Advances in Technological Quantum Optics

Commonly used classical cryptographic protocols, such as the RSA-protocol, rely on the hardness of computational problems. With the advent of quantum computing (QC), the hardness assumptions of these problems is nullified, since they can be solved efficiently on a QC. On the other hand, the security of Quantum key distribution (QKD) rests upon the very laws of physics and guarantees information-theoretic security, which not only enables tap-proof communication at present, but also prevents any future technology to crack encrypted messages.

On the Use of Mega-Constellation Services in Space

This activity investigates how mega-constellations can be used to provide low-Earth orbit (LEO) spacecraft with broadband low-latency services, a novel Concept with potential to disrupt spacecraft design, operation, and performance by allowing spacecraft to access mega-constellations’ enormous resources (Tbit/s throughputs) and global coverage at a lower cost than traditional data relay systems and ground station networks (two to fifty times cheaper, that is, a few hundred to a few thousand dollars per month for a daily net capacity from hundredths of Gbit up to almost ten Tbit).

Angle Carrier Phase Altimetry with GNSS Reflected Signals: exploring beyond the PRETTY mission

This activity is intended to investigate the Grazing Angle (GA) Carrier Phase Altimetry (CaPA) using signals transmitted by the Global Navigation Satellite Systems (GNSS). The CaPA technique requires that the electromagnetic signal reflects coherently rather than in a diffuse regime. The hypothesis is that GA geometries enhance the likelihood of coherence scattering. It was also hypothesized that the combination of signals at slightly different frequency bands could expand the coherence conditions (widelane techniques, WL).

Magnetic Powder as Propellant in Electrostatic Thrusters (MPEP)

The main objectives of this project were to develop a thruster prototype based on magnetic powder electrostatic propulsion and to test it in vacuum with direct thrust measurements. The aim was to check the robustness of the concept and to measure and calculate important performance parameters such as thrust and specific impulse, to allow a comparison with other thruster technologies. This project demonstrated for the first time the feasibility of electrostatic propulsion based on powder emission.

Magnetic Field Perturbations by Thermo-Electric Effects

Moving charges produce magnetic fields. Since thermal transients produce an electric current, thermal transients produce magnetic fields. It has been shown that the generation of these magnetic fields in the vicinity of sensitive instruments leads to a degradation of recorded data.

Getting closer to a theoretical solution and to an effective mitigation technique will help magnetic missions in ESA’s Science programme, Earth Observation programme and, in fact, all missions that employ magnetic-sensitive sensors.

Feasibility of using platform magnetometers to observe and detect space weather events

Magnetometers are fundamental instruments used in planetary and space science. They are able to measure magnetic fields originating in a planet’s interior, past fields encapsulated in rocks in the crust, as well as magnetic fields generated by the motion of charged particles in the plasma environments of ionospheres, magnetospheres and interplanetary space.
