There are a few iterations of this, I&#x27;m personally partial to <a href="https:&#x2F;&#x2F;www.satcat.com&#x2F;globe" rel="nofollow">https:&#x2F;&#x2F;www.satcat.com&#x2F;globe</a> bc of all the other data available on site

Nice concept! I only find it unintuitive to navigate, with button panel of always truncated buttons looking strange, quasi-permanent (requires action or stays there forever) and plenty error messages that I am using it wrong (&#x27;select something first!&#x27;), overly eager tooltips everywhere, with amusement centric but impractical zoomed animation on click that is not obvious how to reverse. It must be somewhere, the whole thing looks rich in functions, but I lost interest in the tiring entertainment centric approach before finding it.

What are all those Unknown JSC Vimpel objects in that one well-defined orbit between LEO and geostationary?

Neat! It&#x27;s very cool to see what appears to be the &#x27;hoop&#x27; formed by all the geosync satellites. Yet then there appears to be a &#x27;cylinder&#x27; that contains the hoop whose axis is slightly off the hoop&#x27;s access. Any idea what that represents? By maintaining the same distance from Earth as the geosyncs, they would seem to be synchronous with a particular longitude, but would rise up &amp; down latitude above &amp; below the equator with every revolution (i.e. onr full cycle per day).

I never expected there to be so many satellites orbiting Earth. It feels like we&#x27;ve cluttered space with all these objects.

Awesome!<p>I noticed that there is another much-used orbit apart from the round, earth-centered Geostationary Orbit, which is smaller, more elliptical, off-axis and tilted.<p>It may be the Molniya Orbit [0] which is &quot;is a type of satellite orbit designed to provide communications and remote sensing coverage over high latitudes [...] The name comes from the Molniya satellites, a series of Soviet&#x2F;Russian civilian and military communications satellites which have used this type of orbit since the mid-1960s.&quot;<p>Can anyone confirm this?<p>It appears to be full of JSC Vimpel satellites, which is &quot;a Russian defense industry leader&quot; [1], but from randomly clicking on the objects many are just debris.<p>[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Molniya_orbit" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Molniya_orbit</a><p>[1] <a href="https:&#x2F;&#x2F;macvympel.ru&#x2F;en&#x2F;about&#x2F;" rel="nofollow">https:&#x2F;&#x2F;macvympel.ru&#x2F;en&#x2F;about&#x2F;</a>

Would be awesome to see the source for this tool! Also, I&#x27;ve always been curious how you get applications like this to be performant at higher resolutions without using GPUs or other graphics tricks.

Very cool. Appreciate the comments for the mesh functions in the source code...I&#x27;ve played around with photogrammetry but never took the time to appreciate how the 3D polygon logic worked at a low level (AliceVision).<p>And the UI is impressive but somewhat overwhelming. Could use a UI tool to help better manage the pitch\yaw\roll of the globe or individual vehicles\sensors (unless one already exists and I just missed it).

A user interface suggestion: I tried using the &#x27;Find Satellite&#x27; option and manually scrolling through all the options in the drop down menu was a little tedious. Maybe allow a filter by typing the first couple of letters?<p>Also, what are the US GPS satellites listed under? I saw Beidou, GLONASS, and Galileo but I couldn&#x27;t find the GPS satellites.

Once you understand all the gray points are debris it makes more sense (header &gt; layer icon)

Impressed how many of them are already there. Also interesting: <a href="https:&#x2F;&#x2F;science.nasa.gov&#x2F;eyes&#x2F;" rel="nofollow">https:&#x2F;&#x2F;science.nasa.gov&#x2F;eyes&#x2F;</a>

If you scroll down on the option, you can launch missile attacks and see its trajectory.

This is so amazing! Just a few fixes in the UX and it would be even better than satvis.

There is a feature to launch ICMBs from Russia at Washington DC?
