It has been working perfectly for about a year.&nbsp; Suddenly, about two weeks ago, we noticed the position of the ISS was &#8220;off&#8221; compared to online ISS trackers.&nbsp; We ran the problem down to the TLEs. In the scenario we had checked use the TLEs from Ansis.&nbsp; When I imported a TLE for the ISS from an outside group, the location of the ISS was correct.&nbsp;&nbsp;&lt;\/p&gt;&lt;p&gt;So my question is am I doing something incorrect, or were the TLEs for the ISS from the server stale? We are such novice users, we did not know how to figure this out, hence my post here.&nbsp; Many thanks for any advice you can give us.&nbsp;&nbsp;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;V\/R&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Geoff McHarg&lt;\/p&gt;&lt;p&gt;Air Force Academy&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-446646","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hello,We are using an STK scenario to track the location of the International Space Station for our cadets.
