For each object and epoch the program simulates position, kinematics and photometry. This step includes an Universe model and the scanning law and orbitals parameters of the satellite. Transformation from sky coordinates to instrument coordinates. This step includes the geometry and the optics of the instrument, together with the configuration of the field of view (FOV). Simulation of the observational process according to the instrumental parameters: detection, acquisition of data and telemetry. This step includes a model of the observational process.;Reference;GASS - Current status;Gaia Image and Basic Instrument Simulator;GIBIS Simulator;GIBIS Status;Priorities schedule;2001;Long term mission schedule;SWG priorities – immediate (2-3 months);SWG priorities – short term (2002-2005) I;SWG priorities – short term (2002-2005) II;SWG priorities – long term (2005 ?)
