Satellite and Terrestrial Radionavigation Systems on European Inland Waterways

Januszewski J.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2009

Vol. 3, no. 2

121--126

The usefulness for all sea users of Satellite Navigation Systems (SNS), Satellite Based Augmentation Systems (SBAS) and Automatic Identification System (AIS) is well known. The possibility, actual and future, of the utilization of all these systems on European inland waterways, GPS augmented by IALA DGPS reference stations, GPS augmented by European SBAS – EGNOS from direct Signal–in–Space (SIS) and GPS augmented by EGNOS from re–transmission over AIS, is presented in this paper. The operational systems, such as the German network IALA DGPS and DoRIS, and planned system such as GALEWAT, MARGAL, MUTIS and MARUSE are described also.

Modernization of Maritime DGPS in Poland

Dziewicki M.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2009

Vol. 3, no. 1

39--42

Some new techniques and functionality adopted for modernization of national DGPS systems by maritime administrations in Europe are presented. Any solution adopted must meet international requirements: IMO standards and IALA e-NAV Committee recommendations. The results of DGPS Re-capitalization Meeting in Gdynia 2008 are presented. Modernization and re-engineering of maritime DGPS must take into account backward compatibility with existing onboard receivers as well as future trends towards e-Navigation. Operational and legal status of the Polish DGPS network is also mentioned in this context.
