GNSS observations, as taken by global GNSS sensor networks, are affected by a multitude of effects impacting the quality of the GNSS observations itself as well as the derived products. This is especially true for high accuracy products like precise orbits and clocks and also for corrections applied for real time applications. The effects impacting the GNSS observations range from unexpected GNSS behaviour, atmospheric disturbances (e.g. scintillation), environmental (e.g. multipath, antenna, ?) and seasonal effects up to those which are depending on the GNSS receiver behaviour.

SIDLOC (Spacecraft Identification and Localization) is a new transmission scheme proposed by Libre Space Foundation to enable LEO satellite identification and tracking. The SIDLOC system relies on a reduced size autonomous transmitter that requires minimal integration and area on the carrier spacecraft. The ground segment of the SIDLOC system utilizes the existing SatNOGS network and the UHF band to perform the signal demodulation and identification. The SIDLOC system uses DSSS (Direct Sequence Spread Spectrum) PSK modulated signals with an effective bitrate of ~50 bits/s.

The main objective of this activity was to design and develop an innovative virtual lab for Mars experiments, where AI methods are used to improve orbital imagery resolution, as well to obtain terrain features based on local images from rovers. Two different methods were used to recreate the virtual environment. The first one was dedicated to process low resolution images from orbital information. The main contribution in this sense was the use of AI to increase the resolution of these images.

The AERODEM is an ESA demonstration mission that will implement an aerocapture phase in order to provide an atmospheric ∆V instead of a standard chemical one for orbiting a SpaceCraft around Mars. The aerocapture technique currently studied relies on a discrete event drag modulation technique that modifies only once the aerocapture module ballistic coefficient by separating / retracting the heatshield.

An interplanetary probe must decelerate from a hyperbolic interplanetory trajectory to an orbital trajectory when it arrives at its destination. Currently, this maneuvre is achieved using chemical propulsion, which means that propellant makes up a significant fraction of the vehicle mass. Aerocapture is an alternative concept that instead uses aerodynamic drag from the athmosphere of the planet to decelerate the arriving spacecraft.

Project HyperClass aimed at accelerating the technology to process spectra received from single pixel images of space objects and:

i) extract the material composition of the object,

ii) classify the object according to a set of predefined features,

iii) estimate the attitude motion from the spectral lightcurve.
