I have similar concerns. When I visited the http://www.astrodynamicstandards.org/ site, the banner says that "The Public Astrodynamic Algorithm Distribution Site is no longer available." While the documentation for the APIs appears to be included with the distribution package, it's now a bit more closed than it used to be. The site stopped direct distribution sometime between February and April of 2018, so it's been like this for a while. I use https://web.archive.org/ to figure this out. There are other Federal projects which publish tools via Github, but I suppose there's some constructive sensitivity to well-understood algorithms being published now. I disagree with the current tack which Space-Track seems to have taken. John On 11/11/2020 21:18, Chris Kuethe via Seesat-l wrote: > This is their binary build for x86 and x86_64 windows and Linux.
