The Taiwan-Russia collaborative satellite development project was initiated in Dec. 2005. The objective of this project was to develop and perform a science mission on a microsatellite, named ESEMS (Experimental Scientific-Education Micro-Satellite), among the team members of National Cheng Kung University (NCKU), National Central University (NCU) and Lomonosov Moscow State University.
In this project, the main tasks of National Cheng Kung University include hardware/software development of a space-borne computer, setup of a ground station, test-bed of a satellite engineering model, project coordination and interface integration. The major tasks of National Central University (NCU) include two scientific payloads, magneto-resistance magnetometers and electron temperature probe developed by their in-house team.
The scientific objective is designed to calibrate data recorded in the 3-6 months period and to derive the magnetic field based on model corrections and the electron temperature measurements in the ionosphere. The derived data is used to observe variations of the magnetic field and the electron temperature in the ionosphere associated with space weather and possibly correlated with earthquakes.
The current status of ESEMS is in its early orbit stage. In this project, to further strengthen the international cooperation, the NCKU Team will establish a task force for the ground station to receive telemetry from and transmit commands to the ESEMS satellite. The science data will be checked and calibrated by the NCU team.

    ESEMS Satellite Design
    Version A:
    A preliminary (2006 version) ESEMS design is depicted in which a gravity boom was used.

    In 2007, a three-axis stabilized configuration was developed to fulfill the requirements in attitude stabilization.

    Version C:
    In 2008, the design was further revised as high-efficiency solar cells was employed.
