EOSOL Aerospace Develops an Omnidirectional Antenna for the ESA's A4UC Project

Not the Moon but almost… measurements done in real scenario ensure good performance of 2.4GHz Antenna and a complete comms system.

In the frame of the European Space Agency (ESA) project A4UC (Antennas for Underground Communications), EOSOL Aerospace continues to work on the development of antennas and connectivity solutions to enable lunar exploration.

Within the A4UC project of the European Space Agency – ESA, led by Universidad de Oviedo and in collaboration with Universidad de Vigo, EOSOL Aerospace has developed the 2.4GHz omnidirectional antenna for the communications module. The antenna together with the radome that protects it from the harsh lunar environment has been manufactured and validated to TRL6.

Following the antenna qualification campaign. Last week the project team formed by the University of Oviedo, the University of Vigo and EOSOL, together with personnel from the European Space Agency (ESA) carried out a test campaign in La Corona volcanic tube in the Canary Islands (Spain), simulating a lunar environment. The results obtained were satisfactory and have allowed the complete communications system to be validated.

EOSOL Aerospace continues to develop new antenna solutions in both S-band and C-band for lunar connectivity.

The moon is waiting for us!

About Universidad de Oviedo

Universidad de Oviedo has a broad experience in conducting R&D projects funded by national and international public agencies and industry. University of Oviedo were involved in the project RoboCrane for wireless power and data transmission between surface and cave” and in the “Lunar Caves CDF study”. Robocrane were selected, together with other four ideas, from the Sysnova Lunar Caves Challenge and it was funded in May 2020. Two of the selected teams, Robocrane and Daedalus were integrated into the ESA Lunar Caves CDF study as external consortia.

About Universidad de Vigo

University of Vigo has participated in several projects in the development of space missions with small satellites, and in recent years, in lunar exploration technologies as well. The Aerospace Technologies Research Group and the COM Group, both part of the AtlanTTic research center have provided systems engineering in lunar missions for the European Space Agency, as well as the validation of subsystems and adaptation to space conditions. This allows for resistance to all types of environments, from the vibrations experienced by the equipment inside rockets to qualification in thermovacuum conditions, as well as thermal analysis of these subsystems, both in lunar missions and in the example of the antenna developed in the ESA “Antennas for Underground Communications” project, as well as in small satellites.
