description WorldView-4 Overview
WorldView-4 was a commercial Earth-observation satellite operated by DigitalGlobe, the company later absorbed into Maxar. Launched in 2016, it collected high-resolution imagery from a polar, sun-synchronous orbit and was designed to provide panchromatic images with a ground sampling distance of about 0.31 metres. A failure of its control-moment gyroscopes in 2019 ended the spacecraft's imaging mission, permanently removing it from operational service.
help WorldView-4 FAQ
What was WorldView-4 used for?

When was WorldView-4 launched?
WorldView-4 launched in 2016. It operated from a polar, sun-synchronous orbit designed for consistent Earth imaging.
How detailed were WorldView-4 images?
Its panchromatic imaging was designed for roughly 31-centimeter ground sampling. That allowed individual buildings, roads, and other large objects to be mapped in considerable detail.
What happened to WorldView-4?
WorldView-4 stopped producing imagery after a spacecraft anomaly in 2019. The satellite was later declared non-operational, while Maxar continued operating other Earth-imaging satellites.
