Remote sensing activities from satellite are important aspect togain information about earth surface, thus has important significance on military, economic and geology fields. After 1962, the term remote sensing became popular and typically refers to non-intrusive observation of the Earth using electromagnetic waves from a platform some distance away from the object of study. Remote sensing implies a measurement made by some indirect or “remote” means rather than by a contact sensor. Remote sensing platform of satellite serves the sensing by using sensors. There are two types of sensors active and passive sensors. This article reviews about the sensors which are used for remote sensing of earth from satellite. This article analyses the sensors for sensing purpose and for attitude control of the satellite.
