To address routing planning of the delivery vehicle navigation in logistics, the article based on point-to-point model, improved the fundamental particle swarm optimization in the initial population, the method of population and evolutionary strategy for improvement, put forward the improved particle swarm optimization for vehicle routing point-to-point model problem of navigation in distribution, and verify the validity of the algorithm by simulation tests.

为解决物流配送车辆导航中的路径规划问题，文章以点对点模型为基础，对基本粒子群优化算法在初始种群的产生方法和种群的进化策略方面进行改进，提出适于配送车辆导航中路径规划点到点模型的改进型粒子群优化算法，并通过仿真试验验证算法的有效性。

The Japanese used suicide kamikaze pilots to direct flying bombs with deadly effect against American ships, proving the superior guiding ability of the human brain, and the Germans successfully used the V-1 flying bomb as a weapon of terror against London—a large target a short distance away that was hard to miss.

日本在那次战争中使用了自杀式的神风特攻队队员来引导自动导航导弹，对美国舰队造成了致命的打击效果，这也证明了人类头脑拥有无可逾越的引导能力；此外，德军也成功地用V-1自动导航导弹做为打击伦敦的恐怖武器——要打中近距离的一个大的目标是很难出现失误的。

With adjusting the epoch time and ephemeris data at the criteria of constraint Least-Mean-Square-Error, the geolocation accuracy can reach 2 pixels in the whole images; and it can be improved to approximately 1 pixel in the whole images and less than 1 pixel at nadir by considering the spacecraft attitude deviations moreover.

如果进行历元时刻和卫星轨道根数的约束最优调整，导航定位精度在整条轨道大范围内可提高到2个像元左右；如果再加入卫星姿态偏差的校正，导航定位精度在整条轨道大范围内可稳定提高到1个像元左右，在星下点附近小于1个像元。
