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 ​

Choose your setup for prerequisites and availability. The main components are:

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 Server-Sent Events for integration
  • Web dashboard for monitoring and management

MeshSat Hub ​

The control room for every kit, phone and node you run, on your own server or on ours at hub.meshsat.net. One place to watch every bridge and device: 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.

  • Hosted plans start with four devices and bridges free; self-hosted limits are yours to set
  • 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

To run your own Hub, start at Self-hosting.

MeshSat Android ​

The phone as the gateway. Paired with a MeshSat node, one Android phone sends and receives over the mesh, by satellite and by SMS, and keeps working with no internet. See Android.

  • Meshtastic over Bluetooth LE, through the node or any Meshtastic radio
  • Iridium SBD through the node's RockBLOCK 9603, with a queue that waits for the next pass
  • SMS through the phone's own SIM in the full APK edition; no SMS in the Google Play edition
  • Joins the Hub's fleet like a field kit, set up by QR code

iOS, Linux and hardware ​

iOS is the iPhone gateway, available from the App Store; source builds are also available. Linux packages the native app and Bridge for Linux phones. The node pairs with a phone for mesh and satellite; the field kits are the standalone hardware builds. Project sources maps all repositories.
