                                             II.          SCARAB (Scanner for radioactive budget) will study the radiation received and reflected back by earth.
                                            III.          SAPHIR (Sondeur Atmospherique du profil d’Humidite Interopicale par Radiometrie) will investigate the humidity present in the tropical atmoshphere.
                                            IV.          GPS-ROS (Global Positioning system – Radio Occultation system) from Italy will study the temperature & humidity at different altitudes.
Developed by SRM University Students in Chennai will help in understanding the global warming and pollution by studying the CO2 & CO present in the atmosphere.
               Integrated by IIT Kanpur students, Jugnu has a camera to take pictures of the earth to monitor  vegetation, reservoirs, lakes & ponds.
