Strange blackouts hits Space satellites near Equator

Researchers have been puzzled by regular blackouts in the GPS navigation system on the European Swarm satellites where DTU Space leads the international scientific cooperation. The loss of signals occurs in particular when the satellites pass the equator between Africa and South-America. The reason is wild space weather.
