Abstract. In this paper we describe the observational constraints imposed on the TAUVEX space telescope due to scattered light entering its telescopes from outside the field of view. This stray light is a sunlight reflected from various spacecraft components into TAUVEX apertures. Based on these constraints, a basic strategy of observation is suggested, in which the ma jor part of the observational time will be dedicated to sky survey, while the rest will be aimed at specific targets.
