This paper presents the first part of a demonstration on "How to use Star Trackers to perform Space Surveillance". This part shows how to simulate the image taken by a Star Tracker placed on-board a spacecraft orbiting the Earth and how to use it for space surveillance. The simulation has to be accurate enough and take into account effects such as smearing and variable reflectivity of the object. Once the image is created and the usual treatments are performed, it can go to estimation routines and one can have an accurate idea of whether an object is detectable and whether its orbit can be estimated.
