%description
Tools to work with signals and files from GOES satellites.

* goesrecv: Demodulate and decode signal into packet stream.
* goeslrit: Assemble LRIT files from packet stream.
* goesproc: Process LRIT files into plain files and images.

I started writing this to learn about things involved in the GOES communication
pipeline and in the process learn more about space communication standards.
Everything is written in C++ to strike a balance between usability (no need for
yet another hash table in C) and performance.

%description -n goesrecv
You can use goesrecv with an RTL-SDR (make sure you have one with the R820T
tuner chip), or an Airspy (confirmed to work with the Mini). The raw signal is
then processed by the demodulator and turned into a stream of 1s and 0s. This
is then passed to the decoder where the bitstream is synchronized and error
correction is applied. Every valid packet is then forwarded to downstream tools
(e.g. goeslrit or goesproc).
