UK military jamming other nations' satellites to defend itself, BBC told
UK plans to use ground-based systems to jam foreign satellites seen as threats to its security, highlighting how vulnerable modern economies are to space-based infrastructure for GPS, communications and finance. Commenters debate the rationale and risks of such “soft kill” tactics, from their impact on treaty verification and escalation dynamics to the fragility of cashless banking and undersea cable dependence. The conversation also explores technical angles, including satellite laser links, GPS alternatives, and how future conflicts might target space assets and global connectivity.
Satellite jamming as strategy
- Many see UK satellite jamming as predictable in great‑power competition and hybrid conflict, especially given Russian GPS disruption and subsea cable threats.
- Others question the strategic value, calling it costly, escalatory, or “military‑industrial” self‑interest, and note that reconnaissance satellites also support treaty verification.
- It’s unclear from the discussion exactly which satellites are being jammed or what counts as “targeting the UK” (e.g., imaging, tracking submarines, or just overflight).
GPS, timing, and “banking apps”
- The article’s focus on “banking apps” as a justification is widely mocked as odd or misleading.
- Some argue GPS is essential because its precise timing underpins financial networks and critical infrastructure; loss of GNSS would disrupt payments and settlement.
- Others counter that end‑user banking apps neither require GPS nor satellite internet, and that most consumer internet uses terrestrial networks.
- A side debate notes that UK finance is structurally exposed if undersea cables are cut and cloud‑hosted banking infrastructure can’t “phone home.”
Digital dependence and cashless risks
- Several commenters argue a heavily cashless society is fragile: service disruptions could cripple everyday transactions and livelihoods.
- Others respond that websites, ATMs, and cards depend on the same networks as apps, so apps are just the most visible example, not the root issue.
- There is unease about people being effectively locked out of banking if they lose their phone, or if mobile‑app‑only features become standard.
Privacy and surveillance via digital finance
- A long tangent claims many banking apps leak transaction data to third‑party analytics firms, enabling extensive profiling and potential intelligence use.
- Others insist this is orthogonal to the jamming / availability question, but the thread ties it to why some prefer cash.
Alternatives to satellites and GPS
- Discussion touches on backups: inertial navigation, terrain matching (e.g., TERCOM), star navigation, radio beacons, cell‑tower and Wi‑Fi triangulation, and satellite‑to‑satellite laser links.
- Some expect future conflicts to see GPS denial, undersea cable cuts, and attacks on large constellations like Starlink, raising concerns about debris and potential Kessler syndrome.
