Over the last few years schemes based on minimal kinetic models for the Boltzmann equation are becoming increasingly popular as a reliable alternative over conventional Computational Fluid Dynamics (CFD) techniques. Due to the flexibility afforded by its close connection to the kinetic theory recent research has led to major improvements, including consistent models for aerothermodynamics and highly compressible flow in low gravity operating conditions.

ESE Ergonomic User Interfaces (ESE-ERGO)
In parallel with the design and implementation of the current operational Proba-V Mission Exploitation Platform (PV-MEP), based upon a series of building blocks (i.e. software components) prototyped in previous technology development projects, various standardization activities (led by ESA in collaboration with the Open Geospatial Consortium and the Committee on Earth Observation Satellites) have been carried out, in order to make such developed software components aligned and interoperable with the current landscape in EO data access and exploitation (like e.g.

There is a specific requirement on the new land services focusing on continuous change monitoring. The current operational methods of land cover change detection are based on bi-temporal analysis for two points in time. These approaches are applied to 3 to 6 years mapping campaigns, while land cover changes occur continually. ;With this 3 to 6 year gap between inventories, all land change processes occurring in between are not captured. Full-fledged Land Cover Continuous Monitoring system of the land evolution is provided for EEA.

MicroMHiDe: Technologies for Microsatellites Multispectral High Definition Imager.
The development of miniaturized high performance avionics allows the building of microsatellites platforms with the high pointing stability and accuracy. This new generation of microsatellites could embark high-resolution optical systems, but given limited volume and power, the instrument will be limited in SNR. A new generation of hybrid detectors, known as CCD-in-CMOS detectors, can allow circumventing SNR limitations by operating in Time Delay Integration (TDI). This type of operation was, until recently, limited to CCD detectors that are very costly and power hungry.

This activity concerns execution of regular irradiation test campaigns on EEE components for flight on ESA and European space missions. Up to 360 hours per year of beam time is available free of charge on a priority basis for ESA. Additionally, a minimum of 500 hours per year is available for ESA sub-contractors, research institutes and other interested users at preferential hourly rates. The agency provides the facility with a detailed work programme of the test campaigns. Subsequently, the facility performs test campaign scheduling (in agreement with the Agency).

Experimental characterisation of transient flow phenomena in cryogenic Fluids
The activity focuses in particular when considering multiple re-ignition of upperstages. This entails waterhammer effects or pre-combustion phenomena where propellants undergo drastic changes due to sudden exposure to near-vacuum conditions. To allow proper modelling, detailed experiments need to be created for typical multi-phase, multi-component flow.
 
Following activities are foreseen:
 
  • Evaluation of the liquid front behaviour during waterhammer prior, during and after impact for different operational conditions.

Satellites in all application domains include a communication subsystem with similar core functions, specific features, and different operating frequencies. ;;Central to this subsystem is the Transponder equipment. ;Its current implementations already include flexibility in terms, e.g. of modulation and coding schemes. ;However missions placing specific requirements must still bear the cost of adaptations. ;Moreover the accommodation (power, mass) of such equipment is a burden for smaller missions.
