Coordinate systems are an important part of aerospace systems. Use the coordinate system blocks to standardize units across your model, transform spatial representations and coordinate systems, describe the behavior of three- and six-degrees-of-motion bodies, and perform common aerospace math operations.

For example, axes transformation blocks support transformations such as those between:

• Direction cosine matrices and quaternions

• Rotation angles and quaternions

• Earth-centered inertial (ECI) coordinates and azimuth or geodetic latitude, longitude, altitude (LLA) coordinates

• Flat Earth positions from geodetic latitude, longitude, and altitude
