We show that this relative-geometry channel has a structural blind spot: a common, slowly varying translation (a rigid-covert shift, RigidShift) preserves all pairwise distances and is therefore unobservable to any relative-only detector (a gauge-freedom argument). We validate this blindness on distance-verification and semidefinite-feasibility baselines, while explicitly distinguishing it from onboard inertial/GNSS monitors that can raise a bare alarm but cannot recover the swarm's true p","authors_text":"Joon Soo Yoo, Minseok Park","cross_cats":["cs.RO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2026-08-07T07:15:55Z","title":"Rigid-Covert GNSS Spoofing of UAV Swarms: A Structural Blind Spot, Its Detection Limit, and Absolute-Anchor Defenses"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2608.06885","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:d23d04606be5720e0f58dd377a9c95c0b4722a688c33d2765287b19a37766755","target":"record","created_at":"2026-08-10T01:12:24Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"31a8ff6b3452beb193120cc355ed2cac40af9f306d81dcd4ee37c0a883018721","cross_cats_sorted":["cs.RO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CR","submitted_at":"2026-08-07T07:15:55Z","title_canon_sha256":"5b0444f1cf300b9d45545db7bb6920d205f0ddd5a1603e48d6a0723f8f0ced64"},"schema_version":"1.0","source":{"id":"2608.06885","kind":"arxiv","version":1}},"canonical_sha256":"5874d89328720c639a7f6a9a58a9d0af9fb1d9629e4bd0ecbe5016a4ee1977d7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5874d89328720c639a7f6a9a58a9d0af9fb1d9629e4bd0ecbe5016a4ee1977d7","first_computed_at":"2026-08-10T01:12:24.775941Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-08-10T01:12:24.775941Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"JX+zQs8aGLo2nlV7I3istf7yiS5B6rlqnElbR2q99BM/U66IsP4Mab1U/nc9e9AhsIl0ggJRpT7YE+eFhjFiDg==","signature_status":"signed_v1","signed_at":"2026-08-10T01:12:24.778560Z","signed_message":"canonical_sha256_bytes"},"source_id":"2608.06885","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d23d04606be5720e0f58dd377a9c95c0b4722a688c33d2765287b19a37766755","sha256:62f01154fd1e755c6498dc0b2411ff0b45a8ebc62c013db84e014a91c15c5c7b","sha256:9074efcf6b9e38e70556fd9bb10f3ab9a70b8a1906fcd27996564322a94fed20"],"state_sha256":"245b839562f090091aed1d41446bc61af7a32e10c74124406cd2f0a8e699faaf"}
