To answer the necessity of an embedded systems software company in Portugal, in 1987 a Portuguese engineering team was selected to be part of the development of the SEWACO system (Sensors and Weapons Allocation and Command) for the Vasco da Gama-class frigates.
On May 23rd 1988, EDISOFT was formally established as a Combat System Software Maintenance company. From the beginning, EDISOFT contributed to the Portuguese Navy's modernisation, providing operational and logistic support.
Likewise, it took a stance in international value chains, allowing the integral development of combat systems in Portugal that were later sold on the world market. The modernisation of the Portuguese Air Traffic Control System was a landmark on a civilian field. In 1994, EDISOFT moved in to the Space Technology Domain, participating in the establishment of the Western European Union's Satellite Centre.
In 2013, THALES reinforced its shareholding position in EDISOFT to 65%, partnering with the Portuguese MoD holding company - EMPORDEF, Empresa Portuguesa de Defesa (SGPS) with a 17,5% and the Portuguese Air Navigation Operator, Navegação Aérea de Portugal, NAV Portugal, E.P.E., with a 17,5%.
Today, EDISOFT has a regular presence in the two largest programmes under the European Space Agency’s auspices: EGNOS and GALILEO. Additionally EDISOFT has begun to develop collective security strategic systems, dedicated to the civil protection field, with projects like the Decision-Making Support System for the National Crisis Management System and PROCIV-Net, the European network.
