Mexican students to participate in satellite development in Japan

Mexico, Nov. 9 (Notimex).- The Mexican Space Agency (AEM, for its acronym in Spanish) reported that Mexican students were selected to participate in the design and development of the Ten-Koh satellite, which was launched by the Japanese Aerospace Exploration Agency (JAXA).

The director of the AEM, Javier Mendieta Jiménez, informed that the students are Isaí Fajardo Tapia and Rigoberto Reyes Morales, both doctoral students at the Kyushu Institute of Technology (Kyutech), in Kitakyushu, Japan, and who were selected for their talent in the compact team of 23 people from 13 countries.

"Rigoberto and Isaí have generously shared their knowledge with their Mexican colleagues since the start of their PhDs in Japan, which, like the forthcoming launch of the Mexican Nanosatélite AzTechSAT-1 from the International Space Station in 2019, demonstrates a steady increase in capacities in our youth to develop and launch more Nanosatélites, which will represent multiple benefits for our country. "

The Ten-Koh is a miniaturized satellite, of quasi-spherical shape, approximate mass of 23 kilograms, and structure mainly based on a carbon fiber composite (CFRP).

It was launched as a secondary load of the Japanese satellite GOSAT-2 "IBUKI-2" and the satellite Khalifasat of the United Arab Emirates, by means of the rocket H-2A number 40, from the space center of Tanegashima, in southern Japan.

Master Isaí Fajardo participated in the design of instrumentation for various payloads, in collaboration with other students and researchers, being in charge of the studies and preliminary estimates of the main experiments of the Ten-Koh mission and its requirements.

He also developed, in conjunction with an Algerian researcher, a system to measure plasma parameters in the orbit around the satellite, as well as the design and development of the hardware and software that controls two of the three main satellite experiments, the development of others subsystems, and the final design of various PCB cards, and their protection, for the operation of these in space.

In turn, master Rigoberto Reyes participated in the design, development, testing and integration of the orientation determination subsystem (ADS), as well as in the development of the algorithm by which the orientation of the satellite in space is determined.

This subsystem has the main task of providing two of the main experiments with the direction information of the satellite, important for the interpretation of the data obtained by said experiments.

The two Mexican students are part of the Space Engineering International Course (SEIC), a program of the Kyutech, which is part of the UNOOSA-Japan cooperation framework, called PNST (Post-Graduate Study on Nano-Satellite Technologies), focused on studies on Nanosatellites technologies.

The Ten-Koh satellite incorporates different payloads that make measurements of the plasma environment in the ionosphere and the variations of this around a rotating satellite.

As well as measurements of charged particles (electrons, ions and protons) in LEO orbit during the present solar minimum, and measurements of the degradation effects of new materials based on carbon compounds when exposed to the space environment.

It also carries secondary loads for demonstrations of new technologies applied to satellites and spacecraft, the AEM said in a statement.

The satellite, developed in the laboratory of Professor Okuyama in the Kyutech, in a time of one year and four months, began to transmit its signal and was received in Argentina, the United States, Germany, Brazil, Colombia, Europe, Japan, Indonesia, Mexico (with the help of the Mexican Federation of Radio Experimenters, FMRE) and Ukraine, confirming the correct operation of the satellite.

In the next two or three weeks, ground operations will be carried out to confirm the nominal operation of the device (early phase of operations), and then proceed to the normal operations phase, where, among other things, the ignition of the payloads will be carried out and of all subsystems on board that complement the experiments.
