Context

CS Group responsabilities for Studies for absolute calibration and MTF measurement of PLEIADES sensors (Star & MOON Methods) are as follows:

• Study, treatments, development

The features are as follows:

• PHR1A & PHR1B Star Calibration:
• Generation of Starpools using the ICC Isatis procedure
• Adding new Starpools to previously used data
• Analysis of new input data: time series trace of the digital count of each star for the Pléiades 1A and 1B Starpools and for different extraction window sizes
• Estimation of absolute and FTM calibration coefficients LUNE PNEO3&PNEO4 calibration:
• Carrying out pre-treatments and calibration treatments for PNEO3&PNEO4
• Evolution of calibration and synthesis tools to refine the analysis of results

Project implementation
