Enabling Ultra-High Accuracy Positioning in Challenging Environment
The need for high accuracy PNT in challenging environments has become obvious and, henceforth, mandatory for many applications. Currently, an accuracy target of 1 m in an urban environment seems a realistic achievement with multi-GNSS PPP or RTK capabilities. A significant R&D effort is ongoing to reach this target in operational products, using carrier phase positioning (PPP and RTK) and European…

Precise Relative Positioning in MEO to support Science Missions
Precise relative positioning in MEO (Medium Earth Orbit, at altitudes ranging between 2,000 and 36,000 km) exploiting GNSS is a subject that has been little explored while having high potential for enabling an interesting set of applications based on space-to-space interferometry.
Establishing accurate inter-satellite baselines based on GNSS measurements would open the door to new missions at…

Low-cost multi-frequency multi-constellation GNSS antenna for CubeSats
Satellites flying in LEO are relying more and more on Precise Orbit Determination (POD) through GNSS and in particular the computation of real time on-board POD with accuracy at centimetre level.
Receivers for in-orbit demonstration of Precise Point Positioning (PPP) currently under development under NAVISP (NAVISP-EL1-009: ‘Space GNSS Receiver for Un-Orbit Demonstration of PPP’) and the…

Integrity Monitoring and Prediction Concept for Autonomous Car Resilience and Safety
Autonomous driving is seen by many as a coming technology disruption that will have profound impacts on industry, society and the economy. One of the great hopes of autonomous driving proponents is the realisation of huge safety improvements. According to the World Health Organization, road accidents account for 3,400 deaths every day around the world. This is more deaths than those caused, 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…

Low-RF Fast Deployable Systems for Emergencies in Difficult Environments
There exist a number of applications requiring reliable and accurate navigation services in environments difficult to access where available commercial products struggle to satisfy the variety of user demands. Such applications include very deep indoor applications, for which navigation accuracy and timely operations are critical to users, as for example in emergencies or underwater/urban-canyon…

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…

Quantum-based sensing for PNT
The exploitation of quantum physics has already enabled revolutionary technical applications and industries of enormous economic scale. The semiconductor industry alone is currently a €500 billion market, giving rise to industries on an even larger scale (smartphones, computing, software, etc.).
Quantum physics is now again set to radically change several industries, including…
Trusted Radionavigation via Two-Way Ranging
Wireless positioning systems based on passive ranging, as used in GNSS today, are very attractive and represent the most pragmatic and cost-beneficial solution for worldwide positioning in benign, secured environments; however, this may no longer be a one-size-fits-all solution for modern radionavigation usage as the need for complementary solutions offering adaptability, reliability and trust is…

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…
