This Auroral Oval Monitoring (AOM) Phase A study was a reorientation after the previous Phase AB1, with a simplified payload prioritizing auroral observation and a complete redesign of the mission. The first part of the study was to update the mission architecture with an affordable, sustainable, and scalable solution resulting in a Mission Definition Review (MDR).

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.

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.

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.

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.

This study investigates Direct Sun Reflecting solution, an innovative concept aiming at boosting energy producing while optimizing existing structures utilization and maximizing their returns. It addresses the pressing need for sustainable energy solutions that can pave the way towards a greener and more resilient future and aligns with Europe's commitment to achieving net-zero emissions by 2050. Our concept is based on the global concept of Space Based Solar Power infrastructure and aims at producing green energy in the fastest time to market and the most competitive cost.

The growth of the human population, industrialization of developing countries and rising living standards for the population are continuously increasing global energy demand, that in the next 30 years is forecast to double.
