How can i get the azimuth heading angle for a ERS scene? i require the actual value in degree. is there a way to find this out in snap?

Also for sentinel 1 as well, as i dont understand what the value i see in metadata means for satellite heading

thanks in advance

I am not sure what the exact definition of azimuth heading angle is but it should be closely related to the ERS orbit inclination which is 98.5 degrees.

edit: â€¦so the heading is 8.5 degrees off true north. This with the correct sign could be the azimuth heading angle I think. If it is related to the ground-track it is a bit more complicated since the rotation of the Earth has to be taken into account.

thanks a lot.i actually meant azimuth of satellite heading. sorry for that.

however, is it constant for every scene ? as i read in another thread that the satellite goes west at higher latitudes

The orbit inclination is constant over the whole orbit. You need to find the definition for â€śazimuth satellite headingâ€ť and see what the exact definition is (heading with respect to what).
