SBAS/EGNOS for Maritime [PDF]

Journal of Marine Science and Engineering, 2020
The Global Navigation Satellite System (GNSS) has become the primary means of obtaining Position, Navigation, and Timing (PNT) information at sea. The current capabilities of the Global Positioning System (GPS) constellation, although adequate for ocean navigation, have some shortfalls for coastal navigation: some user communities have a need for ...

Parametrization and prediction of EGNOS GIVD values

2017 International Conference on Localization and GNSS (ICL-GNSS), 2017
Global Navigation Satellite Systems (GNSS) enable positioning almost everywhere in the world under open-sky conditions. However, the GNSS-based position is not exact due to various error sources. Errors in range measurements caused by the ionospheric delay are the largest error source in positioning with consumer grade receivers.

Performances of EGNOS network time: An update

2013 Joint European Frequency and Time Forum & International Frequency Control Symposium (EFTF/IFC), 2013
EGNOS is the European Satellite Based GPS Augmentation System. It generates its own time scale (ENT) that is steered to GPS time. The time offset between ENT and UTC (actually UTC(OP)) is contained in EGNOS Message Type 12. The aim of this paper is to validate the content of this message and to present the performances of ENT with respect to UTC and ...
