Ajilon Technology Aerospace is looking for a Radio Navigation Engineer (E3) for an opportunity at the European Space Agency in the Netherlands


The Function

Specific Tasks:

• The work includes design, analysis and testing of radio navigation systems, with emphasis on system architecture and performance and on radio navigation receivers.

The principal tasks and responsibilities will include:

• Participation in studies on radio navigation receivers design and techniques, in particular for Galileo.

• Support to the Galileo project in the follow-on of industrial contracts for test and system receivers;

• Support to the Galileo project for system performance evaluation.

• Software / hardware simulations and laboratory testing.


Generic tasks:

• Radio Navigation system (GPS, GLONASS, GALILEO etc.) and augmentation(EGNOS, WAAS, QZSS etc.). The work includes studies: analyses and testing of navigation systems/segments/elements/technology, dissemination and navigation algorithms, including tools development; evaluation of Navigation/Positioning/Timing algorithm and techniques, user/system/segment performance assessment based on software simulators, laboratory and field measurements, and support to ESA projects in follow up of industrial procurements.

• Radio Navigation equipments covering space applications. The work includes study, design, analysis and testing of navigation/positioning/ranging/monitoring technology and receiver for space. Radio Navigation space applications performed at ESA include: scientific applications (atmospheric sounding, oceanic observation), formation flying, rendezvous and attitude determination.

• Radio Navigation equipments for terrestrial applications. The work includes study, design, analysis and testing of navigation receivers/technology for terrestrial applications and local  augmentation. Radio Navigation terrestrial applications performed at ESA are those related with high performance based on high accuracy(e.g. geodesy) and/or high integrity (e.g. civil aviation, maritime).

• Radio Navigation signals and signal processing. The work includes study, design, analysis and testing of signal and signal processing techniques including tools/equipment development and procurement. It encompasses signal structure, modulations, data dissemination, techniques for error correction, synchronisation, multipath mitigation and estimation, interference mitigation, cancellation, encryption, authentication, etc.

• Radio Navigation Laboratory equipments. The work includes definition procurement design, testing, usage of Radio Navigation equipment in support to Radio Navigation experiments and test campaigns.

• Assistance in preparation of invitation to tenders related to ESA Projects and R&D activities and contracts technical follow-up.

• Specific engineering support to space projects developed by ESA and/or by major European industries/operators.

• Validation of designs by means of analyses, simulations, laboratory testing and field trials (possibly in co-operation with third parties).

• Design, implementation and testing tasks for technological projects.

• Execution of internal R&D activities through design, prototyping, analysis and simulations.

• Simulation and testing in laboratory of Navigation systems and equipment.

• Preparation of technical documents on above subjects.

• Support to related demonstrations inside and outside ESTEC.


The work concerning laboratory activities will be performed based on the existing Radio Navigation facilities available at ESTEC.


Candidate Profile

To successfully perform the above mentioned tasks, the following background / experience is required:

• University degree (MSc minimum) or equivalent in telecommunications and signal processing as well as experience in these fields.

• Specific knowledge of radio navigation systems architecture and key performance parameters of GNSS.

• Experience in receiver design and testing.

• Detailed knowledge of Rx algorithm at User Level.

• Applicants must be eligible to security clearance by their national security administration.

• Experience in project management and industrial procurement.

• Specific knowledge in the design and testing of Radio Navigation systems and equipment.

• The specialist shall in particular have experience related with the EGNOS and/or Galileo systems and equipment and have some knowledge of Radio Navigation Simulation and testing systems.

• Specialist in the implementation, maintenance and operation of complex Radio Navigation simulation and test facilities for spacecraft, aircraft, maritime and land mobile applications.

• Some experience of commercial simulation software is desirable.

• This specialist shall have a minimum of 1-2 years of practical experience in the EGNOS and Galileo areas.
