“…Alternatively, this can be achieved with a range of other solutions. The most frequently applied solutions include: Kalman filter [23], data fusion from various sensors [24] or using satellite network and multi-constellation solutions [15]. Other methods that cannot be ignored include: comparative ones [11], advanced methods employing adjustment computations in coastal navigation, positioning algorithms alternative to existing ones [12] or, increasingly popular, employing neural networks.…”

This paper is the fourth in a series of publications presenting the process of installation, testing and long-term assessment of the navigational parameters of the Polish DGPS system. This series of publications intends to present – to the general public – the accomplishments of teams of Polish scientists who have been working for years to make the DGPS the main positioning system used in the Polish sea areas. A considerable part of the materials presented in this paper has never been published. The article presents changes in the position accuracy of the Polish DGPS system over 20 years. Both dynamic tests performed on vessels as well as static measurements campaigns were analysed. The publication contains selected results achieved in its installation and testing in 1995–1997 supplemented with the results of studies conducted in the years: 2006, 2010, 2014, 2017. During this period the position accuracy increased from 2–8 m (1996) to approx. 1–2 m (2010) due to three reasons: turning – off the Selective Availability (2000), technical modernization of reference stations (2010) and continuous – over many years – reducing GPS signal-in-space pseudorange errors, which results in increased position accuracy in all GPS augmentation systems.

“…At the same time, methods of positioning improvement are applied both by such technical solutions as alternative positioning systems [Kelner, J.M. et al, 2016;Sadowski, J., Stefański, J., 2017], radar positioning [Stateczny, A. et al, 2019] and multi-GNSS (Global Navigation Satellite System) solutions [Specht, C. et al, 2019a;Yang, C. et al, 2016] using Kalman filtering [Xinchun, Z. et al, 2016].…”

The operating zone of a radio navigation system is one of its main operating features. It determines the size of a water body in which the system can be used, while guaranteeing vessels' navigation safety. The DGPS system in the LF/MF range is now the basic positioning system in coastal waters around the world, which guarantees not only metre positioning accuracy, but it is also the only one to provide navigators with signals on positioning reliability. This paper describes and summarises over twenty years of studies dealing with the operating zone of the Polish DGPS reference station network. This paper is the fifth in a series of publications whose aim was to present in detail the process of installation, testing and long-term evaluation of the navigational parameters of the Polish DGPS system, launched in 1995. This paper includes the theoretical foundations of determination of the Dziwnów and Rozewie DGPS reference station operating zones in the years 1995-2018. Moreover, it presents the measurement results for the signal levels and the results of their analyses, which determine the station operating zones. http://www.transnav.eu the International Journal on Marine Navigation and Safety of Sea Transportation Volume 13 Number 3
