On April 9, 2019 Oro navigacija and European GNSS Agency (GSA) signed the Grant Agreement regarding partial funding for EGNOS Lithuania implementation project.
Under the Delegation Agreement concluded between the European Commission and the GSA on the Exploitation Phase of the European Geostationary Navigation Overlay Service (EGNOS), the GSA is entrusted with the management of operational activities relating to the exploitation of the EGNOS Programme, including infrastructure management, maintenance and continuous improvement in accordance with the Programme Management Plan. Within this framework, and in accordance with the EGNOS Exploitation Grants Plan 2017, the GSA launched a call for proposals to increase EGNOS adoption in civil aviation and Oro navigacija‘s proposal was selected as eligible one.
The EGNOS Lithuania project envisages preparation and implementation of EGNOS-based RNP APCH (Required Navigation Performance Approach) procedures to LPV/LPV200 minima in Vilnius, Kaunas and Palanga airports. The EGNOS service enables RNP APCH down to a minimum as low as 200 ft (~60 meters). These LPV-200 approaches are considered as ILS (Instrumental Landing System) look-alike, but without the need for the expensive ground infrastructure required for ILS or upgrade to existing certified EGNOS receivers.
To implement the EGNOS Lithuania project, Oro navigacija must acquire certain products and services:- procedure design software, EGNOS data recording and analysis tool and flight validation services. The enterprise will also have to perform site survey, prepare obstacle map, perform safety assessment, ground and flight validations, conduct ATCO training and publish relevant information in AIP.
The EGNOS Lithuania project implementation began on April 9, 2019 and has to be completed by January 31, 2021. EGNOS adoption and procedures for LPV/LPV200 minima are planned firstly in Vilnius (by February 29, 2020), secondly in Kaunas (by July 31, 2020) and finally, in Palanga (by January 31, 2021). GSA is to provide funding of 60 per cent of the total project budget (250 527, 66 Eur), the remaining part of the budget will be at Oro navigacija’s expense.
EGNOS Service Provider, ESSP, and the Lithuanian Air Navigation Service Provider (ANSP) SE Oro navigacija have recently signed an EGNOS Working Agreement (EWA), as a key first step for the implementation of EGNOS-based approach procedures (LPV SBAS procedures) in Lithuania.
EGNOS is European Geostationary Navigation Overlay Service, it provides an augmentation signal to the Global Positioning System (GPS) Standard Positioning Service (SPS). The EGNOS service enables RNP APCH (Required Navigation Performance Approach) down to a minimum as low as 200 ft (~60 meters). These EGNOS-based approaches (also called EGNOS LPV-200) are considered as ILS (Instrumental Landing System) look-alike, but without the need for the expensive ground infrastructure required for ILS or upgrade to existing certified EGNOS receivers.
The EGNOS service is to be adapted in 3 international airports of Lithuania: Vilnius, Kaunas and Palanga.
The agreement was signed on the 10th October 2018, and it establishes the operational and legal framework to use the EGNOS Safety-of-Life Service as a navigation aid between the EGNOS Service Provider – ESSP - and the Airport / Navigation entity willing to use this service. This agreement is framed into the EU Space Programme actions to get the highest security rates and accuracy systems in aviation through Satellite Based Navigation Protocol.
Mr. Mindaugas Gustys, CEO of SE Oro navigacija said “Our company aims at providing Lithuania’s airspace users opportunities to improve their performance and seeks to become the region’s innovation leader. EGNOS adoption is an important step towards the goals and we are glad to support EU strategy to maximize the use of EGNOS in aviation and to adopt EGNOS in three main airports of Lithuania”.
Oro navigacija is now to perform the relevant EGNOS adoption-related activities, including site survey, preparation of RNP APCH procedures to LPV/LPV200 minima, safety assessment, ground and flight validation and publication on AIP.
This agreement reinforces the use of EGNOS within the Baltic and neighboring countries, where 17 other agreements have already been signed: 1 in Norway, 7 in Sweden and 4 in Denmark, 2 in Estonia, 2 in Poland and 1 in Finland, but this is just the beginning, as more airports and Air Navigation Service Providers (ANSPs) are also working to obtain the EGNOS Working Agreement (EWA) to implement GNSS-based approach procedures soon.
