Approximate Solution of Sensitivity Matrix of Required Velocity Using Piecewise Linear Gravity Assumption

Author

Abstract

In this paper, an approximate solution of sensitivity matrix of required velocity with final velocity constraint is derived using a piecewise linear gravity assumption. The total flight time is also fixed for the problem. Simulation results show the accuracy of the method. Increasing the midway points for linearization, increases the accuracy of the solution, which this, in turn, depends on the total flight time.
