3 x 3 Rotation Matrices in Air Traffic Control (UMAP)

Author: Helen Wang


This module shows how orthogonal matrices are used to translate into local coordinates the airplane coordinate sent by radar sites to air traffic control centers in a system designed for West Germany by Raytheon Company in 1978. Students compute specific 3 x 3 matrices and use them in real-world coordinate transformation problems.
