ARTIST RENDERING OF WORLDVIEW-4

WorldView-4

MORE CAPACITY MEANS MORE RELIABILTY

 

WorldView-4 was launched in 2016, making it the newest addition to the constellation. WorldView-4 and WorldView-3 are the only satellites currently in orbit that are capable of delivering true 31 cm resolution, massively increasing our capacity for capturing very high resolution imagery quickly and reliably.
