A target for use in a motion tracking system includes an optically transparent substrate with front and rear artwork. A robust landmark is comprised of portions of the front and rear artwork, and includes alternating spokes and interstitial spaces. The front and rear artwork also define orientation dependent radiation regions that occupy a portion of the interstitial spaces. The artwork also provides target identification markings and markings for providing in-plane rotation information. The surface area of the robust landmark maximized with respect to the total surface area of the target size.
