On 11 November 2016, Maxar’s WorldView-4 was launched from Vandenberg Air Force Base in California, joining WorldView 1, 2 & 3.
WorldView-4 allows you to differentiate between objects with far greater accuracy and set a new standard for commercial satellites in-orbit. WorldView-4 offers unique opportunities in fields such as environmental assessment, marine studies, natural resource exploration, vegetation classification, coastal management, mining, monitoring land use and many other applications.
The satellite has been decommissioned due to a mechanical failure on one of the control moment gyroscopes which occurred in 2019. However archive data is highly valuable and currently used on various applications.
Features and Benefits
- Currently still used for high resolution archive data.
- Has a swath width of 13.1 km at nadir.
- Provides detailed insights with 30cm resolution capability.
