callbag-adsb

👜 callbag source for decoding, parsing, and streaming ads-b packets

Decodes and parses ads-b packets received from a software defined radio such as the repurposed digital tv usb stick known as rtl-sdr.

Usage

import adsbSource from 'callbag-adsb'
import observe from 'callbag-observe'

const messages = adsbSource()

observe(console.log)(messages)

Options

const messages = adsbSource(socketOptions?: SocketConnectOpts, reconnectionOptions?: Options)

socketOptions: see net.Socket SocketConnectOpts

Defaults to dump1090 port and host so you may not need to set it.

{
  port: 30002,
  host: 'localhost'
}

interface Options {
  connectionListener?: () => void | undefined   // Default: undefined
  reconnectOnEnd?: boolean,                     // Default: true
  retries?: number                              // Default: -1 always attempt reconnection
}

Config

If you already have dump1090 software running it will connect on localhost:30002. Otherwise, set env vars to change the port and host as required.

websocket_port=<your port>
websocket_host=<your host>

Alternatively, hard code your connection options:

const messages = adsbSource({ port: 30002, host: 'localhost' }, { retries: 90 })
