Abstract

Scientists at the International Space Station have been studying space life sciences to prepare for future manned space explorations, and require experimental specimen such as rodents for mass measurement. However, it is challenging to use mass measurement systems in space owing to the errors caused by factors such as mechanical-electronic noise. Therefore, to minimize the measurement errors, we propose a new algorithm called multiple calibration, which divides the mass range and calculates the sample weight by using the correction equation of each interval. We performed tests to evaluate and compare the performance of the proposed method to that of normal methods. As a result, the measurement accuracy improved by over two times using the multiple calibration method. Furthermore, we conducted mass measurements on various samples and confirmed that our method is valid for mass measurements.
