WorldView-4, previously known as GeoEye-2, was a third generation commercial Earth observation satellite launched on 11 November 2016, at 18:30:33 UTC. The spacecraft was operated by DigitalGlobe. With a maximum resolution of 31 cm (12 in), WorldView-4 provided similar imagery as WorldView-3, the highest resolution commercially available at the time of its launch.
The spacecraft suffered a failure in one of its control moment gyroscopes in January 2019, and operations were unable to be recovered. It reentered over New Zealand on 30 November 2021.
