Philippines to deploy Diwata-1 sat from ISS in April 2016


Philippines: Philippines is all geared up to deploy the country’s third satellite from International Space Station Kibo module in April 2016 according to Department of Science and Technology (DOST). The satellite named Diwata-1, is the result of mutual cooperation between DOST, University of Philippines, Hokkaido University and Tohoku University. The one of its kind, Diwata-1 is the first microsatellite that is completely built and designed by Filipinos.

It will be LEO satellite with weight at around 50 kg and operating from 400 km orbit. Command upload will be performed on UHF band. The satellite will feature High Precision Telescope (HPT) equipped with four CCD (for each red, green, blue and near infrared) will operate with resolution up to 3 m at 400 km will serve for general disaster monitoring. A space-borne MultISPectral Imager (SMI) with Liquid Crystal Tunable FiLTEr (LCTF) with resolution of 80m at 400 km will help in observing vegetation and measuring changes in phytoplankton biomass of the Philippines oceans. Its Wide Field Camera (WFC) with single panchromatic CCD with 7 kms of resolution will observe the clouds and weather phenomena. Middle Field Camera (MFC) is last payload and it includes colour CCD with resolution of 185 m which will be used for calibrating attitude determination algorithm and supporting HPT and SMI.

The satellite is designed by Hokkaido University and Tohoku University, with the objective of using it for monitoring natural disasters in South East Asia. The program is based on partnerships of different research institutes, universities and government agencies from Bangladesh, Indonesia, Malaysia, Myanmar, Mongolia, Philippines, Thailand, and Vietnam.

Most important objectives of Diwata-1 is monitoring natural phenomenon, gathering data for agriculture and weather forecasting. Data gathered by satellite will be downlinked to control center daily. Another goal of Diwata-1 mission is developing own space research institutes and eventually establishing Philippines space agency in future.

After the assembling of the satellite, it will be send to NASA for final testing. Satellite will not be launch as a secondary payload or in any conventional way. It will be launched onboard Dragon Spacecraft and delivered to ISS. Next it will be deployed from Kibo module and remain operating for 18 months. Ground control center will be provided by JAXA and located in Tohoku University (Ground station (CRESST)), additional ground stations will be Philippines Earth Data Resources Observation (PEDRO) station located in Subic, Zambales which will also responsible for receiving and storing data from Diwata-1. It is planned that next satellite, Diwata-2, will be launched on 2017.
