Mono-Nikko

Mono-Nikko [Dainikko Engineering]

Mono-Nikko is a 3U CubeSat developed by Dainikko Engineering Co., Ltd. (Japan) to demonstrate an intelligent battery anomaly detection system for ultra-small spacecraft. The satellite’s mission focuses on on-orbit validation of a smart power supply unit capable of monitoring battery health and detecting degradation or faults in real time.

The mission objective is to acquire detailed status data from onboard batteries and process this data to identify early signs of performance decline or abnormal behavior. By enabling in-orbit diagnostics rather than relying solely on pre-launch testing or ground-based assumptions, the system aims to improve reliability and operational safety for small satellite missions, where power subsystem failures are a leading risk factor.

The spacecraft is proposed by Dainikko Engineering Co., Ltd., which is developing the intelligent power unit integrating sensing, telemetry acquisition, and onboard data analysis functions. The system is designed to be compact and adaptable for CubeSat-class platforms, emphasizing low power consumption and autonomous operation. The payload demonstrates embedded algorithms for anomaly detection, likely incorporating threshold-based monitoring and potentially more advanced diagnostic logic tailored to battery performance characteristics in space environments.
