Diwata-2

The satellite was 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. Unlike its predecessor, Diwata-2 takes advantage of radio communication technology by carrying an amateur radio payload for disaster relief purposes. The planning phase of the Diwata-2's development includes a simulation model, a mechanical test model, an engineering model and a flight model. 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. ==Instruments==

Weighing , ==Launch and mission==

The satellite was targeted by the DOST to be deployed as early as the second quarter of 2018. The projected launch date was later adjusted at least twice; June 2018 and later pushed forward to fourth quarter of 2018. It was announced that on October 26, 2018, the satellite would be launched to space via the H-IIA from Japan at the Tanegashima Space Center at around 13:08 and 13:20 (JST). Communication between the satellite and the DOST-ASTI's ground station in Quezon City was first established on October 29 at 21:52 (UTC+8). Diwata-2 will have the same mission as its predecessor, Diwata-1. It has a Sun-synchronous orbit It is designated with the amateur call sign DW4TA by the National Telecommunications Commission of the Philippines. ==See also==
