Automatic Radiosonde RX Station Extensions

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.

By running auto_rx continuously, not just at known radiosonde launch times, you may see other radiosonde launches (military or otherwise) that would otherwise go un-noticed.
