This program creates a satellite macro model for the estimation of non-gravitational accelerations acting on a satellite.
Mandatory input values are the \config{satelliteName}, \config{mass}, \config{coefficientDrag} and information
about the satellite \config{surfaces}. For low Earth orbiting satellites, like GRACE for instance, a good guess
for the drag coefficient could be 2.3. Apart from that, it is latter on possible to estimate a more precise variable drag coefficient
(e.g. \configClass{miscAccelerations:atmosphericDrag}{miscAccelerationsType:atmosphericDrag}), which will override this initial guess.
Concerning the satellite surfaces an external file must be imported which must contain information about each single
satellite plate in terms of plate \config{area}, the associated plate normal and re-radiation properties
(reflexion, diffusion and absorption) properties in the visible and IR part. Examplarily, a description of
the macro model for GRACE can be found under:
\url{https://podaac-tools.jpl.nasa.gov/drive/files/allData/grace/docs/ProdSpecDoc_v4.6.pdf}
Additionally, it is possible to add further information like antennaThrust, solar panel, temporal mass changes and
massInstrument using the modules option.
