On application of Q-guidance method for satellite launch systems

摘要

The main purpose of the paper is to present sophisticated means to implement Q-guidance scheme in satellite injection missions. Optimality and simplicity of Q-guidance approach makes it appropriate for practical settings of a wide range of launch systems. Calculation of required velocity as a fundamental and inherent concept of Q-guidance implementation for orbital injection missions has been proposed through two methods based on two different concepts; single impulse and bi-impulse orbital transfer. Implementation and comparison of the schemes on a test problem are invoked. Stochastic simulation and performance analysis in presence of uncertainties are also investigated. Accuracy and robustness of the algorithms are discussed accordingly.
