WORLDVIEW-2
data sheet
WorldView-2
WorldView-2, launched October 2009, is the first high-resolution 8-band
multispectral commercial satellite. Operating at an altitude of 770
km, WorldView-2 provides 46 cm panchromatic resolution and 1.85 m
multispectral resolution. WorldView-2 has an average revisit time of 1.1 days
and is capable of collecting up to 1 million sq km of 8-band imagery per day,
greatly enhancing Maxar’s multispectral collection capacity for more rapid
and reliable collection. WorldView-2 substantially expands imagery product
offerings to all Maxar customers.
