Diwata-1 is a Philippine microsatellite deployed into orbit from the International Space Station (ISS) on April 27, 2016. It is the first 50kg satellite of the Philippine Scientific Earth Observation Microsatellite (PHL-Microsat) Program, a three-year research and development program funded by the Department of Science and Technology (DOST) of the Philippines. The program is a collaboration between the University of the Philippines, the DOST-Advanced Science and Technology Institute (DOST-ASTI), and Japan’s Tohoku University and Hokkaido University. Diwata-1 has three optical instruments for scientific earth observation: the High Precision Telescope (HPT) which can be used in studying the extent of damages from natural disasters; a Space-borne Multispectral Imager (SMI) with Liquid Crystal Tunable Filter (LCTF) for assessing changes in vegetation and ocean productivity studies; and the Wide Field Camera (WFC) which can capture cloud patterns and weather disturbances. It is also equipped with one engineering control instrument, the Middle Field Camera (MFC), which is used to help locate the images captured by HPT and SMI.
