104 - AI for Anomaly Detection in Multi-Sensor PNT
There is currently considerable research effort being devoted to the development of multi-sensor PNT approaches which promise greater resilience and potentially greater accuracy than GNSS alone. New sensors are also being developed which have less well understood characteristics and vulnerabilities. These include quantum inertial sensors and quantum gravimeters and magnetometers. For such complex…
103 - Precise and Stable Navigation with Quantum Accelerometer
Navigation systems that rely on Inertial Sensors are prone to drift and inaccuracies over time, affecting their accuracy, reliability, and autonomy, particularly in challenging scenarios where GNSS signals and/or external reference points availability is limited or strongly impacted.
Quantum accelerometers enable high-precision navigation with long autonomy, effective fault detection in case of…
102 - Quantum receiver for navigation applications
Recently, a wide range of experimental quantum techniques have been demonstrated in communications and sensing fields. Atom-based quantum techniques are emerging as a completely new and promising tool for advanced communications. Accurate radio-frequency (RF) electromagnetic field sensing in free-space plays a fundamental role in wireless communication, and Rydberg atoms are remarkable quantum…
101 - Underwater and underground navigation using Muons
When cosmic rays reach the upper part of the Earth’s atmosphere, several particles are created, including muons. Muons, elementary particles with the same charge of the electron but with bigger mass, can travel through any kind of material, including water and rock. A muon detector can be very small and very low cost (~ $100). Muons can be used for navigation using Reference Detectors (to…
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…
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…
079 - Reduced size Antenna for Earth Pulsar navigation
Pulsar are rapidly rotating neutron stars emitting beams of radiation periodically, some with very high stability.
Since every pulsar has a different frequency, they can be used in a navigation system like beacons, and in timing (see EL1-006).
Emission occurs in all spectrum (infrared, visible, RF, X-ray). For space navigation, detectors in X-ray are preferred for their size, but detectors…
