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…
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…
