Paper Abstract

The main goal of the Hipparcos mission is to measure the position of 100 000 stars, down to magnitude 9, within an accuracy of 2 mas. Achievement of these performances is only possible by reducing sufficiently observation dead times due to straylight originated by earth or moon. After a brief description of the Hipparcos mission principles, this paper will describe how straylight protection requirements have been taken into account in the design of the Hipparcos telescope and in the development of the corresponding hardware. The logic and methods used to demonstrate compliance with straylight protection requirements will be presented and the tests methods and test hardware will be described. First test results will be briefly given.
