About WorldView-2
WorldView-2 is an imaging and environment-monitoring satellite from Maxar of the United States which launched on 8 October 2009 and remains operational.
It is the follow-on spacecraft to WorldView-1.
| Orbit Altitude | 770 km |
| Orbit Type | Sun-synchronous |
| Orbit Period | 100 minutes |
| Revisit Time | Up to 1.1 days |
| Equator Crossing Time | 10:30 am descending node |
WorldView-2 Objectives
The overall objective is to meet the growing commercial demand for high-resolution satellite imagery. WorldView-2 provides commercially available panchromatic imagery of 0.46 m resolution, and eight-band multispectral imagery with 1.84 m resolution - representing one of the highest available spaceborne resolutions on the market.
WorldView-2 Instruments
WorldView-110 camera (WV110)
This instrument collects images at 0.41 metre panchromatic and 1.64 metre 8-band multi-spectral data. Along with the Pan (450-800 nm) and the four typical multispectral bands (blue, green, red, NIR), WorldView-2 has four additional bands for enhanced multispectral analysis (coastal blue, yellow, red edge, NIR2) designed to improve segmentation and classification of land and aquatic features.
| Imager type | Pushbroom imager (or a line scan imaging system) | |
| Imaging mode | Panchromatic (Pan) | Multispectral (MS) 8 bands (4 standard + 4 additional colors) |
| Spectral range | 450-800 nm | 400-450 nm (coastal blue) 450-510 nm (blue) 510-580 nm (green) 585-625 nm (yellow) 630-690 nm (red) 705-745 nm (red edge) 770-895 nm (NIR1) 860-1040 nm (NIR2) |
| Spatial resolution at nadir | 0.46 m GSD (0.52 m at 20º off-nadir) | 1.8 m GSD (2.4 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)
