Local Monitoring of EGNOS Services [PDF]
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 ...

, 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.

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 ...

, 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

EGNOS vertical protection level assessment
, 2003 The EGNOS Signal In Space (SIS) performance is defined in terms of accuracy, integrity, continuity of service and availability. For Civil Aviation, those four components of the performance shall fulfill ICAO requirements (particularly stringent for the integrity). EGNOS is expected to be operational by the first quarter of 2004. One of the major issues

Land Degradation &Development, Volume 34, Issue 16, Page 4823-4832, October 2023., 2023 Abstract The paper describes the transformation of the coastal landscape near former Davislaguna Lake, SE Spitsbergen. It is a comparative study which outlines the changing state of the area based on old maps, other archival materials, remote sensing data from the years 1900 to 2021, and our own fieldwork performed since 2005.

River Research and Applications, Volume 39, Issue 2, Page 266-273, February 2023., 2023 Abstract Widely available ‘fish‐finder’ echo‐sounding devices are beginning to be used in bathymetric studies to estimate geomorphic change. To date, however, there have been no applications in shallow and complex wetlands, where changes in sediment storage are notoriously dynamic in time and difficult to describe accurately in space.
