The present invention relates to a method for configuring a model for the interpretation of the interfering light in the orbit of a geostationary ocean observing sensor by applying an integrated optical tracking module. The method includes the steps of : building a statistic optical ray track simulation of the optical paths of rays emitted from the sun to the earth through a solar model; building a statistic optical ray track simulation of the optical paths of rays which reached the earth from the sun and are reflected and scattered before reaching an optical system in a geostationary orbit through an earth model; and using the properties of the signals reaching the optical system acquired through the solar and earth models and optically tracking the rays in the optical paths of the optical system reaching the surface of a detecter to determine an irradiation object or a threshold object with the highest possibility of being exposed to the interfering light.(AA) Observation target - earth(BB) Light soure - sun(CC) Optical system - GOCICOPYRIGHT KIPO 2015
