igc

FAI Compliant IGC file parser.

Implemented version: 2020-11-25

• IGC File parsing:

  • A record - Flight Recorder Identification
  • H record - Headers
  • I record - Additions to the B record
  • J record - Additions to the K record
  • C record - Task
  • G record - Security
  • B record - Fixes
  • E record - Events
  • F record - Satellite Constellations
  • K record - Data needed less frequently than fixes
  • L record - Comments
  • D record - Differential GNSS

• IGC File writing

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     igc:
       github: albertorestifo/igc.cr

2. Run shards install

Usage

require "igc"

parsed = File.open("my_flight.igc") do |file|
  IGC.parse(file)
end

pp parsed.fixes # => prints out all the fixes in the file

The result of calling IGC.parse is an instance of IGC::File, with properties:

• flight_recorder_id: Identifier of the device that recorded the IGC data
• headers: Metadata contained in the file
• task: Task definition (if present)
• fixes: Array of fixes recorded in the file
• datapoints: Extra data recorded at regular intervals
