EGNOS-based DGNSS corrections will be generated centrally for the location of existing AIS base stations, including the required additional maritime integrity checks. Access to EGNOS data will be provided through a redundant setup. The primary source for the generation of DGNSS corrections will be EGNOS SiS. SBAS enabled GNSS receivers will be used to receive the EGNOS geostationary satellite signals and output the augmentation data in RTCA format to the central processing software. As a backup data source, the EDAS SISNeT service will be used, which delivers the same EGNOS corrections via the Internet.
EGNOS messages (RTCA format) will be converted in real time to RTCM SC-104 corrections referenced to the location of the AIS base stations. As the EGNOS system provides the same type of augmentation information over the whole of Europe with nearly homogeneous quality, it is possible to generate EGNOS-based DGNSS corrections, or in other words EGNOS Virtual Reference Station (EGNOS-VRS) corrections, for any location within the EGNOS coverage area. Customised correction data streams will be generated for each AIS base station, in order to minimise the so-called distance dependent accuracy degradation effects of DGNSS corrections.
The use of EGNOS as a source of differential corrections provides room for the rationalisation of the shore infrastructure. The GSA SC24 project Cost Benefit Analysis (CBA) results demonstrated (RD-12) that cost efficiency of the EGNOS-based approach comes from the reduction of onsite infrastructure (CAPEX), operational (OPEX) and maintenance costs (fewer spares and effort to repair) compared to classical approach of DGNSS correction generation at the transmission sites.
Another significant advantage of using EGNOS as a correction data source lies in its robustness to radiofrequency interference (jamming and spoofing) and other local effects (e.g. multipath, receiver/antenna malfunction) that can affect a classic DGNSS system. In the proposed approach, correction generation will be centralised with only the transmitting equipment at the broadcast sites. The quality of EGNOS-VRS corrections will not be affected at all by potential GNSS signal reception issues at the AIS base stations.
Furthermore, the EGNOS augmentation data itself is based on the observations of a European wide tracking network consisting of 40 Ranging Integrity Monitoring Stations (RIMS). Due to the redundant system architecture, potential local errors with an adverse effect on the measurement quality of individual RIMS sites have no or only minimal impact on the overall EGNOS performance.
In order to further reduce the infrastructure needed, the raw observation data of the same EGNOS-enabled GNSS receiver(s) that provide(s) the EGNOS RTCA data to the central server will also be used for integrity monitoring. To mitigate the impact of any interference or jamming attack near this receiver, it will be considered to use additional GNSS receivers of public network operators (e.g. EPN or IGS) located in the area of interest, providing high-quality GNSS measurement data, free of charge.
The proposed centralised EGNOS-VRS correction generation solution is based on the Pre-Broadcast Monitoring (PBM) approach to check the integrity of the corrections and will also rely on one or more Far Field Monitoring (FFM) stations that will be used to monitor the radio link availability and the quality of the transmitted signal.
