The NASA Spaceshuttle (STS) will in 1983 have the ESA Spacelab onboard, Which will carry on one of its pallets a three, axes gimballed platform called Instrument Pointing System (IPS). The IPS will serve as a prcgrammable pointing system for the scientific user with a need for precise pointing of an instrument at a stellar Object or at Earth. The pointing error will be of an order of magnitude of 2 to 15 arc sec in function of disturbances, payload properties, and DS position in the Orbiter. The user of IPS will have access at the installation interface to electrical power and to the data and command processing facilities of Spacelab (SL).
