CEOS Instrument: HRG




Instrument:HRG
Agency: CNES
Mission: SPOT-5
Status:Operational
Type:High resolution optical imager
Description:High resolution multispectral mapper. 2 HRG instruments on this mission can be processed to produce simulated imagery of 2.5 m. Images are 60 x 60 km in size
Spatial Resolution: Panchromatic: 5 m, Multispectral: 10 m
Swath Width: 60 km (1 instrument), 117 km (2 instruments). Same as SPOT 4 with off-track steering capability (▒27 deg)
Wavebands: VIS: B1: 0.50 - 0.59 ?m, B2: 0.61 - 0.68 ?m, NIR: B3: 0.79 - 0.89 ?m, SWIR: 1.50 - 1.75 ?m, Panchromatic: 0.49 - 0.69 ?m
Technology: High resolution optical imager
Description: Imaging Vis/IR radiometer whose characteristics are stressed towards spatial resolution (typically <30 m). Spectral coverage in bands of Vis and NIR (0.4-1.3 Ám). Number of channels can be small (extreme: one, i.e. panchromatic) or very large (hyperspectral) separated in-field (array detectors) or by a spectrometer, or a combination of both. Channel bandwidths from 0.5 Ám (PAN) to 5 nm (hyperspectral). Applicable only in LEO.
