WorldView-3 – DigtialGlobe’s Newest Satellite
DigitalGlobe will soon be launching its newest satellite, WorldView-3 (WV-3), into orbit. The craft was designed by Ball Aerospace with imaging sensors built by ITT Exelis. Once placed into orbit, WV-3 is expected to have a service life of 10 to 12 years.
Lockheed Martin Commercial Launch Services will take charge of the launch from Vandenberg Air Force Base in California on August 13, 2014. Within six months of its launch, mid-February 2015, WV-3 imagery will be available for commercial sale in a range of resolutions and bands.
- 31cm Panchromatic
- 1.24m 8-Band Multispectral
- Red, red edge, coastal, blue, green, yellow, near-IR1 and near-IR2
- 3.7m 8-Band SWIR – Short-wave Infrared
- For The First Time
- 30m 12-Band CAVIS – Cloud, Aerosol, Vapor, Ice, Snow
- Desert clouds, aerosol-1, 2, & 3, green, water 1, 2, & 3, NDVI-SWIR, cirrus, snow
- CAVIS will provide data to correct imagery that is captured through haze, fog, dust, smoke and other air-born particles
WorldView-3 will orbit the Earth at an altitude of 617km, allowing it to capture imagery at a resolution of 31cm. Following the newest resolution relaxation ruling from the Department of Commerce earlier this month which allows commercial sale of 25 cm resolution imagery, WV-3’s orbiting elevation may be revised to allow the sensor to capture imagery at this higher resolution. With a swath width of 13.1km, WorldView-3 will have the ability to capture up to 680,000 sqkm of imagery every day.
An exciting new technology, Control Moment Gyroscopes or CMGs, has been developed specifically for WV-3 by Ball Aerospace. The CGMs will be able to reorient the satellite over a chosen location in as little as 4-5 seconds; much faster than the 30-45 seconds needed for traditional reaction wheels.
Within the ever evolving world of satellite imagery, DigitalGlobe is constantly moving forward to bring its customers the best possible products and services. The introduction of WV-3 into the constellation of sensors already orbiting the globe will bring exciting, new possibilities to the industry. eMap International, in partnership with DigitalGlobe, looks forward to being able to help you realize those possibilities.
