Currently GNSS Systems provide services for instantaneous absolute positioning accuracy of a few meters, assuming no local obstructions above 5-10 degrees elevation, based on the navigation signals broadcast by a MEO constellation.
Deimos
The aim of the LIFELINE project was to perform a feasibility study of a Relativistic Positioning System. Nowadays, all GNSS in operation are based on Newtonian physics and rely on global reference frames fixed to Earth. Relativistic effects are treated as deviations that need to be corrected. A practical RPS would consist, for example, in a constellation of satellites, each one broadcasting not only its General Relativity coordinates (proper times or other observables) at emission but also the coordinates that it receives from the other satellites.
GMV
The MAGS project focused on developing a Maritime Adaptive GNSS Safety Concept to support mariners, particularly within the vicinity of ports.
DLR
This project was intended to contribute to the implementation of the e-navigation concept (as defined by IMO, Ref. 2.2.6), with primary focus on the navigation in restricted waters, such as harbours, lagoons or regions where the traffic congestion can create conditions for accidents or inefficient operations.
SATE
The basic goal of this project was to analyse how the usage of non-conventional data (i.e. 'data of opportunity') in conjunction with conventional data could help improve the estimation of parameters for weather and space weather. Conventional data it is considered to be data coming from well-known sources such as permanent GNSS receivers (e.g. receivers from IGS or EUREF networks) while non-conventional data is considered to be GNSS data from research vessels or mass-market GNSS receivers (such as smartphones or other single-frequency GNSS chipsets).

GALIST is a project that supports the traceability of food products linked to their position and the occurrence of significant events (e.g. labelling, packaging, shipping). The system is based on an innovative concept that uses GNSS combined with ADSB data, which is provided by airplanes. The GALIST project uses, in fact, a double-certification approach – based on a proprietary algorithm – to keep track of products.
Origosat
Implementation of the European Train Control System (ETCS) Level 2 requires that a huge amount of physical balises (known as Eurobalises), used to determine each train’s position and direction of motion, be deployed in order to support safe operation of high-speed / high-frequency train services all along the European railway infrastructure. The associated costs are substantial, which motivates the investigation of cheaper technologies.
GMV
Indonesia is periodically affected by severe volcano eruptions and earthquakes, which are geologically coupled to the convergence of the Australian tectonic plate beneath the Sunda Plate.
ISSIA
The main goal of GEROS-ISS is to demonstrate the capabilities of GNSS remote sensing to derive geophysical parameters of ocean, ice and land surfaces, which are associated with geophysical research with special focus on relevant climate change phenomena.

The ERICA team set up an ad-hoc measurement campaign (March-October 2015) carried on with contribution of local experts in Indonesia and Vietnam, who conducted the data collection with ground-based instruments deployed in the footprints of EIA and EIT. The set of instruments included scintillation and Total Electron Content (TEC) monitors, magnetometers, and ionosondes. Collected data comprehend raw and processed data from GNSS scintillation monitors and variation of the components of the geomagnetic field.
