GTP-2018-NAV-PFS(2) - Future PNT System Concepts
ESA has the role of design authority for GALILEO. GALILEO is a Global Navigation Satellite System able to deliver Position, Navigation and Timing (PNT) in an autonomous way based on similar principles as GPS. GALILEO is currently under deployment and will be able to offer future Open Services, Commercial Services and Public Regulated Services; it will also contribute to the COSPAS-SARSAT Search and Rescue. GALILEO will work in a multi constellation environment in which other similar systems (GPS, GLONASS, BEIDOU, IRNSS and QZSS) are deployed or under deployment. In addition, other satellite communications systems and concepts such as Iridium, Globalstar and the mega-constellation initiatives intend to or are analysing the capability to provide PNT to complement or even replace GNSS in specific environments where GNSS turns out to be weak. Those environments comprise urban areas, outdoor-to-indoor transition and indoors. Also terrestrial cellular communications standards, such as 5G, are addressing more and more the capability to offer PNT.
Today GNSS is the baseline solution for PNT. GNSS multi-constellation is a "de facto" standard partly considered in the initial definitions of the current GNSS systems. But society demands more and more ubiquitous, accurate and reliable positioning. PNT is more and more present in wearables, internet of the things devices, personal communication devices, UAVs and cars. Therefore a growth in complementary and competing solutions to GNSS can be foreseen. The user segment also follows this trend by offering hybrid solutions where a single position processor is able to handle inputs from different front-ends, each one getting measurements from different PNT systems. Hybridisation with inertial sensors is a common practice in user equipment as well.
As GALILEO deployment progresses, ESA and the Programme Authorities are also engaged in defining the GALILEO 2nd Generation. The 2nd generation seeks the improvement in coverage, accuracy, time to fix and vulnerability of PNT services through addition of new system concepts and innovative technologies. Nevertheless, in this fast evolving PNT environment, the 2nd Generation needs to consider the full PNT landscape in order to be able to establish the correct evolution direct and requirements.
This work is carried out by the GALILEO 2nd Generation team, under the Directorate of the GALILEO Programme and Navigation-related Activities (D/NAV). The Trainee would take part of the system-level activities in support of the definition of new system concepts for the GALILEO 2nd Generation with focus on the current PNT landscape, its evolution and what the GALILEO 2nd Generation can add to the future PNT users.
- analysis of existing and prospective Satellite-based PNT systems from a service volume point of view (coverage in realistic environments, availability, accuracy) and from a user point of view (user application, high level receiver architecture, complexity and cost, power consumption and integration in user platforms, etc)
- analysis of existing and prospective terrestrial PNT systems from a service volume point of view (coverage in realistic environments, availability, accuracy) and from a user point of view
- analysis of the capabilities of PNT sensor augmentation systems (inertial units, magnetometers, cameras, ...) in combination with other PNT systems
- assessment of the synergies and weaknesses of the different PNT systems versus GNSS
- synthesis of recommendations and system-level specifications for the GALILEO 2nd Generation in order to make it fit optimally in the future PNT landscape
- the work requires the development and usage of analytical and simulation tools
