Hello all, as we know , Landsat8 has the orbit number path and row. eg: P118,R:38(somewhere is china)

But when I read the handbook,I find that the orbit number is only the ‘‘R***’’.As I show above, marked in red rectangle . Is the the Sentinel-2A orbit number ? Or I forgot some details ?

Thank you !

Hi Yang,

The ‘R’ is for Relative; the Relative Orbit (in the range (001-143) is the number of the Orbit within a complete Cycle. The actual Orbit number (or the Absolute Orbit number - i.e. the number of the Orbit since launch) can be found in the Granule filename, located in the GRANULE folder within the product.

I hope this helps
