Magnetic materials, both with soft and hard magnetic behavior, are key components in many devices aboard any spacecraft, such as motors, mechanisms, actuators and sensors. The most common route for the manufacturing of magnets is the sintering process, which produces the highest magnetic performance possible but it is energy intensive and requires molds for each geometry. The alternative is the use of bonded magnets, which are composite materials composed of a polymeric matrix with a high content of magnetic filler.

Achievements and status: ​

The capacity of developing navigation algorithms for data fusion are key aspects covered in SCRIPT. Fusion
navigation solutions based on ranging, direction of departure (DOD) and direction of arrival (DOA) and GNSS based
on single and multiple anchors and peers for outdoor-to-indoor scenarios are developed.
Our own concept in the field of data fusion for indoor/outdoor location, based on a Sigma Point Kalman Filter
(SKPF), the hybrid filter that combines a particle filter with the classical Kalman filter, is used. The SW Receiver

Currently EO missions are operated in S/X-Band with payload data in X-Band. New EO missions will have payload data in K-Band and TTC still in S-Band. In the long term TTC will be moved to X-Band still keeping payload data in K-Band. Presently only US suppliers are able to provide antenna radomes operating over different frequency bands. It is intended to develop an European alternative to US suppliers in the domain of high/multi-frequency application like the one needed for future Earth Observation missions.

Aluminium-based alloys obtained by a rapid solidification process have been successfully used for manufacturing optical mirrors. The maximum size of this type of aluminium mirrors is limited by the size of the billet, i.e. currently considered to be approximately 500 mm with and homogeneous microstructure. Consequently, the current manufacturing processes allow to produce mirrors with an effective area limited to a maximum dimension of 400 mm . The need for larger Aluminium-based mirrors is coming from scientific missions that require a large collecting area.

The Doherty concept has proven to be a very effective technique for designing amplifiers, which maintain a high efficiency over a wide range of operating conditions. This technique is extensively used in terrestrial applications like base stations where power efficiency is getting more and more attention. Power efficiency is also of concern for space and the Doherty concept could certainly help in designing more efficient PAs. Ka-band is now being considered for mobile services that could offer very high capacity as compared to the existing ones at L-band.

The interest of having in the near future an available Position, Navigation and Timing (PNT) service supporting future missions to and at the Moon is currently supported by both institutional and commercial initiatives. On the commercial side, multiple companies are developing business solutions targeting the Moon and several major European companies are proposing to team up to build a communications network on the Moon compatible to terrestrial standards. In parallel, NASA has recently announced its plans to a ?Return to the moon?
