070 - Advanced MEOSAR Test Beacon Setup
The location methods used in the MEOSAR systems are sensitive to beacon motion. A lot of work has been undertaken during the past years to elaborate test means in order to evaluate the MEOSAR location performance with moving beacons (use of vehicles, drones, turn-style mechanism, beacons of opportunity). The test means used have several drawbacks: limited test time, limited speed range,…
069 - Enabling high performance PNT in lunar environment
In the context of the renewed interest in lunar exploration, the need for preparing the future user instrument for the new positioning service on the Moon has become very important, in particular for supplementing the current navigation techniques based on inertial sensors and cameras. A significant R&D effort is ongoing towards the development of dedicated lunar infrastructures for enhanced Moon…
068 - Biosensor and PNT Integration: What is feasible?
Biosensors (pioneered by C. Clark, inventor of Clark Oxygen Electrode for blood), are sensors that integrate a biological element with a physiochemical transducer to produce an electronic signal proportional to a single analyte which is then conveyed to a detector.
A wide field of applications exists: clinical (in vivo, in vitro) and non-clinical. Typical application fields are food-analyses…
067 - Precision Agriculture - High precision coordinate and alignments transfer
In future precision agriculture, it is expected that each plant (e.g. corn) will get coordinates with very high accuracy. The type of plants and their coordinates will be stored in a database with additional agricultural information. Therefore, already during the sowing process each finger of the seeder comb/seed drill has to be coordinated with high accuracy in the relevant navigation reference…
066 - Deeply Coupled GNSS Vector tracking loop robust solution for autonomous vehicles
In conventional GNSS receivers (Scalar Tracking Loop – STL), tracking is performed in several independent tracking loops that provide measurements (pseudoranges, pseudorange rates, carrier doppler) to a navigation algorithm (e.g. kalman filter) in charge of the PVT solution.
In Vector Tracking Loops (VTL), the two tasks of signal tracking and PVT estimations are combined. This allows the…
065 - eLoran antenna for handheld devices
Enhanced-LORAN (eLoRAN) is the latest of the low-frequency LOng-Range Navigation (LORAN) systems, and provides a PNT service for use by all modes of transport (land, maritime and aeronautic). Amongst other characteristics, e-LORAN can enhance geo‐security through its jam‐ and spoof‐resistant signal characteristics of high transmit power and low carrier frequency. Furthermore, the signal can…
064 - Block-box for an optimised GNSS spectrum monitoring network using AI
There is an abundance of GNSS receivers deployed around the world providing measurements and PNT information, which are currently combined into networks for a variety of GNSS processing and monitoring applications. However, these receivers remain vulnerable and cannot be used to isolate all sources of error on all GNSS signals and constellations due to the processed nature of the receiver output,…
063 - RIS-aided wireless localization and mapping
Propagation at radio frequency suffers from obstructions due to objects blocking Line of Sight (LOS) path between the transmitter and the receiver. To increase the probability of LOS from a sufficient number of transmitting points, PNT systems imply sufficient densification and time synchronization. In spite of all these, many blind spots continue to degrade the positioning performance.
