Tropical Earth Resources Satellite (TERS)
Abstract
It is noted that the zero-degree inclination orbit at an altitude of 1680 km will have an orbital period of 120 min. The swath-width of the high resolution multispectral instrument can be pointed anywhere between 10 deg N and 10 deg S; this will offer the equatorial countries an opportunity to observe a part of their territory four times each day. The high cloud cover percentage in the tropics will lower this frequency, but a forward-looking cloud sensor will make it possible to detect the area that is free of clouds and to point the instrument field of view accordingly.
