Trajectory axes coordinate types.

Member	Value	Description
eCrdnTrajectoryAxesICR	0	Intrack Crosstrack Radial Axes. The Z axis is outward along the position vector (radial); the Y axis is along the cross product of the position and velocity (crosstrack); the X axis is in the direction of motion and constructed as Y x Z (intrack).
eCrdnTrajectoryAxesVNC	1	Velocity - Normal - Co-normal Axes. The X axis is along the velocity vector; the Y axis is along the cross product of the position and velocity (normal); the Z axis is constructed as X x Y (co-normal).
eCrdnTrajectoryAxesRIC	2	Radial Intrack Crosstrack Axes. The X axis is outward along the position vector (radial); the Z axis is along the cross product of the position and velocity (crosstrack); the Y axis is in the direction of motion and is constructed as Z x X (intrack).
eCrdnTrajectoryAxesLVLH	3	Local Vertical, Local Horizontal Axes. The X axis is along the position vector (local vertical); the Z axis is along the cross product of the position and velocity; the Y axis is in the direction of motion and constructed as Z x X (local horizontal).
eCrdnTrajectoryAxesVVLH	4	Vehicle Velocity, Local Horizontal Axes. The Z axis is along the negative position vector; the Y axis is along the negative cross product of the position and velocity (local horizontal); the X axis is constructed as Z x Y (toward velocity).
eCrdnTrajectoryAxesBBR	5	Body-to-body Rotating Axes. The X axis is along the negative position vector; the Z axis is along the cross product of the position and velocity; the Y axis is constructed as Z x X.
