ONGOING

CyborgLOC (Adaptive multi-sensors solution for Indoor/Outdoor geolocation)

The CyborgLOC project aims at the pre-industrial production of a multi-sensor adaptive solution for nomadic Indoor Outdoor geolocation. CyborgLOC relies on: a) the state of the art achieved by the IFSTTAR laboratory in inertial navigation (between 0.35% and 2% deviation over one kilometer), b) on Deep Learning methods And Big Data to integrate the real-time recognition of human body movements and subtract them in the trajectory calculations of the barycenter, c) on the expertise of the miniaturized microsystems of geo-location with energy harvesting of SGME as well as its mastery of sensors D) on the first prototypes of SGME for an Indoor / Outdoor Geolocation system based on the work of fusion and scheduling of data and calculations. The consortium brings together four major complementary domains to solve the challenges of the challenge: a) Inertial navigation, porting and transformation on the CyborgLOC platform of IFSTTAR's very advanced algorithms, b) Robotics, integration of algorithms and knowledge of Elter for Scheduling and behavior responsive to the environment and situation (including human body movements), c) Microsystems, miniaturization and integration of electronic microsystems of SGME (Bageo), with a search for energy saving Up to energy harvesting. These four major domains finally meet around a common theme: an adaptive geolocation system, focusing on movement and environment recognition based on deep learning algorithms for scheduling.

European GNSS Raw Measurements Task Force on Android Device

Since the opening of access to GNSS raw measurements on Android (Nougat version and higher), the GSA has launched the GNSS raw measurements working group to pool the work of the main navigation and positioning experts and to stimulate innovation around this new functionality. GEOLOC joined the Task Force as soon as it was created in June 2017.

This group aims to share knowledge and expertise on Android raw measurements and their use, including high-precision positioning techniques. The Task Force includes GNSS experts, scientists and GNSS market players, and promotes the wider use of these raw measurements.

New smartphones, starting with Android 7.0, allow developers of smartphone applications direct access to GNSS raw measurements. This is a unique opportunity to access not only pseudo-distance, Doppler and carrier phase measurements, but also to propose new strategies for calculating position, velocity and time (PVT).

GEOLOC has developed a first application called GeolocPVT under Android whose open-source codes and documentation are available on this site.

eMAPs

eMAPs consortium proposes to develop a disruptive Localisation Based Service (LBS) through its Galileo-based project eMAPs to tackle the foreseen and expected smart city and autonomous car challenges. The proposed hardware and software developments of eMAPs aim at providing future solutions such as smart navigation for connected car users, real time fleet management for city public transport and infrastructure maintenance monitoring for city planner. By developing an innovative, low-cost, compact, high performance premium receiver, eMAPs will provide a targeted 30cm vehicle’s 2D position accuracy (95%) and high definition urban maps which will benefit to all smart cities stakeholder groups: the travellers, the public transport operators and the urban authorities. The final product of eMAPs will be a platform which will hybridize data generated by a multi-frequency multi-constellation GNSS receiver, an IMU and cameras.

 

Standardization 

François Peyret and Miguel Ortiz contribute to a European standardisation group (CEN-CENELEC/TC5/WG1) on the topic of definition of performances for GNSS-based positioning terminals used in road transport and field test procedures for assessing them. F. Peyret is chairing too the French mirror group, under the responsibility of BNAE (Bureau National de l’Air et de l’Espace).

The laboratory collaborates also tightly with the ETSI group (TC SES/SCN) working on the topic, on the laboratory testing aspects, through its participation to the European projects SAGITER and ESCAPE and the liaison between CEN and ETSI on the topic of GNSS receivers performances.

The CEN group has programmed the development of 3 European standards between June 2013 and February 2016.

Etoiles Montantes

The project financed by the Pays de Loire Region is part of the preparation of an application for funding from the ERC (European Research Council), whose calls for projects are extremely competitive. It is also dedicated to the organization of the International Conference on Indoor Geolocation Solutions held in Nantes. This regional support enables Valérie Renaudin to lead both the direction of the laboratory and the preparation of the Gait4Nav research project submitted to the ERC Starting Grant in 2018.

