Application the SBAS/EGNOS Corrections in UAV Positioning
Energies, 2021 The paper presents a new concept of determining the resultant position of a UAV (Unmanned Aerial Vehicle) based on individual SBAS (Satellite-Based Augmentation System) determinations from all available EGNOS (European Geostationary Navigation Overlay ...

On Egnos Monitoring in Local Conditions
Artificial Satellites, 2013 ABSTRACT Any SBAS system should deliver to the user corrections to pseudoranges as well as information about the system integrity. In theory, as soon as the system is permanently monitored by RIMS stations, it is impossible to deliver the fault information to the user. However many observations shows that accuracy of EGNOS service in the same time

Assessment of EGNOS Tropospheric Correction Model [PDF]
Journal of Navigation, 2001 Within the implementation of the European Geo-stationary Navigation Overlay System (EGNOS), a significant residual error in positioning is due to tropospheric delay effects. The EGNOS guidelines recommend that tropospheric delay is modelled using an empirical correction algorithm based on a receiver's height and estimates of meteorological ...

Local Monitoring of EGNOS Services
Annual of Navigation, 2012 Abstract Any SBAS system, as soon as it is permanently monitored by Earth stations, should deliver to the users correct information about quality of the augmented system. According to many sources of information, among them observations of authors, present accuracy of EGNOS service has accuracy about 1,5m (95%), but availability of the service is ...

, 2004 Questo articolo descrive quali sono le informazioni aggiuntive che il sistema di augmentation EGNOS fornisce. In particolare si considerano le correzioni inviate dal primo prototipo di EGNOS (European Geostationary Navigation overlay Service) e cioé l' ESTB ( Egnos System Test Bed). Per una più completa documentazione si può far riferimento a quella

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 ...

, 2016 EGNOS, the European SBAS is in principle known for its services augmenting GPS in the positioning domain as its Open Service for the accuracy (RD1) or its Safety of Life Service (RD2) for the integrity and a safe navigation. Nevertheless, an auxiliary timing service is also provided.
