Satellite communication, or SatCom for short, is the technology that sends information via satellites orbiting the Earth. It underpins everything from internet access to phone communication – and plays a big role in military operations. Heinrich Krispler, project officer for Govsatcom and support to EU operations, reveals how Europe is using this technology to bolster security and support the military, for example, in Ukraine. Meanwhile, Holger Lueschow, who works closely with Heinrich, highlights how EU governments use SatCom, and explores ambitious new projects such as IRIS², the EU’s forthcoming satellite constellation.
