at the end of the tunnel and it comes in the form of innovation! Read...
