Preface

Getting Started

Welcome to L-3 Telemetry-West's Web-based Telemetry Tutorial. This basic course covers the entire telemetry process — everything from taking measurements to displaying and archiving results to analyzing data for mission-critical applications. While this tutorial is structured to flow sequentially, we encourage you to jump around to your areas of interest.

A Word on Telemetry Definitions

Telemetry sure would have come in handy for the Wright brothers at Kitty Hawk, North Carolina back in 1903. But it wasn’t pioneered until some years later by engineers from different disciplines and industries. As fate would have it, each deployed their own unique set of telemetry nomenclature. Even today, definitions used in airborne, ground, space, flight test, or industrial applications may differ.

L-3 Telemetry-West’s heritage is in aircraft ground systems, so the definitions used in this tutorial will be ground oriented. Click on the Glossary for a comprehensive summary of telemetry definitions. You can also jump to the Additional Sources section to get even more information on Telemetry.
