What would happen without satellite communications?

Different sectors affected by the loss of satcom

The sudden loss of satellite communications would lead to widespread disruption, affecting vital services such as air travel, maritime logistics and emergency response with an estimated economic impact of up to €20 billion. To highlight the economic importance of satellite-enabled connectivity, London Economics prepared a report for the European Space Agency (ESA), examining the effects of a hypothetical week-long outage of satellite communications across ESA Member States and Canada.

Maritime

Maritime shipping supports the transport of essential goods for manufacturing, energy, food, and retail sectors. The interruption of satellite services would critically disrupt supply chains, affecting not only shipping companies but also related industries such as port operations and warehousing. The projected economic loss is approximately €19 billion, consisting of €3.5 billion in direct impacts and €15.5 billion in indirect effects related mainly to supply-chain logistics.

Aviation

In aviation, lack of satellite connectivity for air traffic management could result in the cancellation or delay of around 4,000 transatlantic flights, leading to approximately 1,800 hours of cumulative delays. The economic loss to the sector is estimated at €558.7 million.

Other sectors

The consequences extend beyond conventional communications. Around 2.2 million individuals in ESA Member States and Canada, particularly those in remote or mountainous regions, would be left without internet access . Emergency messaging systems, which rely on satellites to deliver critical information, would not be able to operate, compromising emergency response capabilities. The economic cost in this area is similar to that of aviation, at around €352.7 million.

The energy sector, particularly offshore drilling platforms operating beyond the reach of ground-based networks, would also be affected, with an estimated economic impact of €89.8 million.
