DigitalGlobe’s WorldView-3 Launches Successfully

On August 13, 2014, DigitalGlobe successfully sent the next-generation high-resolution imagery satellite into space, WorldView-3 (WV3). WorldView-3 joins its two siblings, WorldView-1 and WorldView-2 (WV2), orbiting our planet a mere 617 kilometers from its surface! DigitalGlobe has set a track record of calibrating satellites quicker than any other company in the industry, so we fully expect WV3 imagery sales to start before the end of 2014.

Hands down, WorldView-3 is the most technologically advanced satellite ever launched. Building upon and extending the technology of WV2, WorldView-3 features higher resolution, more spectral bands and greater agility than any other commercial satellite in the marketplace.

Here are the features that really set WV3 apart from the competition:

WV-3-Launch-Sequence-T+17-to-T+95-900x600As WV3 sped through our atmosphere reaching an orbit more than 600 km above the planet, its 50-cm panchromatic-only sibling, WV1, captured this time series of the launch from its heavenly position.
  • Improved Resolution
    • Higher resolution means you can see more detail in WV3 imagery.
    • Data collected at nadir will have 31-centimeter (cm) panchromatic, 1.24-meter (m) visible and near infrared, 3.7-m short-wave infrared and 30-m CAVIS bands.
    • At 20 degrees off-nadir, the resolution is 34-cm panchromatic, 1.38-m visible and near infrared and 4.1-m short-wave infrared.
    • With the easing of US government regulations, we will be able to provide WV3 imagery at a maximum of 30-cm resolution.
  • Additional Spectral Bands
    • If spectral analysis is part of your project, then no other satellite can match WV3 with its 8 bands of visible and near-infrared data; 8 shortwave infrared bands which are crucial for geological studies; and 12 CAVIS bands to detect water vapor, dissolved aerosols, snow, clouds and more.
  • Better Positional Accuracy
    • With accuracies of 3.5-m CE90% or better (without ground control even!), WV3 has no rivals for its enhanced positional accuracy.
  • Daily Revisits
    • At 40 degrees latitude, WV3 will be able to image each location daily with 1-meter or better resolution and then every 4.5 days at 34-cm resolution or better.
  • Increased Collection Capacity
    • WV3 features a 13.1-km swath width (at nadir) with the ability to collect up to 680,000 square kilometer (sq km) of high-resolution data per day.
    • Improved control movement gyros translate into a larger maximum contiguous collection area per pass with up to ~7,500 sq km of mono imagery and ~3,000 sq km of stereo possible.
