SIDLOC (Spacecraft Identification and Localization) is a new transmission scheme proposed by Libre Space Foundation to enable LEO satellite identification and tracking. The SIDLOC system relies on a reduced size autonomous transmitter that requires minimal integration and area on the carrier spacecraft. The ground segment of the SIDLOC system utilizes the existing SatNOGS network and the UHF band to perform the signal demodulation and identification. The SIDLOC system uses DSSS (Direct Sequence Spread Spectrum) PSK modulated signals with an effective bitrate of ~50 bits/s.

This project aim was to make steps towards a demonstrator for a fully stabilized frequency comb, with the ultimate goal of creating a space-grade version. Such a system is essential for advancing timing and frequency distribution in space technology and enhancing Galileo satellites. Transitioning from electronics to photonics promises to significantly boost the accuracy and precision of satellite clocks, leading to heightened data transfer security, improved telecom performance, resistance to jamming, and more accurate greenhouse gases detection.

Several SAR future Earth Observation missions requires large reflector antennas generating highly directive overlapped beams. This has been done so far with high power waveguide Beam Forming Networks including ferrite switches as implemented for Core H2O pre-developments. In this activity, it is proposed to investigate reflector antennas fed by overlapped subarrays. This represents an extremely promising concept for on-board SAR instruments.

Optical phase beam steering enables motionless pointing of light. The lack of mechanical moving parts not only reduces overall Mass, Volume, and Power (MVP) to a fraction of conventional solutions, but also reduces the associated risk due to friction fatigue. The applications of this technology both on Earth and in Space are only beginning to be fully understood and realised.

In recent years, advances in Internet-of-Things (IoT) makes it easy to apply sensors at distributed applications like smart farming. However, scaling to large areas is possible but cumbersome. Another possibility is to acquire earth observation (EO) data from satellites which scales easily for large areas and even global wide monitoring. However, satellite data is not available continuously for a certain place and specific data is not available in case of clouds.

Development of deep-space optical communication systems (DOCS) poses a number of technical challenges as compared to conventional radio-frequency links. The higher energy of a single quantum (a photon) at the optical carrier frequency implies the need for dedicated modulation formats and receiver designs. The current technical standard for efficient DOCS is pulse position modulation (PPM) format combined with direct detection (DD) which for photon-starved links is implemented as photon counting.

Passive intermodulation is a real threat to all types of payloads. In some cases, it could even lead to total lost of the spaceship. Despite of this, there is very weak understanding of the parameters that generate this unwanted interference as well as their influence in the amplitude of the interfering signal. In addition, there is a total lack of agreed testing techniques, procedures and methodologies as well as justified test margins, as has already been recently stated by the European community (National Delegations, satellite operators and Eurospace).

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?
