Enabling effective communication for human space exploration beyond Low Earth Orbit

Communication between crew and ground on future deep space missions will be impacted by communication delay (signal latency), caused by the finite speed of light and radio waves across great distances. The one-way latency caused by the distance between the Earth and the Moon is about 1.3 seconds. The actual latency at lunar distances during the forthcoming Artemis missions is expected to be even higher due to the various signal processing steps associated with the digital communication protocols. Estimates currently vary up to 10 seconds one way.

High Power W-Band TWT

The millimeter wave domain is also known as the extremely high-frequency (EHF) spectrum ranges from 30 to 300 GHz. Early works on atmospheric propagation in EHF evidenced encouraging future usage for satellite communications. The allocated W-band for satellite services (71-76 GHz and 81-86 GHz) seems to provide a favourable attenuation window related to oxygen absorption. The exploitation of W-band may offer many advantages for wireless communications, which make it suitable for satellite links, such as: broad bandwidths for high data rate information transfer (e.g.

Underwater VR for astronaut training

This research integrates a complete diving mask with a custom-made VR headset to replicate a space-like setting. Alongside designing and building a waterproof VR headset, a pivotal aspect involves implementing a tracking system to ascertain spatial positioning and orientation. Employing an external tracking system, comprising four cameras housed underwater and affixed to aluminum rails this is achieved using fiducial markers.

Reusing Automotive Certification and Qualification Standards

The ASIL2ECSS ESA-funded activity aims to reduce the space qualification cost by reusing hardware and software developed for the automotive domain, which complies with the ISO 26262 functional safety standard. In order to do so, ASIL2ECSS created a mapping between the various ECSS standards and ISO 26262 and related automotive standards in a structured way.

Fast Reconfiguration Technologies for Recurrent Space Transportation Flight

Currently extensive mission preparation / mission customisation ("missionisation") activities are required for each specific launch trajectory. This approach is costly and each launch can take place only within a narrow set of conditions (e.g. wind) risking postponement, increasing cost even further. Using a more aircraft like approach with guidance and control preparation according to flight envelope not per trajectory, while increasing operational availability and safety early in the development process is essential to achieve the benefits of recurrent space transportation flight.

Software product assurance for autonomous on-board software

The presence of autonomous software systems as well as artificial intelligence components in onboard software is becoming increasingly widespread in space missions. As autonomous software is finding its way into more and more missions, having a unified approach for the product assurance of this type of software that can be made applicable across projects is essential.Many of the software product assurance requirements currently in place for space missions could be impacted by autonomous software, from fundamental topics like criticality analysis, down to detailed software quality metrics.

Proof-of-concept of a space-based position augmentation with 2way communication
Passive ranging relying on broadcast signaling is very attractive in terms of scalability, and allows to provide passive ranging capabilities to billions of users worldwide with 24 medium earth orbit satellites. Passive ranging rely on the fundamental assumption that the observed propagation delay relates to the geometric range. This is acceptable mainly under benign conditions.

High accuracy testing of interferometric antenna with large baseline

Future high frequency interferometric antennas (e.g. at Ka band) using large baselines require verification and testing with a very high accuracy, in particular in phase. While such interferometric testing and ground calibration techniques have been successfully performed in the past (i.e.
