Space Electrical and Electronic Radio Laboratory (Yoshihiro Tsuruta Laboratory)

As part of our graduation research and master's thesis research, our laboratory is engaged in basic research on mission studies of various artificial satellites, system design, component design / verification, low-cost ground station design / operation, and elemental technologies related to them. is.
Among the elements that make up an artificial satellite, in particular, the elements related to the three "electricity" of electricity, electronics, and radio waves control the basic functions of the artificial satellite, and at the same time, the functions and performance of advanced microsatellite. It is an indispensable point to pursue. In addition, microsatellite with a standard called CubSat, which has a basic shape of 10 cm square, which has become popular for commercial use in recent years, is required to pursue high functionality and high performance due to the limited volume. Innovative ideas regarding the miniaturization of electronic and communication equipment to be installed are needed. In addition, artificial satellites that are smaller than the CubeSat and fit in the palm of your hand have begun to be launched and operated, and the need for miniaturization is increasing. Therefore, in our laboratory, we have positioned a class smaller than "microsatellite" as "microsatellite", and are proceeding with conceptual design and system studies with the aim of future orbital demonstration.
By belonging to this laboratory, you can acquire a wide range of knowledge and experience that will be useful even after graduation through the development of microcomputers and the design, testing, and evaluation of electronic circuits and antennas.
We are also participating in the Teikyo Sat-4 project under development at our university, and you can also experience research and development through practical project experience.

Basic Information

Our Research

Ultra-small artificial satellite development project
The Teikyo Sat series under development at our university is a 50 cm class artificial satellite, but we are considering a microsatellite mission system to realize some of its functions with a smaller Form factor. As the size of a satellite increases, it can have more functions, but it is inevitable that there will be fewer opportunities for launch and higher costs. Therefore, although the functions and performance are limited, the cycle is faster than the 50 cm class artificial satellite by utilizing CubeSat and even smaller ultra-small size artificial satellites, which have low launch cost and high launch frequency. The merit is that the elemental technology can be demonstrated in space and the knowledge generated there can be fed back to a 50 cm class artificial satellite. Ultimately, we are aiming to realize a system design that fits in the palm of your hand and to demonstrate it in orbit by 2025.

Low cost ground station system development project
Currently, the number of micro-satellite launches is exploding, and in the future, when the number of artificial satellites increases, the number of ground station systems for acquiring data will inevitably increase. Is required to be. Therefore, in our laboratory, we are developing a low-cost ground station system compatible with S-band, C-band, and X-band for communication with satellites.
We are aiming to realize a low-cost ground station system with end-to-end antenna elements, drive trains, and signal processing, and to install multiple machines on campus so that they can actually be operated.
