“…The COMPASSO mission (Schmidt 2022;Schmidt 2023) is a DLR-funded in-orbit verification mission with the goal of demonstrating the capabilities of high-performance quantum optical technologies in space, specifically on the ArgUS multi-payload adapter of the BARTOLOMEO platform (Airbus 2022) on the International Space Station (ISS). It is led by the Galileo Competence Center of the German Aerospace Center (DLR-GK) working in close collaboration with the DLR Institutes and industry partners.…”

One of the limiting factors for GNSS geolocation capabilities is the clock technology deployed on the satellites and the knowledge of the satellite position. Consequently, there are numerous ongoing efforts to improve the stability of space-deployable clocks for next-generation GNSS. The COMPASSO mission is a German Aerospace Center (DLR) project to demonstrate high-performance quantum optical technologies in space with two laser-based absolute frequency references, a frequency comb and a laser communication and ranging terminal establishing a link with the ground station located in Oberpfaffenhofen, Germany. A successful mission will strongly improve the timing stability of space-deployable clocks, demonstrate time transfer between different clocks and allow for ranging in the mm-range. Thus, the technology is a strong candidate for future GNSS satellite clocks and offers possibilities for novel satellite system architectures and can improve the performance of scientific instruments as well. The COMPASSO payload will be delivered to the international space station in 2025 for a mission time of 2 years. In this article, we will highlight the key systems and functionalities of COMPASSO, with the focus set to the absolute frequency references.
