Abstract:	In this paper the importance of timing monitoring and control systems for satellite navigation systems is explained and the current design and performance is detailed. Based on this, the composite clock concept for clock generation is introduced and the improved performance is analyzed. In order to reflect constraints introduced by the fact that the timing monitoring and control system needs to be based on a satellite like reduced computing power a new approach is developed and analyzed with reduced complexity. The paper will provide some details about the current state of the art of timing monitoring and control systems and performance improvements with a composite clock approach adapted to the constraints of space flight requirements.
