ers pect ral ▁Mission ▁( J H M ). ▁ ▁Pay load ▁The ▁Hyp ers pect ral ▁/ ▁Pan chrom atic ▁payload ▁is ▁derived ▁from ▁Hyp SE O ▁and ▁updated ▁as ▁for ▁the ▁J H M ▁study : ▁ ▁PR IS MA ▁( H yp ers pect ral ▁and ▁Pan chrom atic ▁instrument ): ▁a ▁pr ism ▁spect rom eter ▁composed ▁of ▁the ▁Hyp / Pan ▁camera , ▁an ▁optical ▁head ▁and ▁the ▁main ▁electron ics ▁box . ▁The ▁design ▁is ▁based ▁on ▁a ▁push bro om ▁type ▁observation ▁concept ▁providing ▁hyp ers pect ral ▁imag ery ▁( ~ ▁ 2 5 0 ▁bands ) ▁at ▁a ▁spatial ▁resolution ▁of ▁ 3 0 ▁m ▁on ▁a ▁sw ath ▁of ▁ 3 0   km . ▁The ▁spectral ▁resolution ▁is ▁better ▁than ▁ 1 2   nm ▁in ▁a ▁spectral ▁range ▁of ▁ 4 0 0 - 2 5 0 0   nm ▁( V N IR ▁and ▁SW IR ▁regions ). ▁In ▁parallel , ▁Pan ▁( P anch rom atic ) ▁imag ery ▁is ▁provided ▁at ▁a ▁spatial ▁resolution ▁of ▁ 5 ▁m ; ▁the ▁Pan ▁data ▁is ▁co - register ed ▁with ▁the ▁Hyp ▁( H yp ers pect ral ) ▁data ▁to ▁permit ▁testing ▁of ▁image ▁fusion ▁techniques . ▁ ▁In ternal ▁Cal ibration ▁Unit ▁( IC U ): ▁an ▁instrument ▁designed ▁to ▁allow ▁the ▁support ▁of ▁absolute ▁and ▁relative ▁radi ometric ▁cal ibr ations ▁and ▁spectral ▁cal ibr ations . ▁ ▁Pay load ▁Data ▁Hand ling ▁and ▁Trans mission :
