The environment combines the flexibility, determinism, and observability of software-only simulation with the fidelity and depth normally attained only by real-time hardware-in-the-loop testing. Ultimately, this work enables an engineering process in which flight software is continuously improved and delivered in its final, flight-ready form, and which reduces the cost of design changes and software revisions wit","authors_text":"Simone D'Amico, Toby Bell","cross_cats":["cs.MA","cs.RO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SE","submitted_at":"2025-05-18T17:32:40Z","title":"Event-Driven Simulation for Rapid Iterative Development of Distributed Space Flight Software"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2505.12502","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":"sha256:7b92db177c29d98ca9bd95966ed7191ea55fc53f30549bedf8504c01009ad73d","target":"record","created_at":"2026-07-05T11:05:05Z","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":"89232baa797b4fc4af994211b5fbda49b81c9e68109af571bf05daad52146bcf","cross_cats_sorted":["cs.MA","cs.RO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SE","submitted_at":"2025-05-18T17:32:40Z","title_canon_sha256":"53f920ee4e8923500c2916efcc93a491e760fbda017de6154976ecc6defb2df6"},"schema_version":"1.0","source":{"id":"2505.12502","kind":"arxiv","version":1}},"canonical_sha256":"4703e89bb291ce43655d2ab38ddc8558619094ee5d60b4bcc6e85514a8d56871","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4703e89bb291ce43655d2ab38ddc8558619094ee5d60b4bcc6e85514a8d56871","first_computed_at":"2026-07-05T11:05:05.354459Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:05:05.354459Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BYzBXzNKcielgi9RGmfSGueMG4FHuh5LPWZ4UgcGIdKmNtUDIrJcnH+qlUvIop0bk+xklph/URZGfkdxRG4eCA==","signature_status":"signed_v1","signed_at":"2026-07-05T11:05:05.354961Z","signed_message":"canonical_sha256_bytes"},"source_id":"2505.12502","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7b92db177c29d98ca9bd95966ed7191ea55fc53f30549bedf8504c01009ad73d","sha256:45897fd4d00ecd6468c4b04b6e1a3dd55d6e21427361823f1d12948b0fd0ec26"],"state_sha256":"b6ccf0449fbaebc3d52ffed3a4541c1000855b0f8a1daf01fb6ec8f4dfec487a"}
