Abstract

A key component of the Gaia mission development is its simulator. This system can generate a realistic simulation of the data stream that will be produced by Gaia, a critical milestone to verify the data reduction programs. A core piece of the simulator is its universe model, a module that can generate synthetic catalogues of objects to obtain simulated observations. GUMS is the application that can generate the object catalogue up to a particular magnitude limit. As a example of application that uses the model, we describe GOG, a simulator of Gaia catalogue intermediate and final data. It combines the source observation of the universe model with the satellite instrumental specifications and the available error models.
