SpaceX's classified Starshield satellites are emitting mysterious signals on frequencies reserved for uplinking data from Earth to satellites, potentially violating international standards.
Amateur satellite tracker Scott Tilley discovered the signals accidentally, noting they could interfere with other satellites' operations.
The signals are in the 2025-2110 MHz range, which is unusual for downlinking data from space.
Starshield, a classified version of Starlink, is used for Earth observation and communications, with the U.S. investing over $1.8 billion in the network.
The purpose of the signals is unclear, but theories include hiding operations or utilizing a quiet part of the spectrum.
Experts suggest the signals may not have caused significant disruptions yet, but Tilley warns of potential risks to legitimate space uses.
