    No GPS, No Problem: Exploiting Signals of Opportunity for Resilient and Accurate Autonomous Vehicle Navigation
      
    Abstract
    The steady trend towards autonomous vehicles will come with a demand for full situational awareness and extremely reliable and accurate navigation systems. With no human in the loop, the cost of navigation system failure will be severe. Reliance on GPS for navigation has become a single point of failure. The recent uptick in cyber attacks on GPS (jamming and spoofing) have exposed the vulnerability of GPS-based navigation and demonstrated the necessity for a complementary navigation system.
    This talk will present a framework for resilient and accurate autonomous vehicle navigation by exploiting ambient radio frequency (RF) signals of opportunity, which are not intended as navigation sources. In this framework, specialized vehicle-mounted radios collaboratively draw relevant positioning and timing information from ambient signals of opportunity to build and continuously refine a spatiotemporal signal landscape map of the environment within which the vehicles simultaneously localize themselves in space and time. We will present an end-to-end research approach, spanning theoretical modeling and analysis of signals of opportunity, specialized software-defined radio (SDR) design, practical navigation algorithm development, and experimental demonstration of our system on ground vehicles and unmanned aerial vehicles (UAVs).

    New Concepts and Ideas to Improve the Reliability of PNT Services
     
    Abstract
    The European Galileo system moves clear steps forward towards the completion of its space and ground segment infrastructures, after starting providing early services in 2016 and with the plan to achieve the full operational capability (FOC) in 2020. Also the user segment is rapidly expanding, with the increasing introduction of mass market chipsets fully supporting Galileo in a constantly growing number of smartphones.
    In this context a strong need for R&D activities in the field of navigation signal engineering has been identified by various Programme's stakeholders. Considering the long process required for introducing new signals and features in a system that is already deployed and finds itself in the exploitation phase, early R&D activities become essential to investigate potential evolutions and new concepts to improve the Galileo signals and services in the short, medium and long term.
    The presentation will provide some examples of recent R&D initiatives in this context. In particular, technical solutions developed in the context of the Future Navigation and Timing Evolved Signals (FUNTIMES) project will be presented. FUNTIMES is a European GNSS mission evolution study funded by the European Commission within the Horizon 2020 Framework for Research and Development. Main goals of the project was to identify, study and recommend mission evolution directions and to support the definition, design and implementation of the future generation of Galileo signals.

    Towards a Comprehensive Approach for Obtaining Resilient PNT
    Abstract
    Precise positioning and timing is becoming ever more deeply embedded into worldwide critical infrastructure. In the civil domain, numerous attacks have already been seen and the sophistication of attacks is growing. A layered defense with flexible responses provides the best hope for meeting the challenges of maintaining required navigation performance under adverse conditions. 
    No single defense or offense, no matter how good, is capable of dealing with all threats.
    A comprehensive and integrated civil policy is needed that takes into account the nature of the threats, their motivations, their likely evolution, and the costs and approaches for mitigating them. This talk explores not only the technical countermeasures available to civil users but also the legal and social engineering approaches that can militate against jamming and spoofing. The importance of penetration testing is illustrated via real-world examples (e.g. Portland) of what happens when receivers meet a threat for the first time. It is found that effective strategies for civil applications are fundamentally different from those suitable for military applications. Specific and actionable recommendations at the policy, receiver and systems level will be made.

    Perspectives of PNT Services Supported by Mega-Constellations

     
    Abstract
    Recent years have been especially rich in announcements regarding the development of so-called “Mega-Constellations” composed of several hundreds of spacecrafts, if not thousands for the most ambitious forecasts. The OneWeb constellation comprising 720 LEO-satellites, the Boeing or the SpaceX “VLEO” constellations with more than 2500 spacecrafts each are first examples for such large space systems whose list will certainly continue growing according to declarations and filings. If initially designed to provide communication services, following the path of the forerunners Iridium and Globalstar systems developed in the late 90’s, this new category of constellations could also offer other types of services. This presentation will therefore investigate how Mega-Constellations could support Position Navigation and Timing (PNT) applications.
    First, the main characteristics for such new space systems will be presented, either in terms of orbital characteristics
    (e.g. spacecraft number) or cost reduction due to a fully re-thought industrialization process. Then, focus will be given to the architectural and technological specificities of LEO-based PNT systems which could represent meaningful differentiators w.r.t. Global Navigation Satellite System (GNSSs) and enhance their attractiveness. Hence, Doppler-based positioning techniques already proven in operational space systems, such as Argos or Cospas-Sarsat, shall strongly benefit of the geometry
    (i.e. velocity) and the large density of Lines-of-Sight. By combining range and range-rate positioning techniques, the availability for instantaneous and accurate positioning will thus be enhanced. Next, the role of a LEO-based PNT system within the “GNSS landscape” will also be addressed, considering either the possible complementarity or independency of services provided by both system types.  With this respect, the case of the newly introduced Satellite Time & Location (STL) system, based on the Iridium constellation, and offering a global and resilient Timing and Position service will help supporting this discussion.
    Finally, the main architectures for LEO-PNT systems will be described with special focus on the primary and ancillary payload units, but also on the supporting ground segment infrastructures.
