This article has provided an overview of global GPS jamming

and service reduction between 2020 and 2023 using recent

observations from the Spire constellation. The service

power reduction and jamming power increases are highly

correlated on a regional scale, showing that Europe and

the Middle East have been most impacted by the ongoing

geopolitical conflicts. The area of the impacted regions

has widened significantly from 2021 to 2023 and spread

to Northern Europe. The dual-use civil and military GPS

technology and services are currently experiencing an

unprecedented scale of electronic warfare attacks.
