• Inexpensive Helical Antenna for Global Navigation Satellite Systems

  Publikacja

  • Ł. Sorokosz
  • W. Zieniutycz

  - Rok 2010

  Zaprezentowane zostały wyniki badań teoretycznych oraz eksperymentalnych niskobudżetowej anteny na pasmo L. Wyjściowa geometria struktury została obliczona na podstawie ogólnych wzorów. Efekt przesunięcia częstotliwości wywołany przez użycie rdzenia PU został również uwzględniony. Równolegle przeprowadzono badania wrażliwości parametrów anteny na proces produkcji. Zaprojektowano i wykonano układ dopasowania impedancyjnego. W paśmie...

  Each year, global navigation satellite systems (GNSS) improve their accuracy, availability, continuity, integrity, and reliability. Due to these continual improvements, the systems are increasingly used in various modes of transport, including rail transport, the subject of this publication. GNSS are used for rail passenger information, rail traffic management, and rail traffic control. These applications differ in the positioning...

  • K. Gierłowski
  • J. Rak
  • J. Woźniak
  • K. Nowicki

  - IEEE Access - Rok 2021

  The development of broadband network access technologies available to users on land has triggered a rapid expansion of a diverse range of services provided by terrestrial networks. However, due to limitations of digital communication technologies in the off-shore area, the maritime ICT systems evolution so far has not followed that trend. Despite the e-navigation initiative defining the set of Maritime Services, the progress in...

• Survey of Radio Navigation Systems

  Publikacja

  • P. Falkowski-Gilski
  • J. Stefański

  - International Journal of Electronics and Telecommunications - Rok 2015

  At present, there is a growing demand for radio navigation systems, ranging from pedestrian navigation to consumer behavior analysis. These systems have been successfully used in many applications and have become very popular in recent years. In this paper we present a review of selected wireless positioning solutions operating in both indoor and outdoor environments. We describe different positioning techniques, methods, systems,...

• Performance Analysis and Quantification of BeiDou Navigation Satellite System (BDS-3)

  Publikacja

  • A. M. Soomar

  - Rok 2023

  Positioning, Navigation, and Timing (PNT) information play a vital role in everyday life of common persons. People greatly rely on Global Navigation Satellite System (GNSS)-enabled applications for navigation to reach their desired destination. However, GNSS navigation performance is highly degraded in urban environments due to the high probability of signal interruption, multipath (MP), and/or non-line-of-sight (NLOS) signal...

• Use of Data from Satellite Navigation System in Operational and Strategic Management of Transport in Cities

  Publikacja

  • J. Oskarbski
  • K. Birr
  • K. Żarski

  - Journal of KONBiN - Rok 2019

  The article presents the possibilities of using data from the Global Positioning System for the development of traffic models and examples of use this data in the transport management. Traffic models are useful tools in planning and evaluation of transport solutions, but also can be used for current, operational transport management.
