Wideband Cavity-Backed CubeSat Antenna in S band

Anja Skrivervik, Miroslav Veljovic

The Telemetry, Tracking and Command (TT&C) antennas are a crucial component of small satellites, as their in-orbit attitude is not always well-defined. The TT&C antenna design for a CubeSat is an even more challenging task, considering the volume restricti ...

Raman lidar in operational meteorology

Valentin Simeonov, Bertrand Calpini, Todor Dinoev, Ilya Serikov

Water vapor and temperature spatial distribution and their temporal evolution are among the most important parameters in numerical weather forecasting and climate models. The operational relative humidity/temperature profiling in meteorology is carried out ...

Compact Orthomode Transducer with Broadband Beamforming Capability

Juan Ramon Mosig, Anja Skrivervik, Emile Jacques de Rijk

A compact and broadband orthomode transducer (OMT) with two dual linearly polarized ports is reported here for the first time. The component is based on a combination of two ridged Boifot junctions through a series of power dividers that act as an embedded ...

Guidance, Navigation and Control for Autonomous Rendezvous and Docking of Nano-Satellites

Camille Sébastien Pirat

Is it possible to dock CubeSats in Low Earth Orbit? Challenges are associated with the level of miniaturisation: the docking accuracy is driven by the docking mechanism dimensions. The achievable docking performance with the Guidance, Navigation and Contro ...

Robust Software Development for University-Built Satellites

Simon Bliudze, Anton Ivanov

Satellites and other complex systems now become more and more software dependent. Even nano satellites have complexity that can be compared to scientific instruments launched to Mars. COTS components and subsystems may now be purchased to support payload d ...

Cost-effective dual-polarised leaky-wave antennas enabled by three-dimensional printing

Juan Ramon Mosig, Emile Jacques de Rijk, Tomislav Debogovic, Maria Garcia Vigueras, Esteban Menargues Gomez

This study proposes a compact dual-polarised directive radiator whose complex prototyping is enabled by additive manufacturing. In addition to monolithic implementation, stereolitography followed by metal coating, it also provides high radio-frequency perf ...

Joint Anomaly Detection and Spectral Unmixing for Planetary Hyperspectral Images

Harold Gabriel Eugène Justin Clenet, Nicolas Courty

Hyperspectral (HS) images are commonly used in the context of planetary exploration, particularly for the analysis of the composition of planets. As several instruments have been sent throughout the Solar System, a huge quantity of data is getting availabl ...

Efficient global optimization of reservoir geomechanical parameters based on synthetic aperture radar-derived ground displacements

Francesco Comola

When large volumes of fluids are removed from or injected into underground formations for, e.g., hydrocarbon and water production, CO_2 storage, gas storage, and geothermal energy exploitation, monitoring of surface deformations coupled to numerical modeli ...
