What will you be doing?

Solar activity causes ionospheric irregularities known as scintillation. Especially in equatorial regions these can have large effects on signals travelling through this atmospheric layer or relying on it, such as satellite communications, GNSS and terrestrial HF communication systems.

During the military mission in Mali, from 2014 to 2018, GNSS measurements have been done to learn more about these disturbances. The effects on GNSS during this low in solar activity were minimal and especially for dual-frequency receivers these effects can easily be mitigated. At the same time, the measurements with GNSS receivers, such as the Septentrio, showed great potential for locally measuring scintillation indicators (i.e. amplitude and phase scintillation).

Many institutes provide scintillation overviews and short-term forecasts, but on a global scale. This is done using terrestrial measurements such as the global network of the International GNSS Service (IGS), or via satellite measurements by Langmuir probes.
The objective of this thesis is to determine the additional value and quality of the local measurements in comparison with global and regional forecasts.

What do we require of you?

During this thesis you will gain valuable experience in processing measurement data, as the GNSS measurements data will be made available in their original format. Post-processing of logfiles is expected in MATLAB or Python, or any preferred programming language. Your work can take place at TNO in The Hague or at your university.

This thesis provides the opportunity to build a network at TNO and present your work for all involved organizations. We would like to work towards publication of the results. Furthermore, you will get acquainted with domain of defence, where there is a growing interest in space, while the research will also have civil and scientific applications.

What can you expect of your work situation?

TNO is an independent research organisation whose expertise and research make an important contribution to the competitiveness of companies and organisations, to the economy and to the quality of society as a whole. Innovation with purpose is what TNO stands for. With 3000 people we develop knowledge not for its own sake but for practical application. To create new products that make life more pleasant and valuable and help companies innovate. To find creative answers to the questions posed by society. We work for a variety of customers: governments, companies, service providers and non-governmental organisations. Working together on new knowledge, better products and clear recommendations for policy and processes. In everything we do, impact is the key. Our product and process innovations and recommendations are only worth something if our customers can use them to boost their competitiveness.

Your work will be carried out in our Military Operations (MO) department, which consists of approximately 60 enthusiastic academic professionals with diverse background, such as mathematics, econometrics and aerospace engineering, to public administration and history. We share a passion for applied research in het Defence and Security domain, which we mostly perform in multi-disciplinary teams.

What can TNO offer you?

You want to work on the precursor of your career; a work placement gives you an opportunity to take a good look at your prospective future employer. TNO goes a step further. It’s not just looking that interests us; you and your knowledge are essential to our innovation. That’s why we attach a great deal of value to your personal and professional development. You will, of course, be properly supervised during your work placement and be given the scope for you to get the best out of yourself. Naturally, we provide suitable work placement compensation.
