EnVision on-ground data processing and products

Data downlink and on-gRound data processing

The measurements by the EnVision instruments and experiment in Venus orbit, are down-linked to Earth where the data are further calibrated and processed to yield the geophysical data products. The data processing is done by the respective instrument teams, and sent to the ESA Planetary Science Archive (PSA) for storage and public data access.
