Intern in The Egnos Development and Ivq Section, Mbse Application to Egnos

Intern in the EGNOS Development and IVQ Section, MBSE Application to EGNOS (sub)systems- **Job Requisition ID**:19838- **Date Posted**:1 November 2025- **Closing Date**:30 November 2025 23:59 CET/CEST- **Publication**:External Only- **Type of Contract**:Intern- **Directorate**:Navigation- **Workplace**:Toulouse, FR**Location**
- EGNOS Project Office, Toulouse, France.
** Our team and mission**-
-The EGNOS and SBAS Division is responsible for the development of the EGNOS system and its qualification, in its role as Design and Procurement Agent, under the programme management of the European Commission (EC). Phase CD of Version 3 of EGNOS system is currently under development.-The Division is also managing several Research and Development activities under the Horizon Europe Infrastructure and NAVISP Programmes and is supporting ASECNA for the procurement of the African SBAS.-You will be embedded in a multidisciplinary team led by experienced engineers and project managers. You will benefit from mentorship, structured onboarding, and access to ESA’s technical resources. The Toulouse office provides a professional and welcoming atmosphere, with opportunities to observe project reviews, technical panels, and collaborative workshops.-This internship offers a unique opportunity to gain hands-on experience in satellite navigation technologies, contribute to real-world projects, and develop skills in system engineering, data analysis, and collaborative research. The environment is ideal for students passionate about space, navigation, and innovation.-
** Field(s) of activity for the internship**-

The EGNOS V3.1 System is composed of 39 Remote reference stations, 2 Main Control Centres (hosting in particular the central processing Facilities) and 6 Uplink Stations to connect to 3 Geostationary satellites - All sites being interconnected by a dedicated Real-time Wide Area Network.
EGNOS V3.1 design is the result of a complex multi-disciplinary exercise implementing stringent performance, safety, security and operability requirements into several interconnected sub-systems.-You will be integrated in the EGNOS Sub-Systems team, responsible for the subsystems development and system Integration, Validation and Qualification (IVQ) activities and you will interact with other teams, in particular System engineering.-Your objective during this internship is to get acquainted and implement Model Based System Engineering (MBSE) methodology to develop EGNOS (sub)system models. In particular, you will:
-- familiarise with EGNOS V3 MBSE methodology and the MBSE tool used by ESA (i.e. capella);
- propose methodology to verify the model (semantics);
- identify a subset of EGNOS subsystem use cases, modes, functions, and interfaces for implementation in the MBSE tool; you will take the existing requirements and design documentation of EGNOS next-generation subsystems as your starting point;
- link the defined subsystem models with requirements to build complete Design Definition and Design Justification files; the model will simulate both static and dynamic subsystem behaviour with internal and/or external interfaces, testing state and mode transitions;
- propose and implement documentation export means to produce design and justification documentation and interface control documents.
