Global Navigation Satellites System (GNSS) receiver provides absolute localization for it. GNSS solution can provide satisfactory positioning in open or sub-urban areas, however, its performance suffered in super-urbanized area due to the phenomenon which are well-known as multipath effects and NLOS receptions. The effects dominate GNSS positioning performance in the area. The recent proposed 3D map aided (3DMA) GNSS can mitigate most of the multipath effects and NLOS receptions caused by buildings based on 3D c","authors_text":"Guohao Zhang, Li-Ta Hsu, Weisong Wen","cross_cats":["eess.SP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.RO","submitted_at":"2018-04-29T12:23:11Z","title":"Exclusion of GNSS NLOS Receptions Caused by Dynamic Objects in Heavy Traffic Urban Scenarios Using Real-Time 3D Point Cloud: An Approach without 3D Maps"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1804.10917","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":"sha256:84ee84ab0645eace73483806b3e18c67932cb49c2a283081e25ca63d5ba63423","target":"record","created_at":"2026-05-18T00:17:15Z","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":"7a097d2b860ab19d69830aea6ff18154847b68e1daac86c51d1be943b3e398fb","cross_cats_sorted":["eess.SP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.RO","submitted_at":"2018-04-29T12:23:11Z","title_canon_sha256":"059c81874abaa0fc266644b337f523cf7b0975d0e8d250a2198ee6ab69b284ff"},"schema_version":"1.0","source":{"id":"1804.10917","kind":"arxiv","version":1}},"canonical_sha256":"d24f3b515925832fa1c73cdaa31cf5644b4ff7b0836c8729f55880704bbc2039","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d24f3b515925832fa1c73cdaa31cf5644b4ff7b0836c8729f55880704bbc2039","first_computed_at":"2026-05-18T00:17:15.184354Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:17:15.184354Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Mxh8Bs573hK3o7j6c9nKoWGncQ8artIauThTudMgzL68tzCMSljSW/EAsQqPtMUFtLxtdROnhXf+FdpngZt4Dg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:17:15.184862Z","signed_message":"canonical_sha256_bytes"},"source_id":"1804.10917","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:84ee84ab0645eace73483806b3e18c67932cb49c2a283081e25ca63d5ba63423","sha256:30626736aed4be6d97d9d9f98bc6afb4b597f02904ca4048ed2e92e5d05904bd"],"state_sha256":"658667d312b6bb6326f0c87c391073b92150c15f2c42affade2be63709203eec"}
