WorldView-2 Instruments
| Imager type | Pushbroom imager (or a line scan imaging system) |
|---|---|
| Imaging mode | Panchromatic (Pan) |
| Spectral range | 450-800 nm |
| Spatial resolution at nadir | 0.46 m GSD (0.52 m at 20º off-nadir) |
| Swath width | 16.4 km (multiple adjoining paths can be imaged in a target area in a single orbit pass due to S/C agility) |

What is WorldView satellite used for?
WorldView-1 is a remote sensing satellite used for providing high-resolution images of Earth. It is the first half-meter resolution commercial imaging satellite in the world to provide imagery of Earth more accurately than its forerunner, the QuickBird satellite.
What is WorldView Legion?
WorldView Legion is a fleet of high-performance satellites that dramatically expands our ability to revisit the most rapidly changing areas on Earth to better inform critical, time-sensitive decisions.
Is worldview 4 still operational?
On 7 January 2019, WorldView-4 was retired when the satellite experienced a failure in its CMGs (Control Moment Gyros), preventing the satellite from collecting imagery due to the loss of an axis of stability.
Where can I buy high resolution satellite images?
The easiest way to buy satellite imagery SpyMeSat provides real-time EO satellite tracking, on-demand access to purchase from leading satellite imagery providers, instant sign-up to our imagery marketplace, and the ability to have a new satellite image taken of any location on Earth.
How do I get high resolution satellite images?
1. Google Earth – Free access to high resolution imagery (satellite and aerial) Google Earth offers free access to some of the highest resolution satellite imagery, although the highest resolution images are actually taken from airplanes. Most of the data on Google Earth was taken in the last 3-4 years.
How do I download high resolution imagery?

How does WorldView-3 work?
WorldView-3 builds upon WorldView-2 and WorldView-1 technology by carrying forward the satellites’ advanced CMGs (Control Moment Gyroscopes). The CMGs, developed at BATC, reorient a satellite over a desired collection area in 4-5 seconds, compared to 30-45 seconds needed for traditional reaction wheels.
How many WorldView satellites are there?
About WorldView Series Owned by MAXAR, the first three satellites in the series are currently operational, and they have been supplying imagery since 2007. WorldView-2 launched in 2009, as a follow-on spacecraft to WorldView-1.
How much does a maxar satellite cost?
Overall, the delays of WorldView Legion that have pushed the constellation deployment from 2021 to the second half of 2022 are adding $60 million in costs to the satellite fleet’s development, the company said. That’s pushed WorldView Legion’s overall development costs to about $700 million, Porter said.
Can satellites be repaired?
Satellites like the Hubble Telescope and the International Space Station, which are of great scientific value, are repaired if they become damaged in any manner. Take the ISS, for example; it’s actually a space laboratory that consistently hosts a few astronauts and researchers.
What is the resolution of WorldView-2 images?
WorldView-2 operates at an altitude of 770 kilometers, and the advanced on-board imaging system can capture pan-sharpened, multispectral images (with better than 0.46-meter resolution) from almost 500 miles above the earth.
How to change image resolution online?
You can easily resize online on this best image resolution changer tool. For changing resolution, you have to select image that you want to resize on this tool. After selecting image on this tool, you can see there this tool will automatically start changing resolution and then display a new size as well.
How does WorldView-2 work?
With its improved agility, WorldView-2 is able to act like a paintbrush, sweeping back and forth to collect very large areas of multispectral imagery in a single pass. WorldView-2 alone is able to collect nearly 1 million km2 every day, doubling the collection capacity of our constellation to nearly 2 million km2 per day.
How many colors are in the WorldView-2 sensor?
The WorldView-2 sensor provides a high resolution panchromatic band and eight (8) multispectral bands; four (4) standard colors (red, green, blue, and near-infrared 1) and four (4) new bands (coastal, yellow, red edge, and near-infrared 2), full-color images for enhanced spectral analysis,…
