Mesh-Derived Coordinates

GNSS is the load-bearing assumption of modern autonomy, and it fails predictably: jammed in defense theaters, multipath-degraded in urban canyons, denied indoors, deliberately spoofed in critical infrastructure attacks. This article introduces mesh-derived coordinates: cooperative localization across fifteen-plus ranging modalities with credentialed range observations, anchor-less relative-frame bootstrap, and on-demand reference-node densification.

Mesh-derived coordinates produce positions through mutual ranging across fifteen-plus modalities — UWB time-of-flight, lidar reflection, radar, optical fiducial range, RFID proximity, NFC adjacency, acoustic echo, BLE RSSI, magnetic dipole, GNSS pseudorange, inertial integration, visual SLAM correspondence, and others.

Mesh-derived coordinates emerge from cooperative localization where each unit contributes range observations to others. The coordinate frame is a structural product of the cooperation rather than a broadcast from a central authority.

Mesh units deployed to a new operating region produce a relative coordinate frame from mutual ranging before any absolute reference is available. Operations begin in relative frame; absolute binding follows as anchor observations accumulate.

Each range observation entering the multilateration solver is governance-credentialed: the contributing unit signs the observation, the modality and uncertainty are declared, and the observation is recorded with full lineage for downstream audit.

The multilateration solver produces position estimates bound to the lineage of contributing observations. The position is not an opaque output; it is a structured claim with traversable provenance back to each contributing range observation.

The architecture rejects observations carrying invalid credentials, anomalous timing patterns, or modality outputs inconsistent with cross-modality cross-checks. Spoofed observations fail the admissibility evaluation rather than entering the position solution.

Operating regions gain positioning quality through reference node densification — additional anchor units with surveyed or GNSS-derived position bind the cooperative solution to absolute frame at progressively higher confidence as density increases.

Forward-deployed operations gain rapid mesh establishment through airdroppable reference nodes that self-survey on landing, acquire GNSS or external reference binding, and contribute as anchors to the cooperative solution within minutes of deployment.

Adjacent mesh regions maintain their own coordinate solutions and federate at boundaries through credentialed cross-region observations. The federated frame supports operations spanning region boundaries without forcing a single global solution.

Operations crossing jurisdictional boundaries (national borders, regulatory regions, operating-authority territories) require coordinate alignment that respects each jurisdiction's positioning authority. Cross-jurisdictional alignment composes the regional authorities through declared agreements.

Defense operations under GNSS denial gain structurally-supported positioning through multi-modality cooperative ranging. The architectural primitive provides positioning that survives the GNSS-denial that contested-environment doctrine assumes.

Subterranean operations (mining, tunneling, search-and-rescue, defense underground) face structural GNSS denial. Multi-modality cooperative ranging provides positioning that subterranean operations have historically lacked.

Urban canyon environments produce structural GNSS degradation. Multi-modality cooperative ranging provides positioning resilience that urban operations require for emerging autonomous-mobility deployment.

Maritime Autonomous Surface Ships (MASS) operations under IMO frameworks require positioning resilience and audit-grade positioning lineage beyond conventional GPS. Mesh-derived coordinates provide structural support for autonomous-shipping deployment.

Coordinated GPS jamming and spoofing operations targeting positioning infrastructure produce cascading effects across operational domains. Mesh-derived coordinates produce structural defense through cooperative multi-modality ranging that single-modality jamming cannot defeat.

Drone airspace integration (FAA UTM in U.S., EASA U-space in Europe, similar emerging frameworks) requires positioning resilience and credentialed positioning lineage that single-modality GPS cannot match. Mesh-derived coordinates support drone-airspace integration structurally.

Hospital operations integrate patient-tracking, asset-tracking, infection-control monitoring, and staff-coordination into Real-Time Location Systems (RTLS). Mesh-derived coordinates with credentialed multi-modality ranging support hospital-grade positioning beyond current vendor-specific RTLS deployments.

Emerging consumer applications (precise indoor navigation, AR/VR positioning, mass-market autonomy) require sub-meter positioning that smartphone-class GPS cannot deliver. Cooperative multi-modality ranging integrated into smartphone-class hardware supports mass-market sub-meter positioning.
