Study on millimeter wave GaN transistors for space applications

GaN-based devices are becoming a key technology for millimeter-wave applications. Because of outstanding material properties, recent advances in GaN device designs provided a sharp increase in performances including high power, high efficiency, reliability, linearity, and compact size. These capabilities are ideally suited for numerous millimeter-wave power applications such as wireless networks and PAs MMIC for Q-band frequency and beyond.

Intelligent COTS based Power Stages for Robotic Applications

The main objective of the intelligent COTS-based Power Stages (iCOTS) project consisted of the following aspects:

  • Design and implementation of a BLDC power stage for robotic space application
  • A modular design for the evaluation of power electronics in robotic space application based on COTS GaN-FETs
  • Definition of the design process and the appropriate selection of COTS components
  • Radiation test of selected COTS components

Magnetic Shields for Quantum Sensors in Space

The activity investigated a novel hybrid magnetic shielding system that uses both passive and active cancelation. The design and simulations used, along with the characterisation and measurements taken on the optimised system, are summarised in the executive summary report, and described in more detail in the Final Report. This activity was divided in two main work packages: study of optimisation and magnetic shield prototype.

Sub nano-g MEMS accelerometer for high precision orbital manoeuvres

The inertial navigation market has a need for accelerometers with high sensitivity, low noise, low cost and low power consumption. ESA has identified high accuracy accelerometer units as a priority in a 2019 roadmap. The current state of art products are not able to deliver. Here we introduce a novel accelerometer design, using concepts originally developed for gravitational wave detector physics, which will enable an accelerometer to meet these requirements.

European EEE-Component landscape analysis

Electrical, Electronic and Electro-mechanical (EEE) components play an essential role in the functional performance, quality, life cycle and costs of space systems. EEE components are fundamental building blocks of any spacecraft and major drivers in determining their performances. Guaranteeing access to EEE components able to provide the necessary performances to comply with the requirements of future satellite missions is of paramount importance to maintain a successful and autonomous satellite manufacturing capabilities.
