  • High Voltage Switching Matrix

    In Electric Propulsion systems often cross-switching of high voltage lines is required. Nowadays this kind of switching is usually done with high voltage relays. Benefits are expected by replacing the relays with semiconductors. The challenge will be the use of advanced semiconductors capable to deal with high voltages, related to Hall Effect...

  • Ka-band radio characterisation for SatCom...

    Satellite services in the High North are utilised extensively for both communication purposes and for earth and climate observations. The project results are based on up to three year measurements at 20 GHz with co-sited meteorological data. They suggest that services can be provided with 99 % availability for systems with elevation angles as low...

  • MEMS FCM for EP

    The objective of this project was to design, build and test an engineering model of a Xenon Flow Control Module using MEMSbased flow control elements. The primary application for this MEMSbased Xenon flow controller module is existing and future medium and high power Electric Propulsion thruster applications.

  • KHT - Krypton Hall Thrusters

    Starting from an existing EP technology to be potentially employed for Next Generation Telecom Platforms, the effects on both thruster and system-level performance of propellants selected to be potentially alternative to Xe have been assessed through the development of mathematical models and dedicated test sessions.

  • D2RF

    The output of the current generation of digital processors, used on commercial satellite missions, is either at baseband, or a low IF. This signal must then be up-converted to the operating frequency of the spacecraft, such as C, Ku or Ka-band. The need for these up-converters significantly increases the cost per output of digitally processed...

  • Broadband Linearisers (BLIN)

    As the key nonlinear building block of a linearized channel amplifier (LCAMP) the linearizer must compensate a broad variety of TWT nonlinearities. A set of new RF equalizer MMICs provides a greater tuning flexibility by electronic means, thus making hardware modifications obsolete.
