summary

Demonstrates broadcasting LoRa messages from a low‑Earth orbit satellite (XLiI) that are received by simple, commodity ground setups including Raspberry Pi + SDR, Arduino microcontroller boards with SD cards, and small antennas. Experiments show 2–3 minute satellite passes with kilohertz-scale Doppler shifts over maritime channels using wideband LoRa bursts; reception statistics (message counts and SNR varying with elevation) confirm successful receipt of real packets.
