The Maritime LOPOS EGNOS Test Bed (MARLET)

The aim of this project was the demonstration of the European Geostationary Overlay Service (EGNOS) in the maritime environment in two domains: Hamburg port operations and in the context of the forthcoming installation of AIS transponders aboard seagoing vessels.

In particular, the following tasks were performed:

• An examination of integrity for the LOPOS-generated GPS / GLONASS correctional data
• A performance comparison between local production of correction data and use of EGNOS
• A test of the operative use of EGNOS for commercial applications in shipping
• An investigation of the suitability of EGNOS for alternative navigational solutions – namely AIS – for the intelligent and selective reduction in the amount of data to be transferred.

The MARLET project was initiated in December 2001 and was completed in December 2002.
