	PETRA III, a 6 GeV synchrotron light source will have a horizontal beam emittance of 1nm·rad and a 1% emittance ratio. As the vertical beam sizes are ~5–10 micron in the low gap undulator sections the beam position stability requirement in the vertical plane is between 0.5 and 1 micron whereas the stability requirement in the horizontal plane is more relaxed. In order to obtain and maintain the small emittances imposes tight tolerances on spurious dispersion and orbit quality and stability. A fast orbit feedback is foreseen to achieve the required orbit stability. The conceptual layout and the basic design parameters of this system will be described in this presentation
