Context

CS Group responsabilities for Studies for absolute calibration and FTM measurement of Pleiades sensors (Star & Moon methods) are as follows:

• Study, treatments, development

The features are as follows:

• Phr1a & phr1b stalking stalks:
• Generation of starpools using the ICC Isatis procedure
• Addition of new Starpools to previously used data
• Analysis of new input data: trace of time series of the digital account of each star for Starpools Pléiades 1A and 1B and for different sizes of extraction windows
• Estimation of absolute calibration coefficients and FTM Pneo3 & pneo4 moon stalker:
• Realization of pre-working and calibration treatments for pneo3 & pneo4
• Evolution of calibration and synthesis tools to refine the analysis of the results

Project implementation

The project objectives are as follows:
