TBTracker-ESP32

A Plug and Play High Altitude Balloon tracker for ESP32. Supports LoRa, LoRa-APRS, RTTY, Horus V1 4FSK, Horus V2 4FSK.

TBTracker-ESP32 is an Arduino sketch for a tracker for high altitude weather or scientific balloons. It supports sending telemetry data in mulitple formats:

• RTTY
• LoRa
• LoRa-APRS
• Horus 4FSK V1
• Horus 4FSK V2

You can select multiple modes or just a single mode.

It is designed to send telemetry data in the correct format for https://amateur.sondehub.org.

The code is written in the Arduino IDE for ESP32 with a GPS module and a LoRa module like the sx1278 or sx1276 or Hope RFM9x.

Library

You will need to install two extra Arduino library from the librairy manager:

• Radiolib
• TinyGPS++

Hardware

The minimal hardware configuration you need is:

• ESP32 or ESP32S2 board
• GPS module (recommended Ublox Neo or ATGM336H)
• Lora module (sx1278 or sx1276 or Hope RFM9x module)

Horusbinary_radiolib

The radio related basecode for this sketch was taken from the horusbinary_radiolib project. See: https://github.com/projecthorus/horusbinary_radiolib

Installation

Connect your LoRa and GPS modules to your ESP board and change the values in the settings.h file.See the comments in the settings.h file. Compile in the Arduino IDE and upload to your board.
