Garmin International announced last week that it has joined a broad aviation industry coalition in urging the Federal Communications Commission (FCC) to reconsider its “Report and Order” to repurpose C-band frequency spectrum nearby to the frequency band that is used by safety-critical FAA-certified radio (radar) altimeters, including Garmin’s GRA 5500 and GRA 55. Joining Garmin to express concerns were a coalition of “aviation petitioners” that also included the Aerospace Industries Association, the Aerospace Vehicle Systems Institute, the Air Line Pilots Association, Airbus, Aviation Spectrum Resources, the General Aviation Manufacturers Association, Helicopter Association International, Honeywell International, the International Air Transport Association, and the National Air Transportation Association.
Garmin Joins Coalition to Protect Radio Altimeters From 5G Interference
Key Takeaways:
- Garmin and a broad aviation coalition are urging the FCC to reconsider its C-band spectrum repurposing decision, citing concerns about potential harmful interference with safety-critical FAA-certified radio altimeters.
- Radio altimeters, essential for safe aircraft operations, particularly in poor weather, operate in a frequency band adjacent to the newly allocated C-band spectrum for flexible use, including 5G.
- The coalition is not against repurposing the C-band but seeks a solution that ensures full protection of altimeters, arguing the current FCC order unfairly places the burden of preventing interference on the aviation industry.
