ADSB

Automatic Dependent Surveillance Broadcast is a cooperative surveillance technology in which an aircraft determines its position via satellite navigation and periodically broadcasts it. This gem decodes automatic dependent surveillance broadcasts.

Add this line to your application's Gemfile:

gem 'ruby-adsb', require: 'adsb'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ruby-adsb

Create a new message:

message = ADSB::Message.new('8D4840D6202CC371C32CE0576098')

Get the address of the sender:

address = message.address

Get the type of message:

type = message.type

The type of message is either :identification, :position, or :velocity.

Get the reported identification:

identification = message.identification

Create a new compact position report from a message of even parity and a message of odd parity:

even = ADSB::Message.new('8D40621D58C382D690C8AC2863A7')
odd = ADSB::Message.new('8D40621D58C386435CC412692AD6')
report = ADSB::CPR::Report.new(even, odd)

Get the reported altitude:

altitude = report.altitude

Get the reported latitude:

latitude = report.latitude

Get the reported longitude:

longitude = report.longitude

Get the reported heading:

heading = message.heading

Get the reported velocity:

velocity = message.velocity
