NAV Portugal also represents the Portuguese State in the following World Civil Aviation  organizations:

The United Nations Civil Aviation Organization which operates on a global basis and has the function of setting the standards and regulations for all international civil aviation activities in the areas of air navigation and air transport;

European air navigation safety organization which includes virtually all the countries in Europe. Responsible for coordinating air traffic between European countries and for implementing the programme for the harmonisation and integration of air traffic control (EATMP), in the Civil Aviation Conference member states (ECAC).

Civil Air Navigation Services Organization; NAV Portugal is a founding member of this organisation which coordinates collaboration between air navigation service providers..

The main objective of the ESSP is to implement the contract with the European Commission that will allow the company to become the operator of the EGNOS system and the EGNOS service provider.
ESSP's mission is the provision of the EGNOS open service (OS) and safety of life service (Safety of Life-Sun) in accordance with ICAO standards and recommended practices SBAS in the region of the European Civil Aviation Conference (ECAC).
The ESSP is also responsible for providing the service EDAS (EGNOS data access service).
Founded in 2001 and initially formed as a European economic interest Grouping (EEIG), as this legal form was appropriate to the stage of development of the company, the ESSP (European satellite service provider) was transformed in 2008 into a new limited-liability company ESSP SAS-and moved from Brussels to Toulouse.
Its shareholders are seven air navigation service providers (ANSP), Europeans who were also members of the EOIG FROM initial (EGNOS Operator and Infrastructure Group), are the following:
AENA (Spain)
Dfs (Germany)
ENAV (Italy)
NATS (England)
NAV Portugal
Skyguide (Switzerland)


COOPANS (Cooperation between Air Navigation Service Providers) is an international partnership between the air navigation service providers of Austria (Austro Control), Croatia (Croatia Control), Denmark (Naviair), Ireland (Irish Aviation Authority), Portugal (NAV Portugal) and Sweden (LFV). Thales is a chosen supplier (industry partner) for COOPANS. The harmonisation of functionalities and joint investments enable the cost-effective implementation of an advanced and unified air traffic management system.


On the 17 May 2013, the Portuguese Ministry of the Economy and Employment and the Spanish Ministry of Development and Transport signed in Lisbon the State Agreement for the establishment of a Functional Airspace Block of Southwest (SWFAB) in accordance with the provisions of the EU regulation on the implementation of the SES.

The State Agreement applies to Portuguese and Spanish States, but the implementation of the FAB also involves cooperation and coordination between air navigation service providers of both countries, and NAV Portugal and ENAIRE. In this respect, both air navigation service providers have worked since 2001 in the framework of a memorandum of understanding between the two entities, in similar lines and in front of the goals of the European initiative and in particular of the FAB concept.

The establishment of FABs, along with the performance framework and the network functions, form the basis for the success of the Single European Sky, helping to manage the expected air traffic growth in European in a sustainable manner.

The establishment of FABs will reduce the negative impact of fragmentation in the European airspace, enabling significant performance improvements to the air traffic management and air navigation services.

The initiative of Southwestern Portugal Spain FAB aims to achieve

• Increased cooperation between all relevant stakeholders of the aviation for the provision of air navigation services;

• Optimizing and better provision of air navigation services performance (in terms of operational efficiency, capacity, cost-efficiency and environmental impact reduction) in line with the performance objectives of the EU;

• Increased interoperability;

• Increased mode and integration in technology, systems and their associated support processes.
