This page is supposed to give a list of Satellite Tracking related software. A quick search on Satobs site shows that there is an extensive list dated back to the early or mid-1990th, as you can infer from the use of the archaic term such as IBM PC there. I have listed that page in the first link, but please be advised that many of the links are broken. I have removed two links from my original page and replaced them with Mike McCant’s QuickSat link. I will put ‘verifying and updating the links in Satobs Site Software page’ in my to do list.
