Path: Orbit/LowEnergyManeuver
% Calculate the nominal transfer time for a low energy transfer
The names of the moon and planet must be available in the Constant database.
Type LETPhasing for a demo.
--------------------------------------------------------------------------
Form:
[det,orbits] = LETPhasing(x0,desiredPhasing,moon,planet,et,jDate)
--------------------------------------------------------------------------
------
Inputs
------
x0 (1,1) Initial guess for a transfer time
desiredPhasing (1,1) Angle of the moon at the final time in the
Sun/Planet rotating coordinate system
moon (1,:) String name of moon
planet (1,:) String name of planet
et (1,1) Seconds after the epoch jDate at which the
transfer initiates
jDate (1,1) Julian date
-------
Outputs
-------
det (1,1) Estimated transfer time
orbits (1,1) Number of lunar orbits during transfer
