Autonomous Surface Vessels (ASVs) are rapidly approaching market-readiness, with numerous partly-autonomous and teleoperated systems either under development or already performing operational demonstrations for applications such as bathymetric surveying (SEA-KIT Maxlimer, Deep BV), maintenance of offshore installations (Thales Halcyon), and commercial shipping (Yara Birkeland, Maersk VISTULA-Class).

The objective of ESA PREGO activity (ESA/ESOC contract 4000115173/15/F/MOS) is to improve the capacities on re-entry prediction thanks to a complete analysis of the outstanding data set related to the GOCE re-entry occurred in October/November 2013.

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).

Chlorophyll fluorescence (CF) is a natural spectral emission resulting from the interaction of plant chlorophyll pigment with visible light (typically 400‐700 nm). In photosynthesizing tissues, red and far‐red light can be emitted from any chlorophyll‐containing plant tissues which are exposed to light: primarily foliage, but also green stems, green exposed roots, floral structures, many fruits, and green seeds.
