PLEIADES vs. competitors: technical assets
Mission A constellation of 2 identical Pleiades satellites ensuring daily revisit of any
point of the globe Continuity of service : beyond 2018 Dual mission but…95% of satellite data for worldwide end-users
50% for GE-1, 15-30% for WV1…
Imaging capacity Large imaging capacity: 500,000km2 /day /satellite (roll<30°) Scene size 20 x 20 km with GSD 0.7m vs. 15x15 km with 0.5m for GE or 17 x17
for WV Permanent Pan + XS imaging mode, no « slowdown » Agility: very large mono-pass capacity
Pleiades more agile than GE-1(x2), same as WV Tri-stereo
Services High level of reliability and operationality ( SPOT legacy) Mosaic , pan-sharpened and 3D products as output of standard PHR archiving
