Thermal dissipation is a recurrent issue in systems and a real concern in satellite thermal joints for space companies such as Thales Aliena Space (TAS). This problem is addressed with time-consuming and costly tests under simulated space conditions (using TVAC). This study aimed to implement Touch Sensity (TS) solution to detect eventual thermal decoupling in thermal joints via pressure monitoring in order to enhance joint workmanship validation process. Functionalizing joints with TS sensing device enabled a pressure distribution visualization at the interface.

Space application represents a challenge for the lubrication of tribological components from two perspectives – performance and cleanliness. Due to the vacuum of space, and in particular in the presence of sensitive (e.g. optical) components, an extremely low volatility is required to limit evaporation or outgassing, which can lead to lubricant loss and contamination issues.

A major concern when dealing with test, validation and in-flight fault diagnosis of On-Board Software, whose complexity is continuously increasing, thanks notably to the increased computational power provided by modern microprocessors, is the level of observability that is provided to software and hardware engineers. In general terms, the more observability is provided to the engineering teams, the easier it is to diagnose an anomaly. Classical observability mechanisms are not enough to provide the needed observability of nowadays avionics systems.

The activity shall investigate the change in SEY (Secondary Emission Yield) properties due to storage conditions prior integration in the satellite. This parameter has a direct impact in the power handling (Multipactor threshold) of the RF component. The activity shall cover the changes in the threshold over time at typical storage conditions. To achieve successful results, the activity shall commence with a review of the Hatch-Williams curves with new test samples. These samples shall be used for the whole duration of the activity to study the aging process.

The simultaneous development proposed in the frame of this activity will allow to optimize the commonalities between the two PPUs and to reduce the development costs by looking for similar electrical architecture, packaging concepts and technologies. Ultimately, the two PPUs resulting from this activity will be coupled with HEMPT and HET thrusters developed in the frame of two H2020 EPIC programmes.
 
The activity will be executed in 3 steps:

Nowadays power control units design is unique and it depends on the specific application. Should the needs change, a new development is needed, thus increasing the development time and the non-recurrent-costs. Given the critically of the power conditioning module, redundancy and triple majority voting are needed, adding complexity to the design.

Within the domain of smart manufacturing, the acquisition of data is of fundamental importance. There is clearly a need to extract as much information from the manufacturing process as possible (big data) through the use of sensor technology and in line process monitoring. There are a wide range of sensors which are commercially available which are used in a number of manufacturing sectors (automotive, aerospace, etc). Types of sensors include temperature, pressure, strain, and acoustics.

Hardware/software (HW/SW) co-design refers to the simultaneous consideration of hardware and software within the design process, employing tools such as virtual platforms. A Virtual Platform is a software based system that can fully mirror the functionality of a target System-on-Chip (soc) or board, combining high-speed processor simulators and high-level, fully functional models of the hardware building blocks, to provide an abstract, executable representation of the hardware to software developers and to system architects.

Space thermal engineering relies heavily on numerical models and test data for the
design and verification of products and vehicles. However, the numerical models can
require too much computing resources to be effective for certain activities, such as
design optimisation or worst-case assessment. The use of surrogate models to
