WorldView Legion is the next evolution of Maxar’s industry leading WorldView constellation. The 6-satellite fleet will be launched during late 2021 and throughout 2022.
One of the key features of this new constellation is the ability to dramatically expand revisits over some of Earth’s rapidly changing regions. With revisits of up to 15 times per day it will triple Maxar’s current capacity to collect high resolution 30cm imagery. This greatly increases the ability to better inform critical and time sensitive decisions.
The high-performance satellites will also enable stereo capabilities for 50cm DEM (Digital Elevation Models) and allow for the most advanced geospatial analytics.
This advanced constellation will provide the highest levels of commercial use imagery with accurate and high-agility point collects which can be utilised for mapping projects, large area collection zones, monitoring targets for near real-time change detection.
Features and Benefits
- 30cm high resolution imagery.
- The WorldView Legion satellites will have 8 multispectral bands – fantastic for spectral analysis and machine learning.
- Rapid mid-inclination orbits over fast changing regions.
- 50cm Digital Elevation Models (DEM) with stereo capability.
- Advanced accuracy and detailed imagery for commercial and government use cases.
- Has a swatch width of 9km at nadir.
