Attitude representations and coordinate transformations are fundamental to almost every GNC, robotics, and 3D simulation system — yet the different conventions and standards used across industries are a persistent source of confusion. This course cuts through that confusion with a rigorous but practical treatment of the subject.

You will come away with a thorough understanding of all three major rotation representations, how to convert between them, and how to implement them in working code.

What You Will Learn

• How to represent attitude using Direction Cosine Matrices (DCMs), Euler Angles, and Quaternions
• How to convert between all three representations
• How to calculate transforms between different reference frames
• The advantages, disadvantages, and practical trade-offs of each approach
• The conventions and standards commonly used in industry — and where they differ
• How to implement a complete C++ Attitude Math Library from scratch
• How to use Python to analyse and validate attitude-related problems

Who This Course Is For

• Aerospace and GNC engineers who need a rigorous reference for rotation mathematics
• Engineers and scientists building simulations or flight software
• Programmers implementing attitude systems in game engines (Unity, Unreal) or robotics frameworks
• University students studying GNC, robotics, or computer graphics
• Anyone who wants to move from understanding the theory to writing working code

Prerequisites

A working knowledge of linear algebra (matrix multiplication, transposes, determinants) and basic trigonometry is assumed. No prior knowledge of rotations or attitude representations is required.
