Open Satellite LoRaWAN at Scale
summary
Ordinary LoRaWAN sensors are shown reaching LEO satellites (~500 km, ~90‑min orbits) using store‑and‑forward satellite receivers and downlink ground stations tied into The Things Network. The implementation uses open‑source modem and network‑server integration, SX126x‑compatible modems and simple patch/circular antennas; live demos proved messages were received and returned, though intermittent passes (few per day per satellite) impose capacity and latency limits that a multi‑satellite constellation can mitigate.
