MeshSat

MeshSat is an open-source (GPLv3) routing layer that keeps people connected when the network is not. It bridges networks which cannot reach each other, so a message can enter on one bearer and leave on another: LoRa mesh (Meshtastic), Iridium satellite, SMS, APRS, ZigBee, BLE and plain TCP. It is a bridge between systems, not a replacement for any of them, and it is not an emergency service.

MeshSat is a prototype in active development and its reliability is not yet proven. A six-month field programme supported by SIDN fonds starts in November 2026. Videos here show real hardware and real tests, including the failures.
