Nanosatellites are proliferating as low-cost, dedicated remote sensing opportunities for small nations. However, nanosatellites’ performance as remote sensing platforms is impaired by low downlink speeds, which typically range from 1200 to 9600 bps. Additionally, an estimated 67% of downloaded data are unusable for further applications due to excess cloud cover. To alleviate this issue, we propose an image segmentation and prioritization algorithm to classify and segment the contents of captured images onboard the nanosatellite. This algorithm prioritizes images with clear captures of water bodies and vegetated areas with high downlink priority. This in-orbit organization of images will aid ground station operators with downlinking images suitable for further ground-based remote sensing analysis. The proposed algorithm uses Convolutional Neural Network (CNN) models to classify and segment captured image data. In this study, we compare various model architectures and backbone designs for segmentation and assess their performance. The models are trained on a dataset that simulates captured data from nanosatellites and transferred to the satellite hardware to conduct inferences. Ground testing for the satellite has achieved a peak Mean IoU of 75% and an F1 Score of 0.85 for multi-class segmentation. The proposed algorithm is expected to improve data budget downlink efficiency by up to 42% based on validation testing.

The radiation belt, where the high-energy particles are predominant in near earth space from the low earth orbit (LEO)to the geostationary orbit (GEO), sometimes causes satellite malfunction. Therefore, the objective of this study is to predict the high-energy electron flux at GEO with the energy above 2 MeV after 24 hours with higher accuracy for the safety satellite operation in terms of the space weather science. In this study the various kinds of solar wind data from satellite observations and ground geomagnetic observation data in 1999 were used for the Recurrent Neural Network (RNN). Prediction results were evaluated by the prediction efficiency, which is derived from both predicted and actual variation data. As a result, the prediction using combined data of solar wind and geomagnetic data shows highest prediction efficiency of 0.72.

The scientific g oal o f V ERTECS i s t o reveal the star-formation history along the evolution of the universe by measuring the extragalactic background light (EBL) in the visible wavelength. Earlier observations have shown that the near-infrared EBL is several times brighter than integrated light of individual galaxies. As candidates for the excess light, first-generation s tars in the early universe or low-redshift intra-halo light have been proposed. Since these objects are expected to show different e mission s pectra i n v isible w avelengths, m ulti-color v isible o bservations a re c rucial t o r eveal t he origin of the excess light.

In VERTECS mission, we develop a 6U CubeSat equipped with a 3U-sized telescope optimized for observation of the visible EBL. The bus system composed of onboard computer, electric power system, communication subsystem, and structure is based on heritage of series of CubeSats developed at Kyushu Institute of Technology in combination with high-precision attitude control subsystem and deployable solar array paddle required for the mission. The VERTECS mission was selected for JAXA-Small Satellite Rush Program (JAXA-SMASH Program), a new program that encourages universities, private companies and JAXA to collaborate to realize small satellite missions utilizing commercial small launch opportunities, and to diversify transportation services in Japan. We started the satellite development in December 2022 and plan to launch the satellite in FY2025.

Nanosatellites are proliferating as low-cost dedicated sensing systems with lean development cycles. Kyushu Institute of Technology (Kyutech) and collaborators have launched a joint venture for a nanosatellite mission, Visible Extragalactic background RadiaTion Exploration by CubeSat (VERTECS). The primary mission is to elucidate the formation history of stars by observing the optical-wavelength cosmic background radiation. The VERTECS satellite will be equipped with a small-Aperture telescope and a high-precision attitude control system to capture the astronomical data for analysis on the ground. However, nanosatellites are limited by their onboard memory resources and downlink speed capabilities. Additionally, due to a limited number of ground stations, the satellite mission will face issues meeting the required data budget for mission success. To alleviate this issue, we propose an on-orbit system pipeline to autonomously classify and then compress desirable image data for downlink prioritization and optimization. The system comprises a prototype Camera Controller Board (CCB) which carries a Raspberry Pi Compute Module 4 which is used for classification and compression. The system uses a lightweight Convolutional Neural Network (CNN) model to classify and determine the desirability of captured image data. The model is designed to be lean and robust to reduce the computational and memory load on the satellite. The model is trained and tested on a novel star field dataset consisting of data captured by the Sloan Digital Sky Survey (SDSS). The dataset is meant to simulate the expected data produced by the 6U satellite. The compression step implements GZip, RICE or HCOMPRESS compression, which are standards for astronomical data. Preliminary testing on the proposed CNN model results in a validation classification accuracy of 100% on the star field dataset, with compression ratios of 3.99, 5.16 and 5.43 for GZip, RICE and HCOMPRESS that were achieved on tested FITS image data.

