    Variable X_AXIS_NORTHConst

    X_AXIS_NORTH: Matrix = ...

    Axes of the coordinate frame E (Earth-Centred, Earth-Fixed, ECEF) when the x-axis points to the North Pole.

    The x-axis points to the North Pole, y-axis points towards longitude +90deg (east) and latitude = 0. This choice of axis directions ensures that at zero latitude and longitude, N (North-East-Down) has the same orientation as E. If roll/pitch/yaw are zero, also B (Body, forward, starboard, down) has this orientation. In this manner, the axes of E is chosen to correspond with the axes of N and B.
