WorldView – 4

WorldView-4 is the newest sensor in Digital Globe constellation which mission started in 2016. The  orbit of satellite was 617 km, resulting in imagery with resolution of 0.31 m (panchromatic) and 1.24 (multispectral). The combination of data from WorldView-3 and WordlView-4 gives the opportunity to image an area of interest every 4.5 times a day.

Unfortunately, on January 2019, Maxar (parent company of Digital Globe) announced a failure in the satellite’s control moment gyros and is not recoverable nor producing viable imagery.
