Infield Agriculture GNSS Assessment Showing EGNOS Benefits

2020 European Navigation Conference (ENC), 2020
This article aims at presenting EGNOS (European Geostationary Navigation Overlay Service) performance computed by a GNSS receiver on board of an agriculture tractor equipped with Topcon auto-steering system where farmer planted pistachios trees in a large field within Avila province, Spain.

Has EGNOS its own place in maritime navigation?

2015 International Association of Institutes of Navigation World Congress (IAIN), 2015
GNSS (in fact it usually means GPS) is at the moment the fundamental means of positioning for any variants of navigation. However some attributes of it can be not sufficient for every users or in some tasks, so there are many cases when this system needs support.

Qualification of EGNOS for Routine Operation

2003
EGNOS is nearly ready to start providing a pre-operational Signal in Space (SIS), based on functionally qualified elements. This is the first step before reaching the complete qualification in terms of functionality and performance expected during the first half of 2004.

Performance Evaluation of EGNOS in Challenging Environments

Journal of Global Positioning Systems, 2012
Space-based augmentation systems (SBAS), such as EGNOS, are largely used to complement GPS for accurate and reliable positioning, which is required by rapidly growing location-based services (LBS). However, it is challenging to use EGNOS in the environments including urban areas and marginal area of the monitoring networks, where many LBS are delivered.

Reliability Assessment of Supporting Satellite System EGNOS

2013
The paper presents the issues related to satellite navigation systems which can be supported by the EGNOS system. It provides basic information on the structure and operation of these systems, especially the EGNOS system. This enabled an analysis in terms of reliability of both the satellite navigation systems, as well as EGNOS.

WAAS/EGNOS-ready 2-chip GPS chipset

Fifth International Conference on Satellite Systems for Mobile Communications and Navigation, 1996
The relentless climb in GPS volumes, and associated fall in prices, especially in the automotive market, mean that the OEM card or module is too expensive for the equipment builder to purchase, but gives inadequate profit margin for the OEM card supplier. Both the GPS company and the car electronics company need to reduce their costs.
