We provide support in both hardware and software aspects for system designs, inspections/tests, and operations/evaluations of artificial satellites for space development, work on the International Space Station and sounding rockets.
We utilize our technology, trust, and achievements accumulated in the space business industry
I-NET began its space development service with the satellite operation project for the geostationary meteorological satellite "Himawari," which was launched in 1977. In the roughly 40 years to date, we have conducted system/subsystem designs, inspections/tests, and operations/evaluation analyses of many artificial satellites. We have also developed many software programs such as software to process image data/satellite condition data acquired by artificial satellites and software to manage rocket launch control systems. By utilizing such information through I-NET's proprietary data centers, we can provide one-stop support from system designs to evaluations and analyses.
We have also worked on the International Space Station from its original construction to the current operations. We aim to work in the field of manned space missions on the moon and Mars in the future.
Following the first asteroid probe "Hayabusa" project that returned to Earth in 2010, I-NET participated in the asteroid probe "Hayabusa2" project that returned to Earth in December 2020. In the Hayabusa2 project, we are involved in the development and operation of the asteroid probe.
An ultra-small land and marine observation satellite project, proposed by a team whose representative proposing organization is Tokyo Institute of Technology that includes I-NET as a member, was adopted as a demonstration theme for Innovative Satellite Technology Demonstration Unit No. 3 of the Japan Aerospace Exploration Agency, a National Research and Development Agency (JAXA).
I-NET will be responsible for its satellite operations (design, tests, operations, etc. of the satellite system). After its launch in FY 2022 from JAXA's Uchinoura Space Center on the Epsilon Launch Vehicle, this satellite is scheduled to be operated for two years to serve on its missions.
We have invested in Astroscale Holdings to strengthen our relationship. Astroscale Holdings is the world's first private company that aims to leave sustainable orbits for the next generation by achieving a service to remove space debris that continues to increase on the orbits, aiming to ensure safe traveling of rockets and artificial satellites in space. I-NET provides support, including the assembly, testing, and operation of space debris capturing satellites, while supporting the operation of ground station facilities, including parabola antennas installed on our premises.
We have formed a capital and business alliance with SPACE WALKER, a company that aims to achieve Japan's first manned spaceflight by developing a spaceplane on which anyone can travel to space as easily as traveling on an airplane.

Earth observation satellites
Earth observation satellites survey the surface of the Earth from far above in space, observing a variety of events, such as weather and disaster monitoring. I-NET has a track record of working on various Earth observation satellite projects.
Related satellites: land observation satellite, marine observation satellite, environmental observation technology satellite, aurora observation satellite, etc.
Scientific satellites aim to demystify distant space, such as by planet explorations and astronomical observations, using satellites that feature observation equipment and data collection equipment. I-NET has a track record of working on various scientific satellite projects.
Related satellites: asteroid probe, x-ray astronomy satellite, astronomical observation satellite, lunar orbiter satellite, etc.
Navigation satellite: Quasi-zenith Satellite-1 "Michibiki"
Commonly used for car navigation systems, the GPS using navigation satellites are essential to our lives. To be used in Japan, navigation satellites equipped with features to complement the positioning improves the precision of the GPS. I-NET has a track record of working on various scientific satellite projects.
International Space Station (ISS)
An international space project with 15 countries worldwide participating, the International Space Station is a massive manned experiment facility constructed approximately 400km above the Earth's surface. While orbiting the Earth at the speed of roughly 90 minutes per orbit, researchers in the ISS conduct experiments and research, as well as observations of the Earth and other celestial objects. I-NET is involved in the operational duties of the Japanese experiment module, Kibo.

In recognition of the contribution by the Asteroid Explorer "Hayabusa," I-NET received a letter of appreciation from the Minister of Education, Culture, Sports, Science and Technology and the Minister for Space Policy.
We provide support in both hardware and software aspects for system designs, inspections/tests, and operations/evaluations of artificial satellites.
Unlike the surface of the Earth, the environment in space where artificial satellites and probes work is a vacuum. The temperature rises to an extreme high when hit by the sunlight, while sharply dropping to an ultra low in the dark, resulting in a difference of approximately 250 degrees Celsius. When exploring planets, probes may face significant load at the time of separation, landing, and entry. In addition, satellites and probes are subjected to harsh environments when they are launched on rockets, with acceleration, vibration, impact, and acoustics. I-NET provides support for system designs, inspections/tests, and operations/evaluations of artificial satellites and probes.
Design, development, and operation services require advanced knowledge and experience so that artificial satellites and probes can fulfill their required missions even under harsh conditions. I-NET provides various design services with experience and knowledge in space development accumulated over many years.
Artificial satellites and probes cannot be repaired after they have been launched into space, even if some defects are found. I-NET conducts various inspections and tests with years of experience as well as high level of expertise and qualifications. We prove the features of artificial satellites and probes have been installed properly and also prove they can properly function even under harsh conditions at the launch on rockets or in space.
