Automatic Radiosonde Receiver Utilities

This fork of rs1279's RS codebase provides a set of utilities ('auto_rx') to allow automatic reception and uploading of Radiosonde positions to multiple services, including:

• The Habitat High-Altitude Balloon Tracker
• APRS-IS (for display on sites such as aprs.fi
• OziPlotter, for mobile radiosonde chasing.

Currently we support the following radiosonde types:

• Vaisala RS92SGP
• Vaisala RS41SGP

Support for other radiosondes may be added as required (send us sondes to test with!)

This software performs the following steps:

1. Use rtl_power to scan across a user-defined frequency range, and detect peaks in the spectrum.
2. For each detected peak frequency, run the rs_detect utility, which determines if a radiosonde signal is present, and what type it is.
3. If a radiosonde signal is found, start demodulating it, and upload data to various internet services.
4. If no peaks are found, or if no packets are heard from the radiosonde in a given amount of time (2 minutes by default), go back to step 1.

Refer to the wiki for installation and setup instructions.

Please note this software is under constant development. Please update (git pull) regularly!
