The ISS maneuvers from time to time to keep its orbit intact and/or to avoid space junk. So its keps change more frequently and more significantly than other birds. Using a source for keps that’s updated very frequently will help you track it better. At the suggestion of others, I shifted to using nasabare.txt on SatPC32, but there may be other sources that are equally as good if not better. I tracked ISS today for the SSTV event and had no problems.

Dear Group:

 

I’ve noticed that the live tracking of the ISS is located differently on different websites and Ham Radio Deluxe.

I fired up SATPC32 and it seems correct with the ESA Webpage.

Live tracking on the AMSAT Webpage page is following my HRD which seems 3 or 4 minutes behind the ESA Webpage.

I have updated all my keps which align with the AMSAT live tracking location.

This morning while trying to download SSTV from ISS I was unable to track it properly.

I had a huge signal before it even reached the horizon.

 

 

 

Any suggestions or remedy.
