A mesh network for the skies.

MeshSky is an open protocol that links community feeders, AirBridge relays, and ControlTower nodes into a planetary mesh — democratizing aviation telemetry and MLAT for everyone.

  • 10k+ Feeders worldwide
  • <200ms Mesh propagation
  • 100% Open protocol

What MeshSky Is

A planetary mesh for aviation telemetry.

MeshSky stitches together independently-operated radio receivers — feeders — into a single, low-latency network. Aircraft signals captured anywhere on Earth become instantly available everywhere, without a central gatekeeper.

Open by default

An open protocol, open data, and open governance. Anyone can run a node, contribute, fork, or extend the spec.

Owned by operators

No single company owns the mesh. Feeders earn reputation; the network self-organizes through cryptographic peering.

Built for the edge

Runs on a Raspberry Pi, a router, or a hyperscale gateway. The protocol is bandwidth-aware and gracefully degrades.

Architecture

Three layers. One mesh.

MeshSky is composed of three cooperating tiers — feeders at the edge, AirBridge in the middle, and ControlTower at the apex — bound together by a gossip protocol with cryptographic provenance.

Designed to be unstoppable.

The mesh has no single point of failure. Feeders peer with multiple AirBridge relays; AirBridges gossip with each other; ControlTower nodes reach consensus on positions, identity, and reputation.

  • Cryptographic provenance — every observation is signed.
  • Reputation scoring — sybil-resistant by design.
  • Pluggable transports — TCP, QUIC, LoRa, mesh-radio.
  • Geographic sharding — bandwidth scales linearly with the network.

Feeders

A receiver near you, by you.

A feeder is anything that listens to the sky and signs what it hears. Run one on a $35 SDR and a Raspberry Pi, or scale to a roof-top antenna farm.

Run on anything

Official images for Raspberry Pi, x86 Linux, OpenWrt, and Docker. One-line install, automatic updates, signed releases.

Feeder docs

Earn reputation

Every signed observation increases your feeder’s standing. High-reputation feeders gain priority routing and (in time) protocol-level rewards.

How rewards work

Bandwidth-aware

Feeders negotiate compression and sample rates with their AirBridge peers. Run on satellite, LTE, or fiber — the mesh adapts.

Privacy-respecting

Operators choose what to share. Geo-fuzzing, opt-in identity, and signed audit trails are first-class protocol concerns.

AirBridge

The gossip layer of the sky.

AirBridge nodes form a gossiping mid-tier that fans out signed feeder observations across regions in under 200 milliseconds.

Sub-200ms fan-out

A QUIC-based gossip protocol propagates aircraft positions across continents faster than they can move.

Geographic sharding

Relays organize themselves into a Voronoi tessellation of the planet, so traffic stays local and latency stays low.

Self-healing

Lose a relay and the mesh re-routes in seconds. Lose a region and neighboring shards take over until you’re back.

ControlTower

The brain at the apex.

ControlTower nodes ingest the signed observation stream and produce the network’s authoritative outputs: deduplicated tracks, MLAT solutions, reputation scores, and a public API.

An indexer, a solver, a notary.

Anyone can run a ControlTower. They’re fully verifiable: every output is reproducible from the signed observation log. Multiple ControlTowers reach consensus through the same gossip layer, so the network stays trust-minimized even at the apex.

  • Track fusion — combine ADS-B, Mode-S, and MLAT into a single stream.
  • Reputation rollups — sybil-resistant scoring of feeders.
  • Public API — REST + streaming for downstream apps.
  • Verifiability — every result is a function of signed inputs.

MLAT

Multilateration, demonopolized.

MeshSky brings open MLAT to anyone — locating non-ADS-B aircraft using time-of-arrival differences across cooperating feeders, with zero proprietary servers.

Distributed solver

Solutions are computed in any ControlTower, verified independently, and re-broadcast through the mesh.

Sub-microsecond timing

GPS-disciplined feeders share precision time references. The protocol negotiates timing budgets per shard.

Coverage that compounds

Every new feeder strengthens MLAT for everyone in range — open data with positive externalities.

Decentralization

No kings. No gatekeepers.

MeshSky is a protocol, not a product. The reference implementations are MIT-licensed; the spec is governed in the open; the network has no admin button.

Open protocol

Versioned, semantically-stable, and forever public. Implement it in any language, on any platform.

Open governance

A foundation stewards the spec. RFCs are public. Anyone can propose changes; rough consensus and running code decide.

Open data

Network output is freely usable, with attribution. Operators can layer commercial services on top — the mesh stays free.

Pricing

The mesh is free. Pick a tier for tooling.

MeshSky the protocol is free, forever. The MeshSky Foundation offers paid tooling for operators who want managed dashboards, premium APIs, or enterprise SLAs.
