The main scientific aim of the UCAnFly nanosatellite is to explore the feasibility of novel magnetic measurement systems for space missions requiring tiny sensors and long-integration time, such as space-borne gravitational wave detectors mainly based on laser interferometry, but also in cold-atom precision interferometry.

Space observatories for gravitational waves, such as LISA, are equipped with dedicated on-board instrumentation capable of measuring magnetic fields with low-noise conditions at millihertz frequencies. The reason behind this is that the core scientific payload only works if the magnetic environment meets certain strict low-frequency requirements. For this purpose, a compact payload able to achieve the demanding low-frequency magnetic requirements for LISA will be developed for a 1U-CubeSat, which will make it possible to improve the technology readiness level (TRL) of the instrument.

Thus, the UCAnFly CubeSat will allow the in-flight low-frequency noise characterization of the system and make it possible to measure the capability of the instrument under harsh space environment.
