Introduction
MeshSat is a unified message routing gateway that bridges mesh radios, satellite modems, cellular networks, and IP-based services into a single coherent system. Messages arrive on any transport and can be routed to any other transport based on configurable policies.
The MeshSat Family
MeshSat ships as three products, each targeting a different deployment scenario:
MeshSat Bridge
The standalone gateway. A single Go binary that runs on a Raspberry Pi (or any ARM64/x86 machine) and connects directly to hardware — serial ports, USB devices, and network interfaces. Bridge is fully self-contained with no cloud dependency.
- Runs on Raspberry Pi 4/5, ARM64 SBCs, or x86/amd64 servers
- Direct serial access to Meshtastic radios, Iridium modems, and more
- Local SQLite database for message history and configuration
- REST API and WebSocket for integration
- Web dashboard for monitoring and management
MeshSat Hub
The hosted fleet manager at hub.meshsat.net. One place to watch every bridge and device you run: live map, message history, routing between bearers, SOS escalation and an audit log. You bring your own satellite and SMS accounts, so your airtime stays yours.
- Free for four devices and bridges, paid plans above that
- Live map and message log across the whole fleet
- SOS escalation chains and a dead man's switch
- Your own Cloudloop, Rock7 and Twilio credentials, encrypted per account
- Accounts and plans covers signing up and what each plan allows
You can also run your own Hub; see Authentication and Hub configuration.
MeshSat Android
The mobile gateway. An Android app that turns a phone into a portable MeshSat node using BLE for Meshtastic, SPP for Iridium, and native SMS for cellular. See Android.
- BLE mesh networking with Meshtastic devices
- SPP serial for Iridium satellite modems
- Native SMS gateway
- ONNX Runtime for on-device ML inference
- Jetpack Compose UI
