This is the FlightAware 978MHz UAT decoder.
It is a reimplementation in C++, loosely based on the demodulator from https://github.com/mutability/dump978.
For prebuilt Raspbian packages, see https://flightaware.com/adsb/piaware/install
dump978-fa is the main binary. It talks to the SDR, demodulates UAT data, and provides the data in a variety of ways - either as raw messages or as json-formatted decoded messages, and either on a network port or to stdout.
skyaware978 connects to a running dump978-fa and writes json files suitable for use by the SkyAware web map.
Caution: The package build is memory-hungry. A 1GB Pi will fail to build the package. Please build on a machine with more memory, or add swap.

- Ensure SoapySDR and Boost are installed
- 'make'
You will want at least one SoapySDR driver installed. For rtlsdr, try
$ sudo apt-get install soapysdr-module-rtlsdr
For a package install, see /etc/default/dump978-fa and
/etc/default/skyaware978.
The main options are:
--sdrspecifies the SDR to use, in the format expected by SoapySDR. For a rtlsdr, try--sdr driver=rtlsdr. To select a particular rtlsdr dongle by serial number, try--sdr driver=rtlsdr,serial=01234567--sdr-gainsets the SDR gain (default: max)--raw-portlistens on the given TCP port and provides raw messages--json-portlistens on the given TCP port and provides decoded messages in json format
Pass --help for a full list of options.
