Orbital data problem

Hello,I am using ASAR data. I use the SNAP software to open the WSM data, and there is a track data in the header file. I don’t know what coordinates X, Y, Z are inside, please guide me. Thank you!

Could you please specify your aim with the data? The metadata contain information on the position of the satellite. But this is managed by SNAP internally in most of the modules.

Hello,I want to calculate the relative azimuth (yaw angle) of the satellite. I need to use the coordinates of the satellite. What is the coordinate of the orbit data in SNAP? What is the coordinate system? Is the geocentric fixed coordinate system or the geocentric inertial coordinate system?
