Given the global nature of the Starshield constellation, it is possible that the signals are also being emitted over other countries.<\/p>\n\n\n<p class=\"wp-block-paragraph\">&#8220;This particular band is assigned by the ITU [International Telecommunication Union], primarily by the United States and Canada, as an uplink band for spacecraft in orbit, that is, objects in space, so satellite receivers will listen to these frequencies,&#8221; explained Tilley <a href=\"https:\/\/arstechnica.com\/tech-policy\/2025\/11\/us-spy-satellites-built-by-spacex-send-signals-in-the-wrong-direction\/\" target=\"_blank\" rel=\"noopener nofollow\" title=\"to the technology outlet Ars Technica\">to the technology outlet Ars Technica<\/a>.<\/p>\n\n\n<figure class=\"wp-block-embed is-type-rich is-provider-twitter wp-block-embed-twitter\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\"><p lang=\"en\" dir=\"ltr\">US spy satellites built by SpaceX send signals in the \u201cwrong direction\u201d <a href=\"https:\/\/t.co\/zW8JI4ieLR\">https:\/\/t.co\/zW8JI4ieLR<\/a><\/p>&mdash; Ars Technica (@arstechnica) <a href=\"https:\/\/twitter.com\/arstechnica\/status\/1989304430148419998?ref_src=twsrc%5Etfw\">November 14, 2025<\/a><\/blockquote><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script>\n<\/div><\/figure>\n\n\n<p class=\"wp-block-paragraph\">&#8220;If there is a constellation of very powerful signals emitting on the same frequencies, there is a possibility that they will interfere with the reception of the signals from the ground stations directed at the satellites in orbit,&#8221; he explains.<\/p>\n\n\n<p class=\"wp-block-paragraph\">Tilley had already <a href=\"https:\/\/arstechnica.com\/science\/2018\/01\/amateur-search-for-dead-spy-satellite-turns-up-undead-nasa-mission\/\" target=\"_blank\" rel=\"noopener nofollow\" title=\"\">made headlines in 2018<\/a> when he located a satellite that NASA had lost contact with in 2005.
