Missile: Position Covariance in Axes: ICR(CBF)

Intrack Crosstrack Radial using the velocity as measured in the central body fixed frame. The Z axis is outward along the radial, the Y axis is in the direction of the cross product of the position and velocity measured in the central body fixed frame and X axis is in the direction of motion and constructed as Y x Z.
