How do I get those spacetrack graphs? Do I have to be a .mil person? Is there a DIY space tracking service out there?

  > How do I get those spacetrack graphs? NORAD's Space Track service makes the raw two-line elements available, but over the recent decade they have tightened usage and distribution restrictions. By the letter of the terms of service, one who downloads the data may not disclose the raw data or anything derived from it. https://www.space-track.org/documentation#/user_agree https://www.space-track.org/documentation#/user_agree As a result, amateur satellite tracking groups have to 'disregard' Space Track data and determine orbital elements through their own observations.

    An exception exists for TLEs redistributed by CelesTrak.com. Sources: http://celestrak.com/NORAD/elements/notice.asp#Update16 http://celestrak.com/NORAD/elements/notice.asp#Update16 and personal correspondence with the operator. (Note also that the Space Track terms do not prohibit individuals from requesting accounts for personal use.)

    Aren't the works of the federal government, by letter of the law, public domain? Wouldn't this negate their terms of service?
