EGNOS performance in several maritime campaigns

Lacarra E., González R., Lopez-Martinez M.

Vol. 17 No. 4

855--861

This article presents the EGNOS (European Geostationary Navigation Overlay Service) performance observed along several maritime campaigns carried out in European waters with the objective to demonstrate the availability of corrections and the suitability of the accuracy to support maritime navigation. The regions selected correspond to those located in the border area of EGNOS coverage and include the following campaigns: Norwegian coast in 2018, Southwest of Europe in 2018 & 2019, Finnish coast in 2019, Baltic Sea in 2021 and Irish coast in 2022. These results in real maritime environment aim at demonstrating that EGNOS L1 service is suitable to support maritime navigation in ocean waters, coastal waters and harbour entrances/approaches according to the operational requirements defined in the IMO Res. A.1046 (27), being beneficial for maritime community.

Evolution of SBAS/EGNOS enabled devices in maritime

The maritime sector was one of the first communities that recognized and exploited the opportunities and advantages provided by Global Navigation Satellite Systems (GNSS). In fact, GNSS have become the primary means of obtaining Position, Navigation and Timing (PNT) information at sea. Most of the ships in the world are equipped with GNSS receivers. GPS provides the fastest and most accurate method for mariners to navigate, measure speed, and determine location. However, its performance can be enhanced by taking advantage of augmentation systems such as differential GNSS or Satellite-Based Augmentation Systems (SBAS/EGNOS), especially in terms of accuracy. Direct access to EGNOS in vessels can be achieved through EGNOS-enabled navigation receivers and EGNOS-enabled AIS transponders. This paper provides an analysis of the number of onboard devices, mainly devoted to navigation purposes, and AIS transponders which are SBAS compatible. In addition, other equipment using GNSS positioning in the maritime and inland waterways domains are also considered for the analysis of SBAS compatibility, including inland AIS, Portable Pilot Units (PPUs) and Dynamic Positioning (DP) equipment. A first survey was done in 2017 to have an overview of the percentage of SBAS enabled devices available in the maritime market [8]. Since then, the analysis has been yearly updated to understand the market evolution in terms of SBAS compatibility and its main results are summarised in this paper.
