Equatorial regions are located in a band around the Equator and cover about 6% of the Earth’s surface. They are often in lowland areas and have a climate that is hot and wet all year round. Cloud cover is a major problem for optical or passive sensors. These sensors require an external light source to illuminate the ground. They also need to be able to see the ground to produce images of ground level events. Overcrowding of wireless devices signals interfere with cosmic radio signals for Earth Observation data. Other problems include inconsistent sun angle, thermal control, low re-visit frequency and etc. In the events of disasters such as landslides, flooding or forest fire, interferences with capturing EO data could affect rescue efforts.
