Opis:
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.

Opis:
Nowadays there are two world wide satellite navigation systems - American GPS and Russian GLONASS. Distribution (in per cent) and comparison (in per cent) of GDOP (Geometric Dilution Of Precision) coefficient values for different number of operational satellites for the observer at different latitude for different masking elevation angle for both systems are demonstrated in this paper.

21st century challenges
Opis:
For nearly the entire post-World War II period, naval and air navigation relied primarily on ground-based radionavigation systems. However, the spontaneous development of satellite systems gradually led to their disappearance. They are currently used partly in air operations and marginally in maritime navigation in some areas around Asia, in Russia and in the Middle East. However, at the beginning of the 21st century, the threat of effective interference with satellite systems began to be raised, which led to an increased interest in restoring or upgrading ground-based systems as backup systems in the Western world. In this context, the approach of Russia is interesting, as it is associated with the vast majority of deliberate GPS interference. There are reports in the world literature that various ground-based radionavigation systems operating in Russia are still observed. The article analyses, on the basis of the few available sources, information on the ALFA system, about which the least is known, and there are many indications that it is ready for use.

Opis:
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.
