Egnos Limitations over Central and Eastern Poland – Results of Preliminary Tests of Egnos-Eupos Integration Project [PDF]
Artificial Satellites, 2013 Abstract The problem of insufficient accuracy of EGNOS correction for the territory of Poland, located at the edge of EGNOS range is well known. The EEI PECS project (EGNOS EUPOS Integration) assumes improving the EGNOS correction by using the GPS observations from Polish ASG-EUPOS stations.

Development of the EGNOS Pseudolite System [PDF]
Journal of Global Positioning Systems, 2007 In order to access the Satellite Based Augmentation System (SBAS) service, the end user needs to have a direct line of sight to at least one of the Geostationary Earth Orbit (GEO) satellites transmitting the augmentation messages. This requirement is critical for users in environments such as city canyons, valleys and fjords since high buildings and ...
