https://levelzero.fr/ 2026-07-13T20:51:29+02:00 weekly 1.0 https://levelzero.fr/brand/og/og-default.png Level Zero - sensor data, standardized. Level Zero is a sovereign, TRL-4 ground-segment provenance layer. It conditions representative multidomain inputs - satellite downlink frames, EO/SAR scene metadata, live track state and operator reports - into one canonical product (lz.canonical.v1), Ed25519-signs it, hash-chains an append-only chain of custody, and exposes an independent public verifier pinned to a published trust anchor (forged keys are rejected). It produces bounded corroboration candidates within an explicit space-and-time gate and publishes a JSON Schema plus an OGC SensorThings alignment crosswalk; outputs are canonical JSON and GeoJSON over a REST API. It does not demodulate raw RF or emit STAC/COG/RINEX/SensorML, and it ships no SDK - those are roadmap. https://levelzero.fr/brand/og/og-square.png Level Zero square social card https://levelzero.fr/sitemap.html 2026-07-13T20:51:29+02:00 monthly 0.5 https://levelzero.fr/company/about/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/company/contact/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/company/customers/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/developers/rest-api/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/developers/status/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/developers/typescript-sdk/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/developers/webhooks/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/legal/aup/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/legal/cookies/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/legal/dpa/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/legal/notice/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/legal/privacy/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/legal/terms/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/platform/imagery/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/platform/mission-ops/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/platform/signal-gnss/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/platform/stac-catalog/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/trust/gdpr/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/trust/iso-27001/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/trust/nist-csf/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/trust/sbom-slsa/ 2026-07-13T20:51:29+02:00 monthly 0.7 https://levelzero.fr/trust/soc2/ 2026-07-13T20:51:29+02:00 monthly 0.7
