Product Format Compatability with COTS package

The main Data Processing System will accept real time data of multiple streams from data acquisition system. The Radiometric calibration as part of data pre-processing is carried out based on the extensive ground calibration data supported by ground and on-board calibration techniques, which tracks changes in the instrument response due to in-orbit thermo-mechanical environment, radiation effects and aging.

 The geometric correction, re-sampling is performed on the radiometric corrected pixel-data based on static and dynamic models of the instrument and satellite as well as orbit and attitude parameters available simultaneously with the imaging data and produces various levels of data products. A further precision/improved accuracy is necessary which requires in-registering the image-pixels on fixed lat-long grids. It would be achieved through image navigation and registration algorithm in an automatic/interactive approach. The Data Products Software will provide capability for generation of products on the user requested media and in the required format HDF. The various types of products generated by the Data Products System are

  • LEVEL - 0 (Raw) - for internal use and archival
  • LEVEL - 1 (Standard Products)
  • LEVEL - 2 (Geo-Physical Products)
  • LEVEL - 3 (Binned Products)
