About
The NART-EPS Electric Power Subsystem (EPS) offers enhanced life cycle, depth of discharge, efficiency, and reliability compared to alternative power solutions for satellites. A key feature is its use of supercapacitors, which provide a significantly better life cycle and a robust thermal operating envelope when compared to common battery options. The system is designed with a user-friendly development environment, offering different options for both development and flight models. This flexibility allows users to efficiently develop and launch their satellites in a cost and time-effective manner. To ensure optimal performance and high reliability in orbit, all components used in the NART-EPS system are carefully selected from previous missions or have undergone thorough testing in a Thermal Vacuum (TVAC) environment.
