The GOACE (Ground Optical Atomic Clock for Evaluation) project aims to deliver an optical atomic clock for evaluation by the European Space Agency. Developed by Rolex Quantum and CSEM, the clock employs an optical transition in Rubidium to achieve outstanding long‐term frequency stability with competitive SWaP, and low‐maintenance. The clock will undergo a full year of continuous testing at ESTEC to confirm its robustness and suitability for future needs in navigation, telecommunications, deep‐space missions, and timekeeping applications. This evaluation represents a major step toward bringing a reliable, high‐performance optical clock to the commercial market.
