From now on, its waves will travel towards our naturalsatellite, using a novel method: trans-ionospheric propagation, which consists in crossing the ionosphere, this time using the waves of highest frequencies of the HF spectrum... The results obtained from the first experiment were satisfactory and the Earth's naturalsatellite was indeed detected
Electronic components are subject to natural radiation that could harm them or create false information, especially at altitude. ONERA assesses the damage, to improve the reliability of satellites or aircraft... The kind of risk that satellite manufacturers take into account as from the design... Satellites and aircraft are therefore particularly exposed to it
