In plain English

What it measures. Files describing the NISAR satellite's flight path, that is, where the spacecraft is as it orbits.

How it's made. Generated for the NASA-ISRO NISAR mission as a utility describing the spacecraft's trajectory.

How & where you'd use it. A technical helper used in processing NISAR's radar data accurately, not a product for general use.
