Persistent Responsive Real-Time Earth Observation small satellite constellation mission (PERTEO) is a study dedicated to provide a global democratic service to support disaster management. Earth observation and satellite-based communications play a key role to support disaster management targeting responsiveness and the persistence of the service. In the terminology of on-demand Copernicus services, responsiveness is determined by the lead-time and latency. The persistence is determined by the availability and by the revisit time of the service.

Currently GNSS Systems provide services for instantaneous absolute positioning accuracy of a few meters, assuming no local obstructions above 5-10 degrees elevation, based on the navigation signals broadcast by a MEO constellation.

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).

Developing a high-performance, but low cost satellite with very high resolution products would open the Earth Observation market to a new audience, creating a path for new applications and ultimately encouraging competitiveness.
These products are currently not often covered by the space industry and access is very limited. As such a new low cost satellite, with turnkey technology could open the market considerably. A new activity, with GSTP Element 2 and Spain, has developed a spacecraft to do just that.

During the course of the study a significant effort has been dedicated to the explorations of a very high number of configuration architectures for scenario (d), which definition became the main focus of the activity. Several hundreds of options have been analysed with a high level of detail both at mission analysis and mass budget level, to properly identify robust and feasible solutions.

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.

Over the course of this study we have convinced ourselves of the benefits of a reference architecture in particular and of an end-to-end simulator in general. Our arguments have mostly been technical ones, but the reality is that it can only be sold to the space science community by successfully making the case that it improves the science return of the mission.

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).

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.

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.
