Large segmented space telescopes that can achieve 10^10 contrast are under consideration for both the Large Ultraviolet Optical Infra-Red (LUVOIR) and Habex mission studies. The key challenge for this type of architecture is how to achieve sufficient stability to support this level of contrast. This paper will survey a few emerging sensing and control architectures and associated technologies that can potentially achieve the required stability. It will also provide a summary of the sensing and control portion of the LUVOIR segmented telescope architecture that has emerged from a recent design study and will provide a first look at the control methods that are being employed.
