The project MOBeFuse (Monitoring Orbital Behavior of eFusewas launched to validate the space suitability of commercial, miniaturized electronic fuses (eFuses) intended for use in the ERWIN CubeSat.

The initiative originated from an offer by the Munich-based startup OroraTech, which is building a CubeSat constellation for early global detection of wildfires. OroraTech provided the SeeSat e.V. with a 60×60 mm slot on the outside of one of their satellite platforms, which could be used for any payload. SeeSat e.V. is taking advantage of this opportunity to test the functionality and reliability of eFuses under real space conditions.

As part of the MOBeFuse mission, three different fuse circuits are being tested under orbital conditions. The recorded performance data will be correlated with environmental influences such as radiation dose and temperature in order to assess the long-term usability of the components.

With this mission, SeeSat e.V. is realizing its first hardware in orbit and contributing to the testing of commercial standard components for future satellite projects. The knowledge gained will flow directly into the development of the ERWIN CubeSat and enable a reliable, space-proven power backup strategy.
