Proceedings of International Conference on Artificial Life and Robotics ( ALife Robotics Corporation Ltd. ) 28 846 - 851 2023.02

Language：English Publishing type：Research paper (scientific journal)

Because of its communication volume constraints, scientific observations by nanosatellites need to reduce downlink data by onboard data preprocessing. Therefore, we tried to classify time series data of the geomagnetic field obtained by the SWARM satellite to determine the most appropriate method for onboard classification of a phenomenon in the geomagnetic field. The classifications have been executed using rule-based, K-means, and combined CNN methods. The experimental results demonstrated the effectiveness of the machine-learning model with LSTM networks.

This paper reports the activities resulting from satellite communication lectures conducted by the KOSEN space group in January and August of 2018. Since 2014 the KOSEN space group has been developing two CubeSats to educate students and to complete scientific missions. Consequently, the aim of our lectures is to enable KOSEN students to monitor and operate the CubeSats by satellite communication. In the January lecture, students learned satellite communication theories, and practical training on the assembly and operation of simple receivers. In August, the students learned the theories of digital satellite communication and participated in advanced training using the simple receivers. A survey indicated the participants are interested in receiving signals from a real satellite in space, using the simple self-assembled receivers.

This paper describes the “2017 and 2018 KOSEN Space Camps.” These camps offer introductory space technology programs for students enrolled in the various KOSEN technology colleges in Japan. Since 2015, we have hosted this camp at the Marine Park Niihama. Over the last two years, we evolved and refined the camp's contents to develop a more effective space technology and science education program. In 2017, we successfully held two CanSat development courses: One for beginners to learn how to use onboard computers and sensors and one that is driven more by the participants' imaginations. We tried to make our camps stand out in terms of content variations and load balances including competition. In 2018, we attempted to introduce advanced content such as model CubeSat development and competition. This new trial included online preparation materials from KOSEN's space academia. We will continue to improve the Space Camp content so that in the future, this program may be established as an annual space event in Niihama City.

Proceedings of International Conference on Artificial Life and Robotics ( ALife Robotics Corporation Ltd. ) 25 75 - 78 2020.01

Language：English Publishing type：Research paper (scientific journal)

We report the development of a model CubeSat for satellite communication education. The communication between satellites and ground stations is an essential part of satellite operations. As a critical part of the satellite systems, we focused on satellite communication to train the student so that they can develop and operate the CubeSats. The model CubeSat is equipped with fundamental components, such as an onboard computer, sensors, communication, and power supply, which are necessary for satellites. The software programs in the model CubeSat provide two functions: controlling and monitoring satellites, and transmission of telemetry and image data. The students can study the communication equipment and operations of satellite communication using our model CubeSat.

Language：English Publishing type：Research paper (scientific journal)

Currently, 10 National Institutes of Technology (KOSEN) are collaborating to develop a 2U CubeSat. This study aims to develop a CubeSat ground model that allows KOSEN students who wish to participate to learn CubeSat. The CubeSat ground model is a standard 10cm×10cm×20cm (2U) CubeSat size. Furthermore, it consists of a similar subsystem as the actual CubeSat, enabling semi-autonomous operation by OBC, charging and feeding by solar cells, and data transmission by wireless devices. Moreover, a structure system with a space where mission equipment can be installed will be designed, so that students can deepen their understanding of the satellite mission. These plans will be used in the model CubeSat production course at the KOSEN Space Camp 2019. This paper describes features of the developed model CubeSat and introduces the model CubeSat production course.

In this study, cheap and easy-to-use CubeSat educational materials are developed for students studying satellite development, for the first time. The developed model CubeSat is slightly larger than 1U size, and comprises multiple subsystems similar to a real satellite. In addition, model CubeSat competitions on the power supply, communication, and attitude are designed and conducted, where the respective subsystems are applied. The questionnaire results indicate that the model CubeSat assembly course and competition are popular and beneficial for the students.

Language：Japanese Publishing type：Research paper (scientific journal)

We report on a practical example of an online engineering-related manufacturing course: a production course for CanSat, an extremely small satellite model. Conducting online manufacturing courses is an effective tool for technical education. To spread space technology education nationwide, CanSat courses are held via online conferences. For students, the kit and the fabrication manual for the CanSat course were improved; in addition, the work procedure manual and documentation for instructors were enhanced. For this course, students experienced preparing the educational kits and teaching the CanSat course themselves, practicing for the course through product preparation. In this paper, we summarize the results of the CanSat course from preparation to implementation, and propose improvements for future courses.

Example of an Online Manufacturing Course in Engineering:: The CanSat Production Course in Space Technology Education Reviewed International journal

SASAOKA Yui, UEZONO Namiki, KAJIMURA Yoshihiro, NAKAYA Jun, KITAMURA Kentarou, UETA Shinya, TAKADA Taku

Language：English Publishing type：Research paper (scientific journal)

This report examines a practical example of an online engineering production course for students. Typically, production courses in fields such as manufacturing provide students with hands on training in a laboratory setting. While it is now possible to conduct lectures and meetings online, this is not yet the case with production courses. To fill this gap, we conducted an online CanSat pico-satellite manufacturing course in the field of space personnel training. We then examined the possibility and effectiveness of future refinements for similar online production courses, based on participant responses to questionnaires about problems peculiar to remote production courses.
