Optimal Injection into Near Synchronous Orbit by Three Apogee Motor Burns Accounting for Operational Constraints and Execution Errors.
Abstract
The procedures for maneuvering the German telecommunications satellite TV-Sat from its elliptical transfer orbit to GEO are described and illustrated with diagrams. The optimal-injection problem is defined, taking the characteristics of the thrusters, the transfer orbit, and the spacecraft into account and providing for error correction; optimization goals include minimal fuel consumption and ease of computation. The resulting nonlinear optimization problem with equality and inequality constraints is solved by applying a nonlinear optimization algorithm, and a nominal strategy involving three burnings of the apogee motor is selected. The algorithm is also implemented in a software package for use at the German Space Operations Center to recompute optimum maneuvers when errors occur. The results of simulations demonstrating the effectiveness of the method are presented in tables and graphs.
