Optimal Impulsive Orbital Transfer - SNOPT version

MATLAB script for the solution of the one and two impulse orbit transfer between two Earth orbits.

PDF document and MATLAB script called oota_snopt.m that can be used to determine optimum one and two impulse orbital transfers between non-coplanar circular and elliptical orbits. The method is general and the initial and final orbits need not be coapsidal.

The algorithm is based on the orbit transfer and rendezvous work of Gary McCue, Gentry Lee and David Bender, described in “Numerical Investigation of Minimum Impulse Orbital Transfer”, AIAA Journal, 3, 2328-2334 (1965); and “An Analysis of Two-Impulse Orbital Transfer”, AIAA Journal, 2, 1767-1773 (1964).

Provides 3D graphics of the initial, transfer and final orbits. Includes graphical primer vector characteristics for two-impulse transfers.

Requires platform-specific SNOPT mex and support m-files. Information about SNOPT available at scicomp.ucsd.edu/~peg/
