ACCESS MISSION DATA

WorldView-3 is the first multi-payload, super-spectral, high-resolution commercial satellite sensor operating at an altitude of 617 km. WorldView-3 is capable of collecting up to 680,000 square km per day.

About WorldView-3

WorldView-3 is an imaging and environment-monitoring satellite from Maxar of the United States which launched on 13 August 2014 and remains operational. It is very similar to WorldView-2 but positioned in a lower orbit.

Mission Parameters
Orbit Altitude 617 km
Orbit Type Sun-synchronous
Orbit Period 97 minutes
Revisit Time 1 day at 1-metre GSD resolution
4.5 days at 20° off-nadir (0.59 m GSD)
Equator Crossing Time 10:30am Descending node

WorldView-3 Objectives

WorldView-3 was the first mission to carry a multi-payload, super-spectral, high-resolution commercial satellite sensor. WorldView-3 is capable of collecting up to 680,000 km2 per day.

WorldView-3 Instruments

WorldView-110 camera (WV110)

This instrument collects images at 0.31 metre panchromatic and 1.24 metre in the eight VNIR bands, 3.7m in the eight SWIR bands and a 30 m resolution in the CAVIS (Clouds, Aerosols, Vapours, Ice and Snow) bands.

WorldView-3 has bands for enhanced multispectral analysis (coastal blue, yellow, red edge, NIR2) designed to improve segmentation and classification of land and aquatic features.

Non-scientific measuring instruments

CAVIS (Clouds, Aerosols, Vapours, Ice, and Snow): The objective of CAVIS is to monitor the atmosphere and provide correction data to improve WorldView-3's high-resolution imagery when it images Earth objects through haze, soot, dust or other obscurants.
