BackForwardInstrument:  Pléiades-Neo 

Instrument details
Acronym Pléiades-Neo
Full name Pléiades-Neo
Purpose Very-high-resolution land and vegetation observation. Digital Elevation Model (DEM)
Short description Seven VNIR channels, 6 multi-spectral (MS) one panchromatic (PAN) [see detailed characteristics below]
Background Improved after the HiRI instrument flown on Pléiades 1 and 2
Scanning Technique Pushbroom, swath 14 km s.s.p.; cross-track pointing capability by up to ± 30° off-nadir. Stereoscopic capability in-orbit and between successive orbits
Resolution 1.2 m (MS), 0.3 m (PAN), at s.s.p.
Coverage / Cycle Global coverage in 30 days, in daylight. With strategic pointing, one place can be observed every 2 days. The constellation of 4 satellites enables revisit at 12-hour rate.
