Diwata-2 is a Philippine microsatellite under-development and scheduled to be launched in 2018. It will be the second satellite of the Philippine Scientific Earth Observation Microsatellite (PHL-Microsat) program after Diwata-1.

Development

The satellite is being developed by 11 scholars under the Philippine Department of Science and Technology (DOST) in cooperation with the Tohoku University and Hokkaido University in contrast to 9 DOST scholars who worked with Diwata-1, Diwata-2's predecessor.[1]

As early as December 2016, the development of the satellite is already ongoing.[2] Unlike its predecessor, Diwata-2 will take advantage of radio communication technology by carrying an amateur radio payload for disaster relief purposes.[1] The satellite will also host all embedded features of its predecessor.[2]

By January 2016, the satellite is now in the design phase, with the engineering model already being developed by the scholars in the Philippines. The model will be tested in Japan.[1] The satellite is undergoing structural development, and components evaluation and testing by June 2017.[3]

The flight model of the satellite is projected to be completed in December 2017.[1]

Instruments

Diwata-2 will host an amateur radio payload which will enable people in the Philippines to relay messages through ham radio to any part of the country. This function is meant for disaster relief operations. The satellite will also carry Spaceborne Multispectral Imager (SMI) with liquid crystal tunable filter (LCTF) for environmental monitoring, and a high precision telescope (HPT) for rapid post-disaster assessment. Compared to Diwata-1 which hosted wide and middle field cameras, Diwata-2 will host enhanced resolution cameras.[1]

Launch and mission

The satellite is targeted by the DOST to be deployed within the second quarter of 2018. It will have the same mission as its predecessor, Diwata-1. It will have a sun-synchronous orbit.[3]
