It is an application intended to help artificial satellite mission designers in their search for repeated ground-track, frozen orbits in the case of planetary satellite.

Access to the application.

 
 

 

  1. Previous versions of these models were installed at the Centre National D'Etudes Spatiales (CNES).
  2. The ZERGOF code used is a translation to ANSI C by J. F. San Juan although the original code was implemented in FORTRAN by M. Lara.
