ESA project for monitoring the GNSS environment as part of real-life maritime navigation services and aimed to develop new models and methods for mitigation against errors in positioning.
Maritime transport, including the inland waterway navigation, has a very important role in Europe, enabling trade and contacts between the European countries. Furthermore, it provides the main vehicle (almost 90%) for European imports and exports to the rest of the world and more than 400 million passengers embark and disembark in European ports.
”Multipath & Interference Error Mitigation Techniques for Future Maritime e-NAV Services” (MARGOT), was the first project for the European Space Agency implemented by our company and the consortium of international partners we coordinated. The project was included in ESA’s NAVISP Element I programme and it was developed by RISE, with the Romanian Space Agency, GMV, Joanneum Research and GeoEcoMar as partners.
MARGOT was focused on monitoring the GNSS environment in real life maritime navigation services, to develop models and methods for mitigation against errors in positioning. With almost 2800 hours of data collected in different maritime and fluvial navigation environments and an in-depth analysis of the local errors that impacted the GNSS measurements, the project provided conclusions for local error modelling and recommendations for future maritime regulations.
Project main objectives:
- analyse L-band interference in vicinity of port entrances and inside ports.
- determine over-bounding multipath and interference error models for open-waters (ocean, sea), coastal, inland waterways, port entrance and port operations;
- determine simple and applicable mitigation methodologies for multipath and interference impact minimization involving antenna siting and supporting L-band multipath channel models;
- determine L-band multipath channel models for open-waters (ocean, sea), coastal, and port entrance operations;
- analyse the feasibility of developing L-band multipath channel models for inner-waterways and port operations.
