IRIG 106 Synthetic Data Generation Tools

These software tools are used to generate IRIG 106 Chapter 10 flight test data files from synthesized flight and sensor data. Generating synthetic Ch 10 data is a Multi-Step process. COTS, GOTS, and Custom Applications are used. This repository contains the custom software tools which, when used with the described GOTS and COTS sofware, will generate

Current Ch 10 Data Types Generated

  • Time
  • Video
  • Cockpit View
  • HUD View
  • Chase Plane View
  • 1553 Navigation Message
