RSI  

Definition

  • RSI is a pushbroom-type imager built by EADS Astrium SAS, France. RSI is made up of the camera and IPU (Instrument Processing Unit). The camera itself consists of the optical subassembly, the secondary structure, and the FPA (Focal Plane Assembly). The Korsch telescope (mirrors & structure) design and the focal plane structure are being made of SiC (Silicon Carbide). The video electronics, sequencer, DC/DC converter, and compression cards comprise the IPU. 27) 28) 29) 30) Spectral bands: 1 PAN (Panchromatic band) 4 MS (Multispectral bands), nm 450-900 nm B1= 450-520, blue B2 = 520-600, green B3 = 630-690, red B4 = 760-900, NIR Spatial resolution (GSD) 2 m for PAN, 8 m for MS imagery Swath width 24 km S/C body pointing capability, FOR (Field of Regard) ±45º in the roll and pitch axis ( providing a cross-track observation capability of 968 km about nadir for event/disaster monitoring); cross-track and along-track observation capability Optics, focal length, Aperture diameter Cassegrain type optics with refractive corrector, focal length= 2896 mm, pupil diameter = 600 mm Detector types CCD: TH 7834 for PAN, THX 31547 quad-linear CCD for MS Pan: 12,000 pixels, MS: 3,000 pixels Integration time 0.308 ms for PAN, 1.232 ms for MS Processing rate 10 Mpixel/s for PAN, 5 Mpixel/s for MS Pixel quantization 12 bit Data compression ratio 2.8 and 3.75 for PAN, 1.7 and 3.75 for MS Instrument mass, power consumption 114 kg, 161 W for imaging, 73 W for standby (en)
