The Spacelab Instrument Pointing Subsystem (IPS), currently under development for the European Space Agency by Dornier System, is designed as a facility-type pointing system. The IPS will be used for experiments of a mass of up to 2000kg with pointing requirements, which exceed the pointing capabilities of the Shuttle Orbiter. The nointing performance of the IPS will be in the arc-second region. In order to satisfy the various payload needs for nointing quite a number of pointing options, e.g. scanning, have been designed into the IPS software and hardware. This paper focusses on the operational capabilities of the IPS in a manner the experimenter needs to understand them, in order to utilise the IPS for his experimental work most beneficially. The operational modes will be explained, like the stellar, solar, and earth pointing mode together with their options for acquisition and pointing, experiment related pointing, manoeuvres, and contingency operations. Further, operator and user related services like error messages, telemetry and uplink commands will be detailed.
