Precise Orbit of Sentinel-1

Dear all,

I processed the S1 images using SNAP software for the earthquake application. I checked the forum and found that the Sentinel-1 has a precise orbit. On the other hand, I think I applied the precise orbit processing for my study area. Now, I need to work with a modeling software which has a parameter named “rampFlag” to remove the orbital error. I would like to be sure that I don’t need to be active this parameter in the modeling process.

I do really appreciate if you let me know your comment about my opinion.

Best regards,
Sayyed
