A particular strategy is devised to ensure capture into an uncontrolled relatively stable orbit at the Moon. Both uncertainty in the orbit determination process and in the control of the thrust vector are included in the navigation analysis. The orbit determination process is based on the definition of an optimal filtering technique that is able to meet accuracy requirements at an acceptable computational cost. Three sequential filtering techniques are analysed: an extended Kalman ","authors_text":"Massimiliano Vasile, Massimo Vetrisano, Willem van der Weg","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2012-07-14T15:17:40Z","title":"Navigating to the Moon Along Low-Energy Transfers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1207.3431","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:d5f8fb1de54acb8069f6063a900e642fd727687dbb8cef88492392b145aa2e43","target":"record","created_at":"2026-05-18T01:56:23Z","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":"e2447e634c9f4cabe1867b6ce5ca0485f0b6043ff4d0532218e84d7d5b427210","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.OC","submitted_at":"2012-07-14T15:17:40Z","title_canon_sha256":"1e01da51a781352006425ce58a0bac1154adc3be0532be904d5e733d5230450d"},"schema_version":"1.0","source":{"id":"1207.3431","kind":"arxiv","version":1}},"canonical_sha256":"6542c518898dae3c1bec7a7d880b6d45d4844aca318b03f6cfcead5f668fb951","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6542c518898dae3c1bec7a7d880b6d45d4844aca318b03f6cfcead5f668fb951","first_computed_at":"2026-05-18T01:56:23.660103Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:56:23.660103Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"U8rhlWuU+7MJmaBEkNFCeXQdZN9Y+IvC3Bpuyat53j6RX+i67iVf4yc2A+uByivFDG8ZFOoiIYg8ar/B3v+dCA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:56:23.660669Z","signed_message":"canonical_sha256_bytes"},"source_id":"1207.3431","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d5f8fb1de54acb8069f6063a900e642fd727687dbb8cef88492392b145aa2e43","sha256:3ff978989e3d1a61826474e44f6c07491bc6213afa42b591ae08c01befc0e392"],"state_sha256":"9cef4529e783d584fd2bdbc08fbed183c0a9409f89529ca170534f4bcafb3115"}
