ANSPs from UK and Poland signed the EWA with ESSP
These last months have been very fruitful in terms of collaboration with different European ANSPs, finally materialized by the signature of new EGNOS Working Agreements (EWA); In February ESSP signed the EWA with PANSA, the ANSP from Poland. At the end of March, another EWA was signed with Exeter and Devon Airport Limited (EDAL), an ANSP managing and operating Exeter International Airport in the UK.
“LPV approaches using EGNOS will complement the current precision and non-precision approaches at Exeter International Airport,” said Stephen Wiltshire, EDAL Operations Director “Adding an option to carry out LPV approaches will benefit aircrews wishing to use Exeter.”
The signature of the EWA between an ANSP and the ESSP as EGNOS service provider is the first step for LPV procedures implementation at European countries within the EGNOS service area. After the signature, ANSPs are responsible for the EGNOS-based procedures publication within their territories.
The SAFIR (Satellite navigation services for AFrIcan Region) project under the EU-Africa Common Strategy as well as the Joint EU-Africa Partnership is holding its first Working Session in Dakar (Senegal) on 22/23/24 May 2013.
The 3-day workshop dedicated to EGNOS awareness and technical aspects will focus on:
SAFIR will cover the costs (air transport, meals and accommodation) of 20 attendees including:
- Representatives of African stakeholders concerned with GNSS applications invited directly by the SAFIR Project Implementation Team (PIT),
- Other African experts who may apply directly in e-mailing before 28 April (6 pm UT) amotivation letter plus a CV to the 3 Key Experts of the PIT:
Logistic Information and detailed agenda will be given in due time to the participants selected by the PIT and approved by the ACP Secretariat and the European Commission.
The EC has released a new version of the EDAS Service Definition Document (EDAS SDD) with the aim to reflect the new services and associated added value that EDAS will provide to its users. The addition of these new services is the consequence of EC strategy to continuously improve all the EGNOS services . The new EDAS SDD is the first update of the version published for the EDAS Service Declaration in July 2012, embarking also several improvements based on users feedback.
The Document provides a description of the target EGNOS service, the commitment for the community in terms of performance and the service conditions of use.
EDAS, the EGNOS Data Access Service, is the third EGNOS service available to users, after the Open Service and the Safety-of-Life Service. Unlike the other two EGNOS services (SoL and OS), EDAS does not provide its products to the users through the EGNOS Signal-In-Space, but throught Internet. EDAS services are oriented to users in different domains of application such as Location Based Services (LBS), Assisted-GNSS (A-GNSS) concepts, a broad range of services in professional GNSS markets, and related R&D activities.
The real-time and historical data provided by EDAS are the GNSS observations and navigation data collected by the entire network of EGNOS stations, the EGNOS augmentation messages, as normally received by SoL and OS users via the EGNOS geostationary satellites and the Ionosphere maps providing TEC information, which are based on the EGNOS processing.
The new services that are now available to users are:
The addition of the aforementioned set of new EDAS services to the EDAS portfolio will bring an important added value to EDAS users:
The EC has released a new version of the EGNOS Open Service Definition Document (OS SDD v2.0) with the aim to reflect the improvements acomplished in the EGNOS system during the last years, particulary the changes related to the extension of the service area and the accuracy provided by EGNOS. The new OS SDD is an update of v1.1, which was released in October 2009, as of the Declaration of the EGNOS Open Service.
This update is of particular interest to receiver manufacturers, GNSS applications developers and users.
The V2.0 shows significant improvements on the geographic coverage of the EGNOS Open Service, as can be seen from this delta map from SDD V1.1 to SDD V2.0.
Spain is the latest European country to sign up to implement EGNOS-based approach procedures for its airports with the signing of an agreement at the World ATM Congress in Madrid. The first Spanish airport to implement EGNOS-based procedures should be up and running by this summer.
The World ATM Congress in Madrid was the background for the public signing of the latest EGNOS Working Agreement (EWA). Agreement between the European Satellite Services Provider (ESSP) and the Spanish airports and Air Navigation Services Provider (Aena) was reached in late December 2012, but the formal signing of the EWA took place at a ceremony in Madrid on February 13th.
The arrangement between ESSP and Aena is a key step in the implementation of EGNOS-based approach procedures, specifically localiser performance with vertical guidance (LPV) procedures, throughout Spain.
The agreement was sealed by ESSP President, Dirk Werquin, and Aena's Air Navigation Director, Ignacio Gonzalez, at the CANSO ATM Congress.
With the signed EWA, Spanish airports can now start publishing EGNOS-based procedures that can improve safety and accessibility and boost the efficiency of the aviation transport sector.
"The use of EGNOS for LPV approach procedures is already a reality in Europe," said Dirk Werquin. "ESSP, as the EGNOS service provider, is proud that Spain has also started to benefit from the EGNOS service joining other European countries such as France, Switzerland, Germany and Italy."
EGNOS provides a cost-effective alternative to current ILS procedures offering similar performance without the need for extensive ground-based infrastructure.
"Spanish airports will shortly profit from certified EGNOS Safety- of- Life Signal," commented Ignacio Gonzalez. "With the signing of this agreement, Aena, which has from the very beginning been engaged in the development of EGNOS for aviation and pioneered the first ever LPV approach and landing procedure within the European Commission funded GIANT project during FP6, is now ready to provide EGNOS-based daily airport operations in Spain."
The northern airport of Santander will be the first Spanish airport to implement EGNOS procedures by this summer.
ASECNA (Agence pour la Sécurité de la Navigation Aérienne en Afrique et à Madagascar) in consortium with Egis, Pildo Labs and ESSP have been designated by the ACP Group (African, Caribbean and Pacific Group of States) to implement the SAFIR Project, funded by the European Commission through the 10thEDF Intra-ACP envelope, with the objective of building capacity within African ACP countries for the future deployment of GNSS/EGNOS in the region. The fund is secured within the framework of the EU-Africa common Strategy adopted in 2005 and the Joint EU-Africa Partnership established in December 2007.
The SAFIR (Satellite navigation services for AFrican Region) project will last two years and will cover the set-up, staffing and operations of an EGNOS-Africa Joint Programme Office (JPO) with a proper regional participation of the various beneficiary countries. The missions of the future JPO will be to define the baseline and oversee the subsequent implementation phase for the specification and procurement of the development and deployment of GNSS/EGNOS in Africa.
SAFIR will also set up and support a number of technical Working Sessions composed of regional stakeholders concerned with GNSS/EGNOS in sub-Saharian Africa, which will address all aspects of EGNOS-Africa system development and service provision in preparation of the infrastructure deployment phase, including system performance, applications, certification policy, industrial issues, maintenance, liability policy, governance structure …
Several studies of the implementation of SBAS (Satellite Based Augmentation System) services in Africa have been carried out and have indicated robust and undeniable social and economic benefits in many sectors (transport, land management, oil and mining industry …) and especially in aviation: safety improvement, better control coverage, opening of new routes, reduction of transport costs…
