Spacecraft-tracking software uses “Keps” or Keplerian elements (also known as “orbital” or “tracking” elements) to pinpoint the location of a spacecraft. Keps provide the software with a spacecraft’s orbital track, which the computer uses to calculate its location. Using a tracking program tells an observer when a spacecraft will appear above his or her horizon.
