-Sun simulator is a light source ​providing ​a beam of light for a number of characteristics similar to the solar one in order to influence the model orientation system ​and the conditions of shooting [[sim_earth|the globe]] sections with a [[camera_subsys|camera]] installed in the satellite model.+The sun simulator is a light source ​that provides ​a beam of light with a number of characteristics similar to solar characteristics ​in order to influence the orientation system ​of the model, as well as the conditions of shooting [[sim_earth|the globe]] sections with a [[camera_subsys|camera]] installed in the satellite model.
