Space-based Femtosecond Laser Filamentation

This study aimed at developing the numerical framework to investigate whether the remote generation of laser filaments from orbital altitude was theoretically feasible and in this case to gain insights on the required initial laser parameters to remotely generate a filament.

Interplanetary and Planetary Radiation Model for Human Spaceflight (IPRAM)

Gaps in existing radiation environment and effects standards adversely affect human spaceflight developments. The most important drivers in the domain of interplanetary and planetary radiation environments were investigated, identifying appropriate data sources and modelling methods to address the needs of future interplanetary manned mission design and operation.

Star Trackers for Asteroid Search

The objective of the on hand study are, to assess the potential of using Star Trackers in ESA missions currently in operation, or planned in the future, to work as a "payload of opportunity" that can be used to carry out observations with scientific or engineering interest. In particular the activities looked to:

Collaborative calibration of MEO GNSS signal biases based on LEO satellites GNSS-BICS

GNSSBICS is a feasibility study carried out in the frame of the ESA’s General Studies Programme (GSP)
by DEIMOS-Space, Deimos-Engenharia and ESA.
This activity investigated what G/S infrastructure would be necessary to develop a System, named as GNSS-BICS (GNSS Bias Calibration System), in charge of providing, under demand, the GNSS MEO S/C SISBAF (Signal-In-Space Biases Amongst Frequencies), from GNSS observations gathered by GNSS multi-frequency receivers on-board LEO satellites (potentially from different missions).

COBRA Extension of the IRIDES Experiment 13/702

The COBRA (COntactless deBRis Action) concept was studied under ESA contract and then internally by ESA, as part of ESA ́s SysNova technology assessment scheme which uses “technology challenges” and competitions to survey a comparatively large number of alternative solutions. The concept was originally proposed by an industrial consortium led by GMV form Spain with Politecnico di Milano and Thales Alenia Space from Italy. The concept came first in response to a challenge for mission concepts and technologies capable of providing a contactless Earth-bound object orbit modification system.

Weak GNSS Signal Navigation on the Moon

Global Navigation Satellite Systems (GNSS) are already used in space missions (e.g. GOCE, Swarm, Sentinel, and MetOp, among others), not only as a navigation sensor (either for autonomous orbit and attitude determination or for relative navigation) but also as a science instrument (e.g. for altimetry, global geodesy, Radio Occultation and GNSS Reflectometry applications). However, its use is usually limited to orbits or mission phases below the orbits of GNSS satellites, since GNSS satellite antennas transmit mainly in the Earth's direction.
