Sentinel-1 & Sentinel-2 Missions
Phase A-D : Feasibility + preliminary definition to detailed definition and production
Emissions will be estimated by
Has an LCA been carried or phases of an LCA for Sentinel 1 and 2 ?
No
Which Satellite that has had an LCA done can be compared to Sentinel 1 and 2 ?
Yes
Which satellite ? How are they similar ? How the we get the information ? Which phase is comparable ? An allocation key will be used to estimate the emissions of the satellites
Price or/and weights - OK

What is the cost of the Sentinel 1 and 2 missions (per phase) ?
No
1 more item...
Astra 1N - not similar, Proba 1 - maybe, MetOp A - maybe, Sentinel 3B - similar

How many PB are exchanged between Antennas and Clouds? (3-3,5 PB)
How many PB (petabytes) were exchanged between the Satellites and the Antennas in 2019? In other years? (In 2017, we found a value of 2.5 - 3 PB per year).
General questions
Where can ESA see how much data is being exchanged and/or the calculation power? Do you have access to this information? If not, do you know who has access to this information?
For what application is the data being collected?
What kind of information can be gathered for the data? Until which stage?
How do the DIAS and GAFAM use the data collected by Sentinel-1 and Sentinel-2? How can we extrapolate the data from the DIAS to the GAFAM?
EDRS
