导航操作需要对设计轨迹进行细化，以获得用于飞行路径控制和科学操作的高精度轨迹。初步弹道设计通常涉及边界值问题的近似解，这些近似解为使命设计提供足够的精度，但对于飞行操作不够精确。最终的精确轨迹是通过用目标和优化算法驱动高精度轨迹模型来获得的，这些算法产生最终的高精度解。初步的轨迹设计提供了一个初始的猜测，开始瞄准算法。根据经验，有时可以省略初步设计，直接通过瞄准获得弹道设计。
Navigation operations require the refinement of the design trajectory to obtain a high-precision trajectory for flight path control and science operations. The preliminary trajectory design often involves approximate solutions of boundary value problems that provide sufficient accuracy for mission design but are not accurate enough for flight operations. The final precision trajectory is obtained by driving a high-precision trajectory model with targeting and optimization algorithms that yield the final high-precision solution. The preliminary trajectory design provides an initial guess for starting the targeting algorithm. With experience, the preliminary design may sometimes be omitted and the trajectory design obtained directly by targeting.