Many CubeSat development program has been conducted by college and university students after first launch of CubeSats in 2003. In general, CubeSat development requires to practice systems engineering including satellite testing and project management while learning the process of manufacturing that combines elemental technologies such as mechanical engineering, electrical and electronic engineering, and information and communication engineering. Although the most of facilitators of student CubeSat project usually appreciate high educational effect for participating students, their quantitative evaluation methods for the skills acquired by students through satellite development have not yet been established. In this paper, we propose an evaluation method for the attitudes and abilities of students participating in student satellite projects. The result of the trial shows that the proposed evaluation method potentially possible to assess the 7 perspectives defined in this study.

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.

Watari et al. (Space Weather, 2009, 7) found that the geomagnetically induced current (GIC) in Hokkaido, Japan (35.7° geomagnetic latitude (GML)), is well correlated with the y-component magnetic field (By ) (correlation coefficients >0.8) and poorly correlated with Bx,z and dBx,y, z/dt. The linear correlation with By would help predict the GIC, if we have capabilities of reproducing the magnetosphere–ionosphere currents during space weather disturbances. To validate the linear correlation with By for any periods (T) of disturbances, we made correlation analyses for the geomagnetic sudden commencements and pulsations (T = 1–10 min), quasi-periodic DP2 fluctuations (30 min), substorm positive
bays (60 min), geomagnetic storms (1–20 h), and quiet-time diurnal variations (8 h). The linear correlation is found to be valid for short periods (cc > 0.8 for T < 1 h) but not for long periods (cc < 0.3 for T > 6 h). To reproduce the GIC with any periods, we constructed one-layer model with uniform conductor and calculated the electric field (IEF) induced by By using the convolution of dBy /dt and the step response of the conductor. The IEF is found to be correlated with the GIC for long periods (cc > 0.9), while the GIC-By correlation remains
better for short periods. To improve the model, we constructed a two-layer model with highly conductive upper and less conductive lower layers. The IEF is shown to reproduce the GIC with cc > 0.9 for periods ranging from 1 min to 24 h. The model is applied to the
GIC measured at lower latitudes in Japan (25.3° GML) with strong By dependence. The mechanism of the strong By dependence of the GIC remains an issue, but a possible mechanism for the daytime GIC is due to the zeroth-order transverse magnetic (TM0) mode in the Earth-ionosphere waveguide, by which the ionospheric currents are transmitted from the polar to equatorial ionosphere.

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.</p>

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.

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.

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.

<p>Disturbances in space environment around the Earth (Geospace disturbances), which are driven by the solar activities, are causes of spacecraft anomalies, radiation hazards of astronauts and aircrews on polar route, problem of navigations and HF communications, and induction current in long-line power cables. To mitigate the risk of geospace disturbances, improvement of operational space weather forecast with high precision based on numerical forecast scheme would be important. However, the poor observation points in geospace prevent us to introduce numerical forecast scheme with data assimilation technique which was common in terrestrial weather forecast. To breakthrough this situation, we are planning to develop a space environment sensor package, which can contribute to safety operation of the micro satellite itself, and to realize low-cost global monitoring of space environment based on constellation of micro satellites. Space weather observations by several tens of micro satellite constellation enables us to narrow down the sensor performance of single satellite. The optimization strategy of sensor performance for further miniaturization and power saving can accelerate mountability of the package. Based on this approach, it is expected that numerical forecast scheme with data assimilation technique will be introduced for operational space weather forecast in the future.</p>

In this paper, we introduce student's experience for a conceptual design of lunar exploration mission and discuss its educational effectiveness. Through participation to the Satellite Design Contest, it is confirmed that students can acquire integrated ability of engineering subjects and that process of proposal is quite consistent with concept of the Engineering Design Education. In particular, merging of many engineering subjects and long-term group work are quite effective to cultivate student's engineering design abilities.</p>

Myanmar is the largest country by geographical area in the Association of Southeast Asian Nations (ASEAN). Its history and culture are greatly influenced by its neighbors - India and China - which represent two of the world's great civilizations and also two of the world's most populous nations. Its geographic location at the intersection of China and India makes it well positioned to resume its traditional role as a regional trading hub and a key supplier of minerals, natural gas, and agricultural products. Myanmar is currently in a transition from a centrally directed economy to a market-oriented economy, and from 60 years of conflict to peace in its border areas. In this report, we outlines current situation of, and issues within Myanmar and it's Engineering education.

Students in an advanced course are required to pass a bachelor's-degree-examination by National Institute for Academic Degrees and University Evaluation to be conferred a bachelor's degree. One and two applications from the students of Tokuyama College of Technology were rejected by the examination in 2005 and 2006, respectively, despite a careful measure by many staffs. In order to investigate a current condition of the bachelor's-degree-examination, we sent questionnaires about number of rejected student and reason for a reject to all the national college of technology and obtained 48 responses. The result suggests that the most of colleges are confused by the rejection and seeking an effective action to improve the ratio of successful applicants.
