- SpaceX built 170 Starshield satellites for the US National Reconnaissance Office (NRO).
- Satellites are emitting signals in the wrong direction, using a frequency band meant for Earth-to-space and space-to-space transmissions.
- No public complaints of interference have been reported, but the signals raise concerns about lack of transparency and international coordination.
- Amateur radio astronomer Scott Tilley discovered the signals in the 2025–2110 MHz band, affecting Canada, the US, and Mexico.
- The signals could interfere with satellite receivers, impacting NASA, NOAA, and other users of the S-Band frequency.
- The purpose of these signals remains unknown, highlighting potential issues in spectrum management.
