Orbit generator |
Once a trajectory has been generated, it can be used by different models. This means that, in the context of a given project, it is not necessary to generate coordinates for each model separately.
Warning: The SPENVIS orbit generator (i.e. SAPRE) only provides the user with the best guess for a particular orbit. SAPRE should not be used for a real mission planning.
Finally, note that the Modified Julian Date (MJD) used in SPENVIS is defined as the number of days from 1st January 1950 00:00 UT.
