This submission is a MATLAB script named demo_low_thrust that demonstrates how to model a low-thrust interplanetary trajectory from Earth to Mars. The optimal flight controls (pitch angle, yaw angle and throttle setting) for this script can be determined using a FORTRAN program named ilt_sos.
The important features of this MATLAB script are as follows:
  • maximize final spacecraft mass
  • low-thrust, patched-n-body interplanetary flyby and rendezvoustrajectory modeling
  • modified equinoctial orbital element equations of motion
  • JPL DE430 planetary ephemeris
This script reads JPL planetary ephemerides in a machine-independent binary format which are available from the SPICE web site. These *.bsp ephemeris files are IEEE-Little Endian style of binary kernel. This is the binary form native to PC/Linux, PC/Windows and MAC/Intel machines. Additional information about JPL ephemerides can be found at http://naif.jpl.nasa.gov/naif/.
The demo_low_thrust script also uses routines from the MICE software suite to read and evaluate the JPL binary ephemeris file. Platform-specific MICE mex files, support functions and the binary ephemeris files are available at naif.jpl.nasa.gov/naif/toolkit_MATLAB.html. MICE is a MATLAB implementation of the SPICE library created by JPL.
