038 - Application of Machine Learning Technology for GNSS IoT Data Fusion

Recent advances in technology have contributed to the deployment of a "de-facto" large GNSS receiver array based on affordable smart devices that are easy to find in the consumer market (dual band smartphones, raw GNSS data recording, new sensors).  These devices, evolving fast with each new generation, feature an increasing number of capabilities and sensors able to collect a variety of…

035 - Machine-Learning to model GNSS systems

GNSS simulations are an important toolset supporting system engineering trade-offs and decisions. They are used to display and monitor key system performance indicators as well as study system behaviour, both through synthetic scenarios and real data replay. Industry and ESA currently use different tools to simulate GNSS systems, however often constrained to undertake only one of two different…

025 - Multi-Sensor, Multi-System for Space PNT Applications

Position uncertainty during autonomous manoeuvres such as orbit-raising/de-orbiting requires that the local knowledge during low thrust (i.e. with electric propulsion) is accurately determined. Current orbit-raising assumes semi-autonomous control assisted by GNSS, with a long time integral to measure increasing altitude and trajectory of the satellite. The use of a hybrid GNSS unit that…

Ultra-Low Power Device Positioning Concepts

There are an increasing number of IoT applications, and projections show that global Low Power Wide Area (LPWA) connections will increase by almost one order of magnitude in the next five years. Terrestrial networks are continuously targeting evolutions of the IoT markets. For example, the latest release of 3GPP standards has introduced modifications to their standard (e.g. NB-IoT) to comply with…

GNSS/non-GNSS Sensor Fusion for Resilience in High Integrity Aviation Applications

GNSS technology has demonstrated its capability to provide very good performance in Europe up to LPV 200 based on GPS L1 (single frequency, single constellation) and is expected to reach CAT I Autoland with the future DFMC mode (Dual Frequency, Multi Constellations – GPS & GAL). It is very challenging to improve this performance, more specifically the 6-second Time To Alert (TTA) that seems…

PNT using Neutrino Particles

This proposed activity represents an innovative concept to realise Positioning, Navigation and Timing using neutrino particles. At present, standard navigation approaches – including satellite navigation – rely on direct line-of-sight RF and optical communications. Neutrinos move at around the speed of light, have no electric charge and are low mass, thus showing very low interaction with…

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…
