Mechanism
Each mesh-derived coordinate system carries a coordinate-frame specifier as a first-class governed object. The specifier defines the frame type, origin, orientation, scale, and temporal association of the coordinate system, and the coordinate system itself is produced cooperatively by participating mesh agents through inter-agent ranging, anchor observation admission, and governance-credentialed frame definition. A coordinate value is meaningful only when paired with the system in which it is expressed, and the architecture does not assume a single global coordinate frame.
Federation is the mechanism that aligns two or more independent mesh-derived coordinate systems. The disclosed coordinate-frame federation mechanism aligns these systems while preserving the governance chain, so that a position determined in one cooperatively-localized graph can be expressed in another. The alignment is itself a governed operation: each federation event is recorded in the coordinate-lineage record alongside the range observations, localization events, frame definitions, uncertainty updates, ambiguity resolutions, and rejection events that produced the positions being aligned.
A cross-system observation, in which a position determined in one mesh-derived coordinate system is consumed in another, proceeds through the same admissibility evaluation that governs every coordinate determination. Range observations are authenticated through the governance-chain continuity identity and evaluated for admissibility through the composite admissibility evaluator, so an alignment built on inadmissible or adversarial range observations is not admitted. The adversarial-range rejection mechanism rejects spoofed, injected, or otherwise inadmissible range observations before they can contribute to a federated position, and each rejection is recorded in lineage.
Governance-chain preservation is the structural property that distinguishes the disclosed federation. Each federated position is reconstructable to its derivation chain: the range observations, anchor contributions, localization events, and federation events that produced it are recorded in the governance-chain lineage field, so that a consumer downstream of the federation can determine how a cross-system position was derived. The precision of a mesh-derived position is bounded by ranging-modality accuracy and reference-node density, and the precision-and-uncertainty propagator propagates ranging precision and ranging-covariance through the localization chain to produce per-position uncertainty estimates that carry through the federation.
Operating Parameters
The mesh-derived coordinate primitive admits a plurality of ranging modalities and a plurality of coordinate frame types integrated into a single coordinate graph. The coordinate-frame specifier records the frame type, origin, orientation, scale, and temporal association for each system, and federation aligns systems that may differ in any of these. The federation does not require that every system be aligned to every other; it aligns the systems that operationally need to interoperate, and unaligned systems continue to function independently.
The precision of mesh-derived coordinates is bounded by ranging-modality accuracy and reference-node density within ranging distance of consuming agents. Where precision falls below governance-policy-defined thresholds, the reference-node densification mechanism produces on-demand coordinate-precision improvement by integrating additional reference nodes into the existing coordinate system, after which the deployed nodes are integrated through cooperative localization. Densification is governance-policy-configurable per deployment, and the uncertainty introduced or reduced by densification propagates through the localization chain and into any federated position.
Uncertainty accumulates as positions are propagated and aligned. The precision-and-uncertainty propagator propagates ranging precision and ranging-covariance through the localization chain, producing per-position uncertainty estimates, and the ambiguity-resolution mechanism selects among multiple solutions when multilateration admits more than one. The architecture admits a transitive localization extender that produces agent positions through neighbor references when direct-anchor ranging is insufficient, and an anchor-less bootstrap mechanism that produces a relative-only coordinate frame when no anchor observations are available; a relative-only frame can itself participate in federation once it is aligned to another system.
Alternative Embodiments
In a first embodiment, federation aligns two independent mesh-derived coordinate systems that each grew from their own anchors. In a second embodiment, one system is the anchor-less relative-only frame produced by the bootstrap mechanism and the other carries admitted anchor positions, so that federation gives the relative-only frame a shared reference. In a third embodiment, a federated position is fused with an externally-sourced position through the composite admissibility evaluator, where the external source may be satellite navigation, inertial dead-reckoning, visual-inertial odometry, or any external source, treated as one more governed observation rather than as ground truth. Each embodiment preserves the governance chain and records its federation events in lineage.
Variant ranging inventories are admitted. The primitive admits a plurality of ranging modalities integrated into a single coordinate graph, and the coordinate-frame specifier admits a plurality of coordinate frame types, so federation may align systems built on different modality mixes and different frame types. Reference nodes contributing to a federated system may take any densification form, including pre-placed permanent nodes, deployable semi-permanent nodes, airdroppable expendable nodes, vehicle-deployable nodes, drone-positionable nodes, hand-placeable nodes, and mobile nodes on authority-credentialed platforms.
Composition
Coordinate-frame federation composes with the broader mesh-coordinate primitive, which itself composes with the governed mesh protocol through range-observation emission and ingestion, with the dispositional field through disposition-weighted range admission, and with the cross-domain coherence evaluator through multi-source range corroboration. A federated position is the output of this composed primitive: range observations are admitted under governance, localization produces positions, and federation aligns positions across independent systems, with each step recorded in lineage. Federation is therefore not a convenience layer that hides coordinate conversion; it is a governed operation evaluated under the same admissibility rules as every other coordinate determination.
Composition with the anchor observation admission interface pairs each cooperatively-localized system with the anchor position contributions admitted into it, and federation aligns systems whose anchor sets differ. Composition with the capability envelope supports coordinate-precision-bounded operation, so a consumer that requires a given precision can be governed against the per-position uncertainty that the propagator carries through the federation. Composition with the coordinate-lineage recorder records each federation event alongside the originating range observations, localization events, frame definitions, uncertainty updates, ambiguity resolutions, and rejection events, allowing reconstruction of how any cross-system position was derived.
The federation also composes with deployments spanning more than one operating context. The mesh-derived coordinate primitive operates without dependence on any specific external positioning infrastructure and does not assume a single global coordinate frame, so a deployment may maintain several independent mesh-derived coordinate systems and align them only where they need to interoperate. A new system enters the federation by being aligned to an existing one, and systems that do not need to interoperate are unaffected. The architecture therefore supports growth without forcing global re-coordination.
Prior-Art Distinction
Prior satellite-navigation systems operate on broadcast signals from centrally-operated constellations whose acquisition is required for positioning and whose denial precludes positioning, whereas the disclosed primitive produces coordinate bearings from cooperating mesh agents without dependence on central positioning authority, and can federate two such independently-grown systems. Prior differential-positioning and assisted-positioning systems operate on reference-station networks maintained by positioning-service operators, whereas the disclosed primitive self-organizes through mesh agents without dependence on a positioning-service operator. Prior positioning systems using static identifiers, such as satellite pseudo-random-noise codes, beacon broadcast addresses, and fixed-identifier access points, are vulnerable to identifier spoofing, whereas the disclosed primitive authenticates each range observation through the governance-chain continuity identity and rejects inadmissible ranges before they contribute to a federated position.
Prior modality-specific positioning systems are limited to a single ranging modality, whereas the disclosed primitive admits a plurality of ranging modalities integrated into a single coordinate graph. Prior positioning systems produce a single canonical position without consumer-specific differentiation and do not support governance-chain-preserving lineage for coordinate determinations, whereas the disclosed primitive produces authority-filtered emissions and deterministic reconstruction of each position's derivation chain. Critically, prior systems do not support coordinate-frame federation across independently-maintained systems, whereas the disclosed primitive produces governance-chain-preserving federation of two or more independent mesh-derived coordinate systems.
