Low-Thrust Optimal Orbit Raising with Plane Change

I. Shafieenejad; Alireza Novinzadeh

Volume 6, Issue 2 , June 2009, , Pages 79-85

  A new guidance scheme for the problem of Low-thrust transfer between inclined orbits is developed within the framework of optimal control theory. The objective of the guidance scheme is to provide the appropriate thrust steering program that will transfer the vehicle from an inclined low earth orbits ...  Read More
