One of the most important strategic development technologies to fight any future war in space is to be able to swarm LEO, MEO and GEO with ASATs, spy, communications and defensive satellites. More exotic than tactical warfighting is the prospect of an orbital arms race where contesting powers build up their counterspace (defensive and offensive) capabilities.

Presently we are in the era of a slow-motion arms buildup with various nations including Japan flexing their muscles with cramming more capability into smaller and smaller satellites. In line with this last June’s Basic Plan for Space Policy focused Japan’s sites on  microsatellite development by universities, and UNIFORM follows on from a 4.1 billion yen FIRST program investment by the Cabinet Office in university-based nanosatellite development, which ends in 2013.

The result is the UNIFORM (University International Formation Mission) program explained below.

It is a fact that the brilliant Shinchi Nakasuka (here is a nice puff piece at JAXA), who is the man most behind Japan’s strategic microsatellite development at Tokyo at the ISSL and UNISEC already got most of that money for FIRST and now my best guess that it will get the lion’s share for UNIFORM.

But there are actually several things going on with UNIFORM, according to my knowledge

1. UNIFORM was needed because of the failure of MicroStar, a more bureaucratic version run by JAXA, which was not pulling in the customers.

2) Any diplomatic offensive using the Asia-Pacific Regional Space Agency Forum (APRSAF) is welcome by Japan as a classic MOFA strategy- a regional “balancer” against and diluter growing Chinese soft space diplomacy. In particular the Japan-originated APRSAF got the reputation of being a bit of a talking shop compared with Asia-Pacific Space Cooperation Organization (APSCO) which has the reputation of getting things done.

As METI already secured a big tranche of yen for the ASNARO constellation, which is NEC’s answer to the not very functional Melco IGS constellation, it would seem that Japan is going gangbusters to develop small-bus technology for intelligence gathering, observation, communication and more exotic applications.

Japan Advances University-led Microsatellite Constellation

TOKYO — A Japanese government-funded consortium of universities aiming to launch a constellation of scientific microsatellites starting in 2012 is looking for Asian partners to join the program, according to project leaders.

The University International Formation Mission (UNIFORM) project was established in Japan this summer and formally announced in November at the 17th Session of Asia-Pacific Regional Space Agency Forum in Melbourne, Australia.

At its core, the UNIFORM project aims to field a functional satellite constellation and ground station network that will yield usable data at a fraction of the price of commercially built satellites. More broadly, project organizers expect UNIFORM to energize Japan’s capacity for building microsatellites and spread that know-how throughout Asia through international cooperation, according to Hiroaki Akiyama, a professor at Wakayama University in western Japan, which is leading the project in conjunction with six other Japanese universities.

“UNIFORM is about microsatellite community building,” Akiyama told Space News Dec. 1. “We will build a closely bonded network of microsatellite technology, microsatellite people, and microsatellite utilization. It is one of our purposes to initiate a paradigm shift in the space business model which only succeeded with stationary satellites in the past. This network has the potential to change the space industry in the near future.”

The UNIFORM consortium aims at initially launching groups of 50-kilogram-class satellites in pairs or clusters in 2012 and 2014 to build a constellation capable of frequent revisits for Earth observation or atmospheric monitoring missions,  Kanenori Ishibashi, a research engineer at the University of Tokyo, said Dec. 1. The university is another leading member of the consortium. The project is still in the planning stage, and organizers are actively hunting partners around the region so that satellite and mission development can begin next summer, he said.

UNIFORM was approved by Japan’s Ministry of Education, Culture, Sports, Science and Technology (MEXT) in October with a budget of 300 million yen ($3.5 million) per year over five years as part of a government effort to bolster Japan’s university-based microsatellite community, said Shigekazu Matsuura, director of the Office of Space Utilization at MEXT, in a Nov. 30 interview.

Following the release of Japan’s Basic Plan for Space Policy in June 2009, the Japanese government has continued to fund microsatellite development by universities, and UNIFORM follows on from a 4.1 billion yen investment by the Cabinet Office in university-based nanosatellite development, which ends in 2013.

Matsuura said MEXT is engaging in a form of “space diplomacy” funding the UNIFORM program’s efforts to build up microsatellite expertise in the Asia-Pacific region.

“[Research and development] of microsatellites is very suitable for fostering young engineers and international diplomacy while increasing our earth observation frequency,” said Matsuura, who takes credit for originating the program.

Announcing the project at the Asia-Pacific space agency forum in Melbourne in November was an important step in gathering partners to define the mission and start building pan-Asian cooperation, Ishibashi said.

“We did have very good responses from about a dozen people/organizations in the Asian-Pacific region,” he said. “This means that now we have a chance to start forming a strong multinational micro/nanosatellite community [in Asia] that is focused not only on the engineering and science aspect but also the practical utilization of data and signals.”

Japan’s university-based microsatellite community dates back more than a decade, with most activities coordinated under the Tokyo-based University Space Engineering Consortium, which comprises 47 laboratories from 38 universities that are steadily building increasingly functional satellites faster and cheaper, Ishibashi said.

Asian-Pacific nations joining UNIFORM will develop their own satellites with Japanese partners on hand to provide required technologies for standardizing satellite equipment.

Ishibashi said participating nations will share with Japan the cost of building the UNIFORM microsatellites, which are expected to cost between 50 million and 200 million yen.


JAXA was due to take another important step forward in its informal Operationally Responsive Space Program (ORS) (dubbed SOD, or Space on Demand, by some sources) this morning with the test of J-POD, the JAXA Picosatellite Deployer, on board the PLANET-C/ Akatsuki Venus climate monitoring mission and the IKAROS (Interplanetary Kite-craft Accelerated by Radiation of the Sun) solar sail test mission.

While the media has focused on Akatsuki and IKAROS, this latest outing by the H-IIA (H-IIA F17) is strategically significant in the testing of next generation ORS technologies through J-POD, that is to say, the ability to sprinkle/disperse micro- and picosatellites into different orbits.

It’s the J-POD, not the PPOD, that’s most the most interesting part of this mission from a strategic perspective as it is imperative that Japan continue to develop and test micro- and picosatellite deployment technologies and scenarios for the ASR/Epsilon. Also J-POD and future iterations will also allow the MOD or other stakeholders to discretely launch and deploy future warfighting and counterspace payloads. These may or may not be embedded in civilian formation flying missions, etc. Since the MOD has shown a strong interest in microsatellites for SSA and ORS, it’s important that Japan keep on running these dual-use technology demonstrator programs.

In today’s attempted launch (currently postponed because of icing fears) J-POD will release three small secondary payloads: WASEDA-SAT2, K-Sat and Negai, before injecting Akatsuki into Venus transfer orbit. The H-IIA will continue its coast flight and separate the IKAROS and UNISEC’s UNITEC-1 from the Payload Attach Fitting (PAF900M).

The growing prowess of JAXA in injecting completely heterogeneous missions into very different orbits is duly noted.

Also, let’s not forget the satellites themselves, part of Japan’s thriving and bubbling microsatellite building knowledge infrastructure, which truly seems to be burgeoning. This set of missions is interesting from a number of angles. Firstly we now have non-elite universities developing picosatellite technology- both Negai, by Soka University and K-Sat by Kagoshima Universities are 1kg-class picosats. K-Sat is interesting because despite being only a single unit CubeSat, it will be able to perform multiple (if simple) missions, including studying water vapor in the Earth’s atmosphere, and conduct microwave imagery and spacecraft communications tests.

Waseda-SAT2 is much more interesting in that it will perform both an EO mission and test the use of attitude control with the use of extendible paddles. The importance of this hardly needs stating.
