What is it ?

TinyGS is an open network of Ground Stations distributed around the world to receive and operate LoRa satellites, weather probes and other flying objects, using cheap and versatile modules.

Why do it ?

I was thrilled when I saw this project go live, so I thought I should just build one myself, because why not? Building one is easy just get your hands on an sx126x or sx127x compatible board like the Lilygo ESP32 433Mhz and flash the software on (links below)

This project is based on ESP32 boards and currently it is compatible with sx126x and sx127x LoRa módules.

Currently these LoRa boards are supported:

• Heltec WiFi LoRa 32 V1 (433MHz & 863-928MHz versions)
• Heltec WiFi LoRa 32 V2 (433MHz & 863-928MHz versions)
• TTGO LoRa32 V1 (433MHz & 868-915MHz versions)
• TTGO LoRa32 V2 (433MHz & 868-915MHz versions)
• TTGO LoRa32 V2 (Manually swapped SX1267 to SX1278)
• T-BEAM + OLED (433MHz & 868-915MHz versions)
• T-BEAM V1.0 + OLED FOSSA 1W Ground Station (433MHz & 868-915MHz versions)
• ESP32 dev board + SX126X with crystal (Custom build, OLED optional)
• ESP32 dev board + SX126X with TCXO (Custom build, OLED optional)
• ESP32 dev board + SX127X (Custom build, OLED optional)

The way this is all networked together is quite interesting and hopefully it shall expand as time goes on and more interst is gained. Currently I’ve set up the receiver using a discone antenna , and it seems to be working well but due to the fact that im using a splitter it reduces the signal input X number of splits. To combat this, I am aiming to add a small Amplifier to combat the signal degradation at a later time.
