Can anyone tell me the process for geocoing of sentinel 2 data

Can anyone tell me the process for geocoding of sentinel 2 data. And how to match the resolution of sentinel 1 and sentinel 2 product.

Sentinel-2 data is already geocoded. They are provided in a UTM reference system.

To bring S1 and S2 data in the same resolution you can use the resampling tool. Or you collocate both with the Collocation tool.