HAPPYHAND

The HAPPYHAND2 project is a 4-year project financed by the French inter-ministerial fund FUI, in which GExpertise Conseil and Ocentis, the GEOLOC and LOUSTIC-Université Rennes 2 laboratories participate. It began on 29 September 2015.

The project aims at improving the mobility of people with temporary (or permanent) mobility difficulties, without using a vehicle thanks to

  • the mapping of urban space and its obstacles,
  • calculating routes according to disability profile and
  • real time navigation assistance on connected object.

The construction of the map is performed with an authorized instrumented vehicle (VRA) and the outcome is used to compute customized itineraries. A mobility aiding tool assist the user thanks to a precise geolocation and a telematic assistance service. The automatic feedback of behavioral alerts offers other services starting from automatic alerts up to onsite intervention in the event of a problem. The services will be enriched by the acquisition of data with the VAR but also by the customers in a crowdsourcing way.

This project is supported by laboratory cities (Nantes, Rennes). Associations on mobility and disability have also expressed interest. This commitment of third parties will benefit the experimentation that it proposes, or even a large scale distribution of the products and services resulting from the project.

ESCAPE (European Safety Critical Applications Positioning Engine)

The European Safety Critical Applications Positioning Engine (ESCAPE)  is a 3 years project designed to fullfil requirements of Autonomous Vehicles exploiting E-GNSS differentiator. Title It is funded by the European GNSS Agency (GSA) under the European Union’s Fundamental Elements research and development programme.

With connected vehicles and autonomous driving vehicles being the most relevant trend in the automotive sector there is a clear need to provide accurate and reliable positioning information for safety-critical applications. Within the context of road transportation, safety-critical applications are defined as those that possess the potential to, directly or indirectly, avoid causing harm to humans, destroying the vehicle or damaging external property or the environment. Autonomous driving, advanced driver-assistance systems (ADAS) and dangerous goods transportation are all included in this group.

The traditional way of providing the required accurate and reliable positioning information is to make use of multiple sources of sensor data. The problem with this approach is that it requires the use of such sophisticated equipment as radar/lidar-based sensor and cameras, which tend to be expensive. Furthermore, as this equipment is not specifically designed for use with automotive consumer applications, it is not fully suitable to provide reliable positioning information.

European Safety Critical Applications Positioning Engine – ESCAPE project aims to overcome these multiple challenges by developing a dedicated, reliable and accurate engine, specifically designed for automotive safety-critical applications.

The GNSS receiver in the ESCAPE engine will feature multi-constellation, multi-frequency capabilities and will be enabled to receive and process the upcoming Galileo OS authenticated signals, which is one of the key differentiators of the European GNSS, expected to be broadcast starting form 2018.

COST Action SaPPART (Satellite Positioning Performance Assessment for Road Transport) 

This Action is a network of European scientists and industrial stakeholders who have decided to collaborate on the topic of performance assessment of the GNSS-based terminals used in road transport or personal mobility applications.

The Action, chaired by Ifsttar (François Peyret), will take place from November 2013 to November 2017. The network gathers presently 13 European countries but remains open to other participants, according to the COST rules.

Main objective of the Action

Set up a European Framework for the definition of the service levels for the positioning terminals and has programmed the output of 3 paper deliverables as well as a data base, and the organization of numerous knowledge dissemination events such as seminars, conferences, summer schools, etc.

Inturb (Integrity in urban environment) 

This research project funded by the DGITM (Directorate General of Infrastructure, Transport and Maritime Affairs) aims at improving the accuracy of GPS in cities. Finally, we also propose a confidence indicator that guarantees this accuracy. 

Using knowledge of the buildings (IGN data) surrounding the GPS receiver to detect and correct satellite measurements disturbed by occultation and reflection on the walls..

French Ecotax System 

In 2009, GEOLOC has been involved in the assessment of the first embedded system proposed by all the candidates. Expertise has focused on the study of the precision of position delivered by each of  the GNSS modules and the performance of the algorithm responsible for the detection of the charging points. In 2012, IFSTTAR was government appointed “homologation organization” for the whole project. This task is carried out by GEOLOC.
