[sci.space] Equations of artificial satellites' motions wanted

john@ritcsh.UUCP (John Bisaillon) (04/18/89)

    I am planning to write software that will predict common and useful
information about the position and motion of an artificial satellite.
I want to be able to just input the time and the current orbital elements of
a particular satellite.  I need to know the equations of motion that
use orbital elements and a given time to predict the three dimensional
position of the satellite.  Extremely high accuracy in terms of calculations
is not needed.  Any infomormation on existing equivalent public domain
software is also appreciated.  Thanks in advance.
