Customer: Centre National d’Etudes Spatiales (CNES)

Programme: Venμs

Supply Chain: CNES > CS Group SPACE

Context

CS Group responsabilities for Studies for the calibration of VENuS are as follows:

• Study, development, in-flight acceptance support

The features are as follows:

• Improvement of the lunar disk extraction method (Laplace filter)
• Quantification of CT1 and CT2 type residual noise
• Analysis of temporal drift after updating official parameters (PO)
• Saving in calculation time by band-to-band reprojection
• New pixel filtering method
• Improvement of the statistical results file
• Comparison to desert method calibrations
• Analysis of the Moon and Deserts calibration results of a new phase corresponding to a change in altitude

Project implementation

The project objectives are as follows:

• Improve calibrations by sighting the Moon
• Script (SNO method) for its integration into the operational chain (SAG)
• Use of the Moon calibration script for the in-flight recipe after orbit change

The processes for carrying out the project are:

• Study, tests, regular progress updates
