• Abstract:

  PLATO (PLanetary Transits and Oscillations of stars)
  [1] is a European space mission with Brazilian collaboration focused on the search for exoplanets of the typeterrestrialin habitable zones of stars similar to the Sun. Conducted by the European Space Agency (ESA), it is scheduled for launch in 2026. One of the main products of the mission are the light curves of a large number of stars. The method used, fixed aperture photometry, aims maximized signal-to-noise ratio of light curves. For this purpose, several noises are considered, including those from the CCD detector (Charge-Coupled Device), zodiacal light and satellite movement (jitter). A method Compensation algorithm based on CoRoT satellite (CNES) algorithms was developed to correct photometric jitter noise. For the correct implementation of the method, it is necessary to use an Attitude Control System simulator. Such a simulator is under development within the scope of research dedicated to PLATO. It is in this context that the project, whose objectives are the development of a graphical user interface and its integration into the PLATO mission Attitude Control System simulator. It is expected with this work that the use of the simulator within the consortium of the mission can be carried out by non-control specialists, and in support of the development of many different mission instrumental correction algorithms.
