We are pleased to invite you — on behalf of Prof. Dr.-Ing. Steffen Schön and myself — to contribute to our session at the upcoming EPSC-DPS Joint Meeting 2025, which will take place from 7–12 September 2025 in Helsinki, Finland.

Session Title: Advanced Methods for Space and Planetary Navigation: Quantum Sensors and Emerging Technologies

Session Link: https://meetingorganizer.copernicus.org/EPSC-DPS2025/session/55153

This session aims to bring together researchers working on the development and application of quantum sensors—such as quantum accelerometers, quantum gyroscopes, and optical clocks—in the context of space navigation.

In addition to quantum technologies, the session will also explore:

• The feasibility of deep-space GNSS, including recent demonstrations of GNSS signals in cis-lunar space and their potential for lunar and Mars missions.

• Hybrid navigation systems combining quantum inertial sensors, optical clocks, deep-space GNSS, and other emerging methods.

• Modern navigation techniques for planetary surface rovers, addressing autonomy, precision, and robustness.

We welcome contributions covering theoretical foundations, experimental implementations, mission concepts, and cross-disciplinary solutions.

Abstract Submission Information:

• Deadline: 7 May 2025, 13:00 CEST

• Presentation Formats: Oral, Poster, or Dissertation Talk

• Participation Options: On-site in Helsinki or Virtual

• All accepted abstracts will receive a DOI and be published in the conference proceedings.

We look forward to your submissions and to an engaging session on the future of space and planetary navigation.
