Permanent research position on artificial intelligence for positioning and navigation


The University Gustave Eiffel, created on January 1, 2020 from the merger of the Ifsttar (French Institute of Transport, Planning and Network Sciences and Technologies) and the Université Paris-Est Marne-la-Vallée, is a major player in European research on cities and territories, transport and construction. It is a scientific, cultural and professional public institution (like all French universities) with an experimental status and a national presence, which makes it a unique university in France. It aims to be a major player in the field of transportation and urban research. The research laboratories of the Université Gustave Eiffel conduct both upstream and downstream research and expertise in a wide range of disciplines (mathematics and computer science, electronics, materials, chemistry, civil engineering, geosciences, social sciences, psychology, economics, management, innovation sciences, communication, ethics, history, art, literature, etc.) and in areas with a strong social impact such as transport, infrastructures, natural hazards and cities, to improve the living conditions of our fellow citizens and, in a broader sense, promote the sustainable development of our societies.

The GEOLOC laboratory brings together an international team of dynamic researchers with expertise in positioning and navigation solutions, developing innovative algorithms and devices to improve the mobility of people and vehicles. Localization, which has become widespread thanks to the use of smartphones, offers new opportunities to better support daily mobility adapted to each individual. Our research takes into account the specific needs of location-based applications and services to create algorithms adapted to new forms of mobility, responding to climate change, encouraging the sharing of means of transport, or providing better navigation aids for vulnerable people.
The positioning solutions we are looking for are ubiquitous, accurate, reliable, and secure, to support critical soft mobility applications. They also need to be certified to ensure that they are part of an economic and industrial reality that is having an impact on our society. This research is based on signals and measurements from inertial sensors, magnetometers, GNSS receivers, and cameras, as well as relevant map data. To carry out this research, the laboratory uses original equipment, such as an instrumented vehicle (VERT), connected smart devices (ULISS, PERSY) that replace a smartphone, and a multi-sensor reference solution that models human body movements in 3D. The GEOLOC laboratory is also actively involved in international scientific activities, steering international conferences and standardization groups, organizing indoor positioning competitions, and leading a new open-access scientific journal.

The GEOLOC laboratory is part of the AME ("Aménagement, Mobilité, Environnement") department and deals with the transportation and mobility of people and goods in their interaction with the built environment and the socio-technical systems on which they are based, as well as with the natural environment and the planning of urban and non-urban areas. The department is concerned with mobility, its practices and related policies, as well as the different environments with which it interacts: technical systems (infrastructures, vehicles, facilities, information systems), actor systems and ecosystems. The skills and disciplines mobilized in the AME department are diverse: human and social sciences, engineering sciences, environmental sciences. The department's research activities are based on both quantitative and qualitative approaches. The scientific project of the AME department is structured around three axes: systems of actors (institutions, operators and industries, end users), ecosystems (biodiversity, air, water), technical systems (infrastructures, vehicles, information systems).

Job description

The focus of this research opportunity is to explore artificial intelligence methods that utilize physical, spatial, and temporal navigation data to support new forms of mobility. The Research Fellow will focus on the intricacies of customizing mobility assistance systems to individual needs, evaluating the performance level of positioning/navigation systems, and assessing digital tracks and signals from wearables. Its central role is to bring the service dimension to the development of pioneering AI-based methods in the field of positioning and navigation aids. This research can be divided into several areas:

  • Interpretability of AI models
  • Development of models that are robust to change: environment, hardware, mobility profiles,
  • Adaptation of AI models to real-time constraints
  • Automation of learning on extended databases
  • Methodology for building optimized databases
  • Participation in the development of data management plans required for AI.

The Research Fellow will join the research team of the GEOLOC laboratory and participate in the supervision of research projects, in collaboration with the other laboratories of the AME department working on mobility and map data. He/She will utilize his/her expertise in dynamic positioning methods to contribute to teaching activities at the University Gustave Eiffel and collaborate with local partners to enhance the educational experience in this domain. The Research Fellow will develop new conceptual and technical expertise in the field of artificial intelligence for positioning and navigation and disseminate this knowledge through scientific animations and presentations within the AME department. He/she will work collaboratively to design and implement data management plans that facilitate the efficient collection and utilization of large datasets required for advanced AI methods.

In addition to his or her research production activity, a Research Fellow is also expected to develop, in the long term, a diversified activity in all or part of the following activities:  

  • Teaching and research training (teaching, supervision of trainees, doctoral and post-doctoral students, participation in juries and bodies or committees related to teaching)
  • Research administration and facilitation activities (team facilitation, project coordination, staff management, management of test facilities)
  • Valorisation and transfer activities (research and industrial contracts, consultancy and advisory activities, transfer of research results to the socio-economic world, contribution to public policy development, dissemination of scientific culture)
  • International activities (participation in European projects, ongoing international collaborations, contributions to the international visibility of the university)
  • Scientific outreach (membership of learned societies, editorial boards, scientific committees of institutes, conferences, recruiting committees).

Expected profile

The candidate must hold a PhD in signal/image processing, applied mathematics or computer science, or be able to prove an equivalent level, in particular for foreign candidates (publications, participation in projects, teaching).
For this position, specialization in Artificial Intelligence (or statistical learning methods) and experience in their application to one or more of the following fields are required: Geomatics, Navigation, Mobility.
The candidate's application file should highlight his/her ability to develop the activities (listed above) expected of a research Fellow.

Financed by the French Research Agency (Agence Nationale de la Recherche), this postdoctoral research fellow position will work in the framework of the project ReSilientGAIA (Reliable Positioning System for Soft Mobility Safety Enhancement with a Green AI Approach). The objective of this project is to add safety control in a new reliable positioning algorithm based on multisensory fusion for soft mobility users (pedestrian, bikes, e-scooters, etc). The sensors considered in this project include Global Navigation Satellite Systems (GNSS), Inertial Navigation System (INS), magnetometer and barometer. Our ambition is to design new approaches based on AI to build physical models that describe the signal perturbations in complex urban environments. By improving the safety and reliability of the positioning system for soft mobility, this project contributes to the mobility transition strategy toward lower carbon emissions. 



The postdoctoral fellowship will work on the following missions:

  • Vehicular AI model training for GNSS measurement anomaly detection and positioning uncertainty estimation. To do this, the existing labeled dataset will be used in priority. Potential environmental features (such as urban morphological indicators) will be considered using the 3D city model.
  • Propose an approach of automatic data augmentation and continuous learning for the pre-trained vehicle anomaly detection model.  
  • Soft mobility data labeling technique development using fisheye camera: propose a method to further evaluate and improve the accuracy of the labeling technique developed in [1], which uses image segmentation and satellite projection.   
  • Once the labeling technique is developed, a soft mobility multiple-sensor dataset will be constructed. The soft mobility considered in the project includes mainly pedestrians, bikes and e-scooters.
  • Analyze the feasibility and the possible approaches of the transfer learning between vehicle and pedestrian.
