This library contains software used to encode and decode telemetry used by the Project Horus High-Altitude Balloon (HAB) project (amongst other users). This software was originally developed as part of the [codec2](https://github.com/drowe67/codec2) project, but as of 2020 has been broken out into this separate project, to keep codec2 targeted at low-level voice-codec and modem development.
This library includes the following:
* The 'HorusBinary' demodulator, a high performance 4FSK modem used for low-rate positional telemetry from HABs. More information on this modem can be found here: https://github.com/projecthorus/horusbinary (This repository will eventually be re-worked to use this library)
* The 'Wenet' demodulator, used to downlink imagery from HAB payloads.
Here are some links to projects and blog posts that use this code:
