EU RESEARCH FRAMEWORK PROGRAMME:	MSCA Doctoral Network GLITTER | Gnss-r sateLlITe earTh observation UKRI grant N° G127873

GENERAL:

GNSS-R is a technique to carry out Earth observation based on reflections on the ground (or sea, or ice) of signals originating from GNSS (Global Navigation Satellite System) signals. The proposed project consists of educating a new generation of experts, at doctoral level, able to bring a qualitative leap to this technology. The scientific and technological goal consists of developing such systems based on a synchronized constellation of Cubesats. An important advantage of this arrangement is the very low cost of cubesats and the possibility to increase resolution based on beamforming from the satellites. Ground truth, as well as some of the methods, will originate from near-field radar technology. This will require further research on all segments of GNSS-R technology and beyond: launching and adjustment of cubesat formations, RF synchronization, interferometry between moving platforms, calibration of RF front-ends, ground testing making use of drones, cubesat systems, on-board processing, data transfer and analysis, translation into ground truth and into predictions important for climate change studies and for optimal territory management. The project may also benefit to other technologies making use of interferometry, such as radioastronomy and phased array- based communications. It is also expected to assist industry segments making use of GNSS signals, such as precision agriculture, forestry and sea and land management.

Training programme for recruited researchers:

GLITTER offers a rich inter-sector training program, with private and academic partners, recognized in all segments of satellite-based Earth observation at microwaves. The program has been designed taking into consideration the “triple i” aspects: international, inter-sectoral, and inter-disciplinary,

thanks to the different competences brought by each partner of the network as well as lecturer outside of the consortium with complementary competences.

Each Doctoral Candidate (DC) will benefit from an individual and customized training program, established in the Personal Career Development Plan (PCDP) that offers a combination of research specific and transferable skills. First, the core training, often but not always local, with order of 5 ECTs on specialized topics, close to a given DC personal project, to allow them to acquire a deep understanding of their subject. Second, the network-wide training will be offered by the consortium during the whole project life cycle through 4 training schools and 3 workshops. The workshops will include practical system-based development.

Job conditions

Each host organisation will appoint the successful applicant under an employment contract with a very competitive salary. The fellow is expected to join their host organisation starting from 1st October 2024 (estimated time). Additional funding for participation to courses, workshops, conferences, etc. is ensured.

The funds for this post are available for 36 months.

The Fellowship is offered in conjunction with a PhD position, subject to the Fellow satisfying the University’s admission requirements for PhD Study. Therefore, candidates will need to submit a formal application to the University of Cambridge for a PhD in Physics.

EU eligibility criteria for candidates:

The Doctoral Candidate (DC) may be a national of a Member State, of an Associated Country or of any Third Country.

Researchers must be doctoral candidates (no doctoral degree at the date of recruitment)

The DC must not have resided or carried out activity (work, studies, etc.) in the country of the host organisation for more than 12 months in the 3 years immediately prior to the recruitment. (Compulsory national service, short stays such as holidays, and time spent as part of a procedure for obtaining refugee status under the Geneva Convention are not considered)

Candidates profile:

• MSc degree in Physics, Electronic/Telecommunications Engineering, or related fields.

Description of the project concerned by this offer (DC3)

The GLITTER project is focused on advancing GNSS-reflectometry, among others through the use of a swarm of CubSats to receive the signals scattered by the Earth in an interferometric way. That is, the signals are received by each CubeSat are coherently combined, as is currently done with radiotelescopes, in order to form a synthetic beam and so to improve the resolution on the ground, typically from 10 km to 1 km. This PhD aims at ensuring a good RF coherency between the different satellites.

One of the main challenges for modern GNSS-R applications is the detection of extremely faint signals in the presence of noise and/or interference. Equally, radio cosmology from space-based platforms, aims at the detection and study of minute radio signals of cosmological origin, in the presence of much brighter noise signals. From a front-end / antenna point of view this calls for innovative designs of both the antenna and radio receiver as well as the calibration techniques to enable maximum science extraction. Frequency bandwidth, spectral smoothness and compactness are some of the key design drivers for such instruments to be airborne on small, power-limited platforms. Exploiting state of the art antenna technology (e.g. metasurfaces and lenses) the PhD student will work

on to design of novel antenna systems and calibration techniques for application-specific solutions, meeting the need for high information and data volume and high dynamic range. The student will be exposed to the extra-disciplinary field through a secondment at a partner close to the end application to realize the impact of instrumental design and calibration. At the end of the project, we would expect the student to have developed suitable metrics to quantify the performance of an optimal antenna system design for modern GNSS-R and space-based Radio Astronomy applications; Design and computational modelling of a wideband, light and steerable antenna for GNSS-R applications (also contributing to the prototyping and test of “best” design according to the metrics developed); and to develop suitable calibration strategies for the specific application.

The PhD candidate will do a research stay (6 months) at the Université catholique de Louvain, Louvain-la-Neuve, Belgium, to work with Prof. Christophe Craeye, lead of the GLITTER project.
