Preparation of enabling space technologies and building blocks: Additive Manufacturing for the Space Industry
Background and justification: The use of Additive Manufacturing (AM) technologies in the Space sector is gaining traction, although it is necessary to find new use cases and develop them up to TRL7 or TRL9 to be meaningful The Spanish Space industry has important actors with high knowledge of their products and sector that could benefit from the experience CiTD and CATEC have in AM and improve their products through the use of these technologies  Achievements and status:

Products Evolution for MEO
For a given application area, the power and propulsion requirements may evolve with each generation of the satellite system. Power levels may increase with the enhancement of the payload and also the introduction or the increased use of electric propulsion. These trends are occurring in application segments such as navigation. In order to address these trends, power subsystem solutions may be adapted from satellite systems used for other orbits and other applications.

Automotive FMCW radar technology for space applications
FMCW radar technology in the automotive industry radar market covers 24 GHz and 77 GHz bands with modulated bandwidths of up to 4 GHz, allowing simultaneously ultra-precise determination of target range and its relative velocity. Fine angular resolution with 0.1 deg steps at distance of 300 m and beam-steering capability has been recently demonstrated. FMCW systems have also proved their efficiency for detection of fast-moving objects with small cross-section such as drones.

Technologies and Techniques for SATCOM beyond 5G Networks
In December 2019, the 3GPP standardization group approved a dedicated work-item for the implementation of a new set of 5G New Radio (NR) specifications allowing the integration with mobile broadband satellite networks. This is the first time ever that the space industry has this challenging opportunity of a full integration with terrestrial cellular systems, and to benefit from very large economies of scale.

Cloud Data Processing Service
CDPS envisages to provide cloud capacity for data processing. It offers a cloud-agnostic, highly-scalable framework with resource elasticity, a common component for mission data, and marketplace service for third-party integration. CDPS aims to lower infrastructure costs while providing efficient, scalable, and secure processing capabilities for various Earth Observation systems.

ESA has invested in recent years to improve the security of the software systems by providing a Secure Software Engineering standard along with a number of tools that help developers and technical officers to implement it. The SSE4Space proposal moves the concept one level up to the system engineering domain, where security engineering methodologies and tools are equally important.

GNSS (Global Navigation Satellite System) receiver (such as GPS or Galileo receivers) are vulnerable to RF interference, intentional and un-intentional. Ground GNSS receiver have evolved significantly in the last 10 years to be resilience to such problems. GNSS spaceborne receivers are currently a mission critical element in multiple missions, mainly in LEO orbit, but soon also for GTO and GEO. At the same time the basic architecture adopted does not include (or consider only partially) robustness against RF effects.

Currently, spacecraft operation teams are usually notified of non-nominal conditions when specific system parameters exceed preset threshold values. These out-of-limit (OOL) alarms are reasonably simple in nature, each referring to a single or a set of parameters or conditions, and do not necessarily offer operators a deeper insight into a system?s condition in isolation. ;

Active Battery management
Active battery management is not currently used on ESA missions (apart from reducing End of Charge Voltage during the cruise of deep space missions to increase battery lifetime) but does see some limited use in cubesat programmes. Active battery management is used extensively in terrestrial energy storage. By monitoring the state of charge and voltage of the battery, the power in/out of the battery can be actively managed. This allows several benefits such as sizing a battery more conservatively because different operational modes can be accommodated more easily.

Offline antenna arraying for EnVision
During its science phase EnVision will use ESTRACK antennas located at the three ESA deep space sites in New Norcia (Western Australia), Cebreros (Spain) and Malarg?e (Argentina), and optionally the DSN antennas located at the NASA sites of Canberra (Australia), Robledo (Spain) and Goldstone (United States of America). In order to increase the flexibility in the selection of the ground stations, or alternatively to increase the data volume, offline arraying between distant antennas is proposed during overlapping visibility slots.
