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.

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.

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.

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.
