Satellite launcher pointing for orbit injection with uncontrolled solid-propellant last stage

An orbit injection method is suggested for satellite launchers with an uncontrolled last stage, addressing both orbit plane geometry and inclination issues. An impulsive approach is used to model the transfer to an orbit, with last stage burning synchronized through its thrust acceleration profile. The method is also supported by strong in-flight identification of suborbital trajectory parameters, and feasibility preevaluation within fault conditions and requirements priorities. An iterative procedure determines, to the chosen precision, the parameters values needed to provide the best feasible orbit injection. Simulation tests results are used to demonstrate the good performance and reliability of the method.
