BackForwardInstrument:  LISS-4 

Instrument details
Acronym LISS-4
Full name Linear Imaging Self-Scanning Sensor - 4
Purpose Very-high-resolution land and vegetation observation
Short description 3-channel VIS/NIR radiometer, one camera each channel [see detailed characteristic below]
Background Complementary to LISS-3 on ResourceSat-1 and ResourceSat-2
Scanning Technique Pushbroom, 4096 pixel/line per camera; swath 23.9 km if the 3 cameras are used each for 1 different channel (thus multi-spectral), or 70 km if all cameras are used for viewing parallel strips in the same channel (thus panchromatic).  Cross-track pointing capability ± 26° for stereoscopy in between orbits
Resolution 5.8 m
Coverage / Cycle Global coverage in 24 days, in daylight.  5 days for a target area by using cross-track pointing
Mass 133 kg Power 129 W Data Rate 294 Mbps
