FIRST-TF 2025 annual meeting & workshop on “Application of Time-Frequency technologies to defense and space industries”
Slides presented at those events are now available at this page
Call for Abstracts: ITM/PTTI 2026
Abstract Deadline is October 3, 2025
Submit your abstract today for the ITM/PTTI 2026 conference. The ION International Technical Meeting (ITM) features a technical program related to positioning, navigation and timing and includes the ION Fellows and Annual Awards presentations. The meeting will take place in Anaheim, California, January 26-29, 2026, and will be co-located with the Precise Time and Time Interval Systems and Applications Meeting (PTTI).
Two Technical Events for the Price of One
ITM is the ION’s winter meeting with peer-reviewed technical papers related to positioning, navigation, and timing and includes the ION Fellows and Annual Awards presentations.
PTTI is the technical conference designed to disseminate and coordinate PTTI information at the user level; review present and future PTTI requirements; inform government and industry engineers, technicians and managers of precise time and frequency technology and its problems; and provide an opportunity for an active exchange of new technology associated with PTTI.
Registration will open in Fall of 2025.

Call for Abstracts – EPSC-DPS 2025 Session on “Advanced Methods for Space and Planetary Navigation: Quantum Sensors and Emerging Technologies”
Late abstracts are possible until May 21 max
directly with the session organizers
https://www.epsc-dps2025.eu/programme/how-to-submit.html –> Late abstract submissions
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.

Conference: De l’astronomie aux horloges atomiques, une fabuleuse épopée de la mesure du temps – May 15th 2025, 6pm – LNE – Paris
Conference on measurements and time
The LNE is continuing its “Les mesures et…” series of conferences, with the fifth “Les mesures et le temps : quel futur ?” conference on May 15, 2025. “.
De l’astronomie aux horloges atomiques, une fabuleuse épopée de la mesure du temps
[conference in French]
Since ancient Egypt, humans have deployed remarkable techniques and strategies to push back the limits of precision in time measurement.
In this lecture, you’ll discover how, in the mid-twentieth century, quantum physics supplanted astronomy to produce time measurements with atomic clocks whose current accuracies reach 18 digits, corresponding to a drift of just one second over 15 billion years. This precision is not ultimate, and will have to be further improved to meet the major challenges of science and society, with a necessary change in the definition of the unit of time, the second, planned for the next decade.
Program and speakers
Moderator:
Maguelonne Chambon (LNE Research Director)
Speakers :
Noël Dimarcq (Research Director, CNRS)
