After a quick overview of the new institute, the following projects are presented:

• COMPASSO: COMPASSO is a DLR project to test optical technologies on the Bartolomeo platform attached to the International Space Station (ISS), and to compare their performance with existing systems. In its original conception, it included an optical clock as well as a laser terminal for time and frequency transfer. A small summary is given about the current state of the project, the difficulties encountered and the lessons to be learned from this.
• Qlock: Precise and stable laser sources are an important pre-requisite for many quantum systems and for the detection of quantum effects. In the Qlock project, multiple approaches for such a stabilized laser setup are investigated. Here we present our progress in the work package using cryogenically cooled fiber resonators as frequency references aim to surpass the fundamental noise limits of state-of-the-art systems.
• QYRO: The QYRO project aims to elevate the promising gyroscope technology based on NMR (nuclear magnetic resonance) to TRL7 by building a prototype and demonstrating it on a LEO Cubesat mission. Additionally, the GALANT (Galileo Antenna) payload will utilize a GNSS antenna array in order to demonstrate the finding, and active suppression, of jammed or spoofed GNSS signals on Earth.
