We've added a new GROUP on the GP Current Data page at celestrak.org/NORAD/elemen... for synthetic aperture radar satellites. If you notice anything missing, please let me know. The same is true for any list: amateur radio, cubesat, weather, Earth resources, SatNOGS. We can't do it without you!

We have been tracking issues with the 18 SDS GP data for several days now. The data for more than half the catalog is now over 1 day old. That significantly affects the accuracy of those objects, especially the ones in LEO. You can see the latest status at: celestrak.org/NORAD/elemen....
