go-adsb is a Go module that includes packages for working with ADS-B and Mode S aircraft transponder data.

The beast package is a low-level library for handling data in Mode S Beast format, as provided by common software such as dump1090. Decoder provides a consumer for an io.Reader such as net.Conn, which will then parse a Beast stream into individual frames. These frames are passed to a BinaryUnmarshaler via Decode. The provided Frame is a BinaryUnmarshaler that provides methods to extract the Beast data such as timestamp and signal level, as well as the enclosed Mode S or ADS-B data.

The adsb package is a library for decoding Mode S and ADS-B transponder messages. RawMessage is a low-level wrapper that provides access to arbitrary bit sequences and named message fields. Message is a higher-level abstraction that provides functions to retrieve decoded values such as altitude and callsign from the encoded data.

Both Message and RawMessage designed to accept a beast.Frame to provide a complete solution for decoding usable values from an incoming data stream.

The adsbtype package provides constants for Mode S and ADS-B data fields that have fixed values. Converting the value to a provided data type allows the text description of the value to be returned via the %s operator in Printf-style operations.
