Summary
The Space-astrometry satellite HIPPARCOS, which is being developed by the European Space Agency, will perform systematic observations of about 100,000 preselected stars over a period of 2.5 years.
An important and complex function to be implemented on board of the satellite is the selection in real time of the stars to be observed and the allocation to them of appropriate observation times.
This function is performed by what, in the HIPPARCOS terminology, is called the Star Observation Strategy (SOS) algorithm.
The present paper describes in detail the SOS selected for HIPPARCOS.
After a short description of the main mission concept, the requirements and constraints which have been considered in the selection of the SOS are discussed. The SOS algorithm is then introduced and the general conclusions which can be drawn from the results of extensive simulations performed with realistic data are finally indicated.
