NISAR Radar Pointing
land NASA ASF Level 1A active XML
In plain English

What it measures. Engineering files that record where the NISAR radar antenna is pointed, available at different accuracy levels from quick forecasts to precise after-the-fact values.

How it's made. Produced as part of the NASA-ISRO NISAR mission to document the radar's pointing.

How & where you'd use it. A behind-the-scenes input used to correctly process and geolocate NISAR radar imagery, not a product general users work with directly.

Official description

The NASA-ISRO Synthetic Aperture Radar (NISAR) Radar Pointing collection contains the radar pointing files for the NISAR mission. The collection includes multiple accuracy levels defined by the product type where FRP=Forecast Radar Pointing, NRP=Near real-time Radar Pointing, and PRP=Precise Radar Pointing.
