This stage ended with the flight model which was completed on August 29, 2018, and was handed over to the Japan Aerospace Exploration Agency (JAXA) on the following day.

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.

[6] The SMI, is equipped with an upgraded enhanced spatial resolution camera allowing the satellite to produce sharper images than the Diwata-1.

[10] The projected launch date was later adjusted at least twice; June 2018[11] and later pushed forward to fourth quarter of 2018.

It will also have a fixed visit interval time unlike its predecessor, meaning it will hover above the same position on Earth for every 16 days.
