The satellite training kit - DemoSat is a tool for space education and demonstration as part of the capacity building program on space engineering initiated by University of Tokyo and Institute of Technology of Cambodia. It can be used in both high school and university curriculum to introduce the functionality of the satellite and provide the basic engineering knowledge such as electronics, microcontroller programming. Moreover, it can also be used as the first step training about satellite before participating in a real satellite project.

The DemoSat satellite training kit can provide a low-cost, effective learning opportunity for students to experience space engineering. The DemoSat hardware is built using components that can be bought, manufactured and assembled locally in Cambodia which reduce the barrier for educator in Cambodia to use the training tools to train students.

Design of DemoSat

The configuration chosen for DemoSat is 1U. In addition, DemoSat has three critical components.

An Electrical Power Subsystem (EPS), consists of solar cells, a battery and a power bus, responsible for supplying electrical power to the onboard components.

An Onboard Computer (OBC) responsible for handling various tasks and functionalities

A radio transceiver (COMM) responsible for uploading command or downloading data.

The DemoSat also equipped with many sensors (camera, GPS, 9-axis Inertial Measurement Unit (IMU) sensor and temperature sensor) as an experiment device for testing data communication between satellite and ground station.
