Understanding Spatial AI & Autonomous Vehicle Reference Frames

In autonomous driving, SLAM (Simultaneous Localization and Mapping), and UAV navigation, positions are transformed across three fundamental coordinate spaces:

Geodetic WGS84 $(phi, lambda, h)$: Global GNSS reference coordinates using latitude, longitude, and ellipsoidal height.
ECEF $(X, Y, Z)$: Cartesian coordinates centered at Earth's center of mass, used for satellite orbit calculations and global sensor fusion.
Local Tangent ENU / NED: East-North-Up or North-East-Down local Cartesian frame attached to the vehicle or origin station for real-time trajectory tracking.
