A classified SpaceX Starshield network broadcasts on command frequencies, raising interference and regulatory concerns.
A classified network of SpaceX Starshield satellites, operated by the U.S. National Reconnaissance Office, is emitting signals on radio frequencies normally used for sending commands from Earth, not receiving data from space, raising concerns about interference with other satellites.
Detected by Canadian amateur tracker Scott Tilley in March 2025, the signals originate in the 2025–2110 MHz band—reserved for uplinking—and come from at least 170 Starshield satellites launched since May 2024.
Experts say the transmissions could disrupt other systems, though actual impact is unclear.
The signals shift frequencies and may be used to obscure operations.
The Starshield program, part of a military-focused, proliferated satellite system, aims to enhance rapid data access, communications resilience, and Earth observation.
SpaceX and the NRO have not commented.
The use of this spectrum may violate International Telecommunication Union rules.
