A significant level of commonality has been achieved across ESA missions belonging to the same category. This applies to the space segment (e.g. Generic platforms, reference architectures), to the ground segment (e.g. Generic solutions for ground data systems, shared space-ground communication network) and to the space-ground interfaces (e.g. Communication, protocol and service level standards).

GNSS users seek better position estimates; this means high precision and shorter times to achieve low error positions. In addition, the number of GNSS receivers, both single or multi-frequency and/or multi-constellation are growing and an increasing number of applications and services rely on these estimates. In this framework, the development of the Fast Precise Point Position and similar algorithms seem to cover the need for faster (low convergence time) and more precise position estimates in Real-Time (RT).

Increasing system complexity introduces challenges for aggregation, integration and configuration of a system of systems. This leads to test cases proliferation to ensure test coverage and effort increase to support tests definition, execution and results analysis. Under time and cost pressure, incomplete test coverage endangers mission functional and security aspects. Artificial Intelligence can enhance existing ground segment test automation frameworks e.g.

Security is becoming increasingly important in all of ESA's missions, rather than just in specific missions (Galileo, Copernicus) as was the case in the past. Therefore, the European space industry need to have a well-defined and standardized approach to assess the security processes of its suppliers, especially in terms of software development, where many security vulnerabilities can be introduced.

The objective of the SysAOCS project was to investigate the use of SysML to digitalize the AOCS/GNC description. The project started in February 2022 and was organized into 4 tasks running for a total duration of 1 year. The first task was devoted to the investigation of previous related activities and the selection of two study cases. Among the different SysML methodologies, the SysML ESA Solution was selected and used to build a dedicated AOCS/GNC profile.

Several developments are on-going and targeting an accuracy above 10 bits, however no development and no product in the market is currently covering low accuracy. There is a clear need for this type of sensors as for many applications that need low or medium accuracy sensors, cost is normally an important factor. To fit this type of applications, current mechanisms use potentiometers, which are easy to integrate and cheap compared to other products, however, they are prone to noise and limited life because of their technology, based on sliding electrical contact.

As proved in several missions, the Lorentz force acting on the electric current carried by a space electrodynamic tether (EDT) can be used to propel spacecraft without using propellant. State-of-the-art EDTs involve a bare tape for passive electron collection (anodic contact) and an active device, or a tether segment coated with a low-work-function material, for electron emission (cathodic contact).
