The word avionics is a contraction of 'aviation electronics', referring to the data handling sub-system, guidance navigation and control devices and associated software flown aboard a satellite.
These facilities focus on assessing the performance of antennas and support testing across the entire spectrum of antenna development: from characterising the properties of the materials to the validation of full-scale radiating systems
The EMC laboratory comprises several facilities dedicated to characterise magnetic properties of parts and ensure different electrical systems can operate together without interference.
Satellites have one characteristic in common: they all have to reach out beyond themselves either to receive commands, relay telecommunications, perform remote sensing or deliver precision navigation and timing data. These laboratories perform Radio Frequency research for both the space and ground segments.
Satellite systems rely on electricity to keep operational, but their power subsystems require careful design and management. The level of power produced by solar arrays – the dominant electricity source for almost all missions – varies greatly over time depending on satellite and planetary motion and short- and long-term space environment effects.
