PH marks first year of Diwata-2 micro-satellite in space

The Philippines observed the first anniversary in space of Diwata-2, the country’s second micro-satellite, in simple ceremonies at the University of the Philippines Diliman Electrical and Electronics Engineering Institute (UP-EEEI) on Tuesday, October 29.

Diwata-2 is a 50-kilogram Earth observation micro-satellite built by a team from UPD and the Advanced Science and Technology Institute of the Department of Science and Technology (DOST-ASTI), in cooperation with Tohoku University and Hokkaido University in Japan. It was deployed into 600 km Sun-Synchronous Orbit on October 29, 2018.

Development of the micro-satellite began under the research program, “Development of the Philippines Scientific Earth Observation Microsatellite (PHL-Microsat)” and was completed under the “Space Technology & Applications Mastery, Innovation and Advancement (STAMINA4Space)” program, which continues to operate the micro-satellite along with its predecessor, Diwata-1.

Both programs are funded by the DOST Grants-in-Aid (DOST-GIA) and monitored by DOST’s Philippine Council for Industry, Energy and Emerging Technology Research and Development (PCIEERD). It is the Philippines’ third satellite sent to space, following the 50 kg. micro-satellite Diwata-1 (deployed to space April 27, 2016) and the 1 kg nano-satellite Maya-1 (deployed on June 29, 2018).

As a “science satellite” built in an academic environment, Diwata-2 is primarily intended to conduct scientific measurements and experiments for environmental assessment and monitoring, which can be carried out by its on-board cameras.

In its first year in space, Diwata-2 has acquired images covering 46.06% of the Philippines, which are being distributed in this website . Current registered users on the website have reached over 800, which span researchers, academic institutions, government, non-profit organizations, industry groups and the general public.

Diwata-2 also carries an amateur radio unit (ARU), which can be used by amateur radio hobbyists and first responders as an alternative means of communication during disasters. The ARU payload has seen increasing uptake from various users, with ham radio enthusiasts actively posting and sharing their experiences with Diwata-2 in social media and online platforms. The STAMINA4Space team continues to conduct outreach activities to further promote the use of the Diwata-2 ARU.

In her opening message, DOST undersecretary for research and development Rowena Guevara said, “The event’s theme, ‘Translating knowledge to local technologies and applications’ captures what the team has been doing since then.”

“We hope to continue this momentum by fostering more local and international linkages and choosing more skilled and passionate researchers in this field in paving the way for future satellites, not only future Diwatas but possibly even more sophisticated satellites that bear the names of more Philippine icons that can proudly symbolize how far the Filipino stamp of ingenuity and innovation can take us,” she added.

The researchers’ presentations aimed to show just that, which STAMINA4Space PHL-50 project leader Marc Talampas then summarized in numbers:

  • 13 — the number of satellites that are either in orbit, in the lab as engineering models, or under development nurtured by Filipino hands;
  • 46.06% — the percentage of Philippine land area Diwata-2 has captured;
  • 672 — the number of screws that had to be checked after every vibration test during Diwata-2’s development (an example of meticulous engineering rigor needed);
  • 3 — the “trinity of vision” — light source, object, and detector (basic principles that Diwata-2’s optical payloads operate under); and
  • 101 — for Philippines-Oscar 101 (PO-101), which was designated by AMSAT to Diwata-2’s ARU on April 11 this year.

Guided tours of the University Laboratory for Small Satellite and Space Engineering Systems (ULyS3ES) facility were also opened to the public in the afternoon to interactively showcase the technologies on-board the micro-satellite, as well as the localization efforts being made by the STAMINA4Space Program’s different project teams.

Over 40 people were accommodated, including grade school to college students, faculty members from some Metro Manila schools, and general STEM enthusiasts.

STAMINA4Space Optical Payload Technology, In-Depth Knowledge Acquisition and Localization (OPTIKAL) project leader Maricor Soriano weighed in on what she believes is the most important output of the continuous development of satellites like Diwata-2.

“More than having our own satellite, I would like to emphasize that what’s more important… ay hindi iyung satellite — it’s the people. Kasi po pag marunong gumawa ng kahit ano itong ating team, kahit ano pa iyung ipagawa mo sa kanila, kaya nila. It’s really the investing in the people na ang pinakaimportante na output nitong program na ito,” she said.

STAMINA4Space program leader and DOST-ASTI acting director Joel Marciano, Jr. also highlighted the importance of space technology research in developing people, data and industry, representing three innovation thrusts of the STAMINA4Space program.

“If we don’t start and sustain this, we will forever be consumers of technology and data provided by other countries,” he said as he offered perspectives on how space technology can feed into the local innovation ecosystem.

“We aim to derive economic benefits from space — getting data, building electronics and instruments that can feed into industry through differentiated products and services, training people like the young people that you see here — so that we are not continuously left behind. The future lies in getting data and information from wherever we can get it (and) that includes the strategic vantage point of space.”
