099 - Location, Tracking and Salvage support of lost shipping containers at sea

Each year 226 Million container boxes are shipped. About 1600 boxes/year (0,002%) are lost at sea. The boxes are afloat for days to weeks before they are sinking & grounding. The reasons can be traced to top-heavy container stacks (unstable), increasing bad weather (storms) by climate change and time pressure on ship crews (higher on the supply-chains after COVID). The number of boxes lost at sea…

098 - Metrics to Assess the Performance of GNSS Authentication Schemes

All 2nd Generation GNSSs are making use of Authentication (civil signal anti-spoofing). The potential spoofing attack vectors are known: Meaconing, record and replay, fake signal generation. Different Authentication schemes (system level) will be used and applied as countermeasures in addition to user related measures. However, a gap exists in the evaluation methodology of the robustness…

097 - Use of ML techniques to optimize the adaptive beam-steering capabilities of CRPAs for GNSS user receivers

Controlled Reception Pattern Antennas (CRPAs) in GNSS receivers are known as a fundamental resource for jamming and spoofing counteraction; they are excellent for multipath mitigation too as well as NLOS signals exclusion. CRPAs in L-band impose arrays with significant dimensions (more than four antenna elements quickly reaching square-meter areas). Further improvements can be obtained if a more…

096 - Advanced visual INS for high-end handheld devices

Vision-based navigation (e.g., SLAM, visual INS), and its combination with other PNT sensors, is at the core of the positioning engine of many autonomous systems; the prospects for further improvement for autonomous vehicles has been studied in various NAVISP activities (e.g. EL1-026). Meanwhile, powerful vision and graphical processing units are introduced in handheld devices in combination with…

095 - Exploitation of Geo-spatial Data for Automated Vehicles

The provision of ubiquitous, high-quality, positioning, navigation, and timing information, and the full situation awareness of the environment, belong to the main challenges for Connected, Cooperative and Automated Vehicles (CCAV), that need to be countered in the future.    Geo-spatial datasets capturing the topographic surface of the Earth and its overlying features, such as building…

094 - High-accuracy formation flying technologies for future distributed space instruments

More and more advanced sensing systems implement the concepts of distributed instrumentation, in areas ranging from science to telecommunications. Typical illustrations include astronomy with optical and radio-telescopes (e.g., SKA, ALMA), underground sensing, and some implementation of massive MIMO over multiple base stations in 5G/6G networks. The opportunity of distributed instrumentation has…

093 - Enabling PPP ambiguity resolution in satellite and terrestrial frequency-varying carrier-phase signals

Carrier-phase signals constitute the key observations in Global Navigation Satellite Systems (GNSS) for precise user positioning. To fully exploit these high-precision measurements, one needs to recover the integer nature of ambiguities. The Integer Ambiguity Resolution enabled Precise Point Positioning (PPP) concept, namely PPPAR, has proven to be capable of delivering centimetre-level…

092 - Integrity in 5G Private Networks for Industry 4.0

5G private networks have been of interest to industrial applications, such as smart manufacturing, process automation, or logistics, supporting the Industry 4.0 revolution across all verticals. 5G private networks can deliver communications with very low and guaranteed latency and ultra-high reliability, previously only possible through wired solutions. Besides requiring ultra-reliable and…

091 - Proof-of-concept of SOOP with broadband satcom signals in Ku/Ka-band

The feasibility of Positioning-Navigation-Timing (PNT) using signals of opportunities from broadband satellite communications systems operating in Ku/Ka-band has been demonstrated in the US in the academic context in recent years. The next step towards potential commercial products is to prove the concept with enabling technologies representative of real-world applications (e.g., form factor,…

090 - Robust Navigation for Autonomous Driving with Low-Cost/SWaP Arrays of Antennas

The derivation of robust positioning solutions under harsh propagation conditions typical of autonomous driving applications remains an open problem in GNSS. The application of Multiple-Input-Multiple-Output (MIMO)-GNSS-like processing approaches for robust GNSS positioning with low-cost arrays of antenna platforms has shown important benefits in the presence of obstruction, fading and multipath…
