We simulated the data outputs of the first Japanese astrometry satellite Nano-JASMINE,which is scheduled to be launched by the Cyclone-4 rocket in August 2011. The simulationswere carried out using existing stellar catalogues such as the Hipparcos catalogue, theTycho catalogue, and the Guide Star catalogue version 2.3. Several statics are shown suchas the number of stars those will be measured distances using annual aberrationobservations. The method for determining the initial direction of the satellite’s spinaxis has also been discussed. In this case, the frequency of bright stars observed by thesatellite is an important factor.
