A recent discovery by a Canadian satellite researcher has raised concerns that a fleet of US spy satellites, built by SpaceX, may be broadcasting signals in the wrong direction. The 171 Starshield satellites, operated by the National Reconnaissance Office (NRO), were found to be using a frequency allocated for space-to-space transmissions, potentially disrupting Earth-based communications and broadcasts.
The International Telecommunication Union (ITU) has designated the 2025-2110 MHz band as an uplink band for spacecraft on orbit. However, with a loud constellation of signals broadcasting on the same frequencies, it can interfere with ground station signals directed at satellites in space.
This issue could have significant consequences, including disrupting important broadcasts from orbit and interfering with TV transmissions. The researcher emphasized that any other radio activity on this band is intentionally limited to avoid causing disruption to its primary purpose. Despite no overt disruptions reported, the incident highlights the importance of monitoring satellite operations and ensuring they do not interfere with critical communications systems.
