2 – Context and subject of the internship

As part of several of these products, Syntony has developed various spatialized GNSS receivers, as well as a GNSS signal simulator, based on a Software Defined Radio (SDR) architecture.

The subject of the internship proposed by SYNTONY consists in the realization of studies and prototyping of algorithms allowing the characterization of the ionospheric (Iono-Sensing, TEC map, scintillation,…) by a GNSS receiver in LEO orbit.

The 3D reconstruction of ionospheric layers based on ionospheric delay measurements is part of Syntony’s medium- and short-term evolution objectives on several GNSS receiver product lines.

To this end, various studies have been carried out within the Syntony R&D team, the objective of the internship subject will be to carry out a state of the art on the methods of 3D reconstruction of the upper layers of the Earth’s atmosphere and more particularly of the ionosphere via tomographic methods and/or geo-statistical approaches (kriging) from iono delay measurement (iono-free L1/L5 combination). For this purpose, CONSTELLATOR, Syntony’s proprietary GNSS signal simulator, will be used.

Studies on the characterization and simulation of the lower layers of the atmosphere are also planned in addition to Syntony’s Earth Observation activity (radio-occultation and signal processing estimator dedicated: Doppler measurement and bending angle estimation). Exchanges with university teams are also to be expected as part of the internship.
