	A new steering software for cycle-to-cycle closed orbit as well as trajectory control is currently under development for FAIR's planned control system. It has been successfully tested with beam at the SIS18 in 2016. COAT (i.e., Controlling Orbits And Trajectories) has been realized as a distributed, Java-based application. It consists of a background daemon process that handles the actual beam-based feedback logic, and independent clients that provide visualization and various user-interaction capabilities. Built on top of the LSA settings management system, code-shared and also used at CERN, the system is kept generic. Furthermore, it is designed to support multiple accelerators, transfer lines and users in parallel. In particular, it can handle continuously changing optics and other in advance known changing beam parameters. The COAT computer program is part of a set of newly developed beam-based feedback tools* for FAIR. Preliminary results of our proof-of-concept prototype studies indicate, e.g., in view of the observed SIS18 machine reproducibility, that such a cycle-to-cycle feedback control scheme may be adequate also for the other FAIR accelerators and transfer lines. *see separate contribution by R.

	The 'Facility for Anti-Proton and Ion Research' (FAIR) presently under construction, extends and supersedes GSI's existing infrastructure.
