ALOS-2 PALSAR2 data orbit state vector

Microwave Toolbox
#1

I am using snap software for PALSAR 2 data. Thinking of orbit correction using the Apply Orbit File in the radar tool. But in the processing parameter, under the Orbit State Vectors we do not have any such option.How do i correct the orbital errors using SNAP only.

#2

ALOS data does not need the application of external orbit files. This is already defined in the ordering process. You either select

  • most accurate and available (only if you immediately need the data)
  • high precision orbit information (this is the one you order, it takes a bit longer, but the orbit state vectors are alredy included in the delivered product)
