Resilient, Trustworthy, Ubiquitous Time Transfer

Secure and reliable time transfer is a key enabler for the next generation of services worldwide. A number of different applications such as 5G mobile broadband, mobile multimedia broadcast, power grids, terrestrial positioning services, financial operations, IoT, big data and cloud processing will require accurate, secure and reliable time information to be able to work consistently and…

High-Altitude Pseudo-Satellites for PNT

High-Altitude Pseudo-Satellites (HAPS) are airships “quasi-”stationed at a height of 20-30 km, in an altitude range where atmospheric winds are milder. HAPS are normally solar powered, unmanned, large, helium filled and semi-rigid; they can be operational for several years.  HAPS have been studied in the telecom domain (ESA GSP HAPPIEST study), where they were briefly considered…

Techniques supporting Resilience for High Integrity Train Control Applications

European Rail Traffic Management System (ERTMS) to improve operational performance and reduce the cost of the overall system. In order to ensure that an enhanced ERTMS with satellite positioning is interoperable and minimises impact on the existing system, the ERTMS supply industry has been working on the realisation of a concept using GNSS to detect virtual balises. The use of carrier phase for…

Artificial Intelligence / Machine Learning Sensor Fusion for Autonomous Vessel Navigation

Maritime transport is currently facing new challenges such as significant increases in transport volumes, more stringent environmental requirements and a shortage of seafarers in the future.  One of the many new concepts having the potential to overcome these challenges is autonomous ship navigation. In particular, the concept is expected to allow for more efficient and competitive ship…
