Instrument details
Acronym HRSAT-1
Full name High Resolution Satellite - 1
Purpose High resolution land observation
Short description Information only partially available. It should iinclude a panchromatic channel (PAN), a VIS/NIR multispectral radiometer (MX, presumably 4 channels), and a so-called LWIR channel, presumably in MWIR.
Background New development
Scanning Technique Push-broom, swath 15 km (PAN and MX), 6 km (LWIR). Addressable within a field-of-regard of 400 km
Resolution 1 m (PAN, 4 m (MX), 20 m (LWIR)
Coverage / Cycle Depending on pointing strategy. Minimum I day, in daylight
Mass Power Data Rate
