美国国家宇航局的小卫星技术倡议(SSTI),在高性能、低成本的航天器项目中占有首屈一指的地位。通过美国技术投资的杠杆作用并尽量减少用户管理的失误,从而大大降低成本,缩短研制周期,同时使航天器性能达到当代技术水平,这些正是美国国家宇航局的要求。利用最先进的敏感器、处理机和结构技术,使得路易斯SSTI小卫星制导、导航及控制分系统大大提高了最轻型卫星计划的指向精度。大幅度减少的用户操作失误,广泛继承以前计划的分系统,灵活应用固有的高可靠性设计和测试经验,这些因素的结合,使得该分系统在原有的预算下,不到两年就完成了。同其它高质量的轻型卫星相比,路易斯SSTI小卫星的制导、导航及控制分系统的性能更高,完成时间更短,生产成本更低,而且拥有同样的甚至更高的品质。
NASA’s Small Satellite Technology Initiative (SSTI) is the number one high-performance, low-cost spacecraft project. By leveraging the leverage of U.S. technology investments and minimizing user-management errors, costs are significantly reduced and development cycles are shortened, while enabling spacecraft performance to reach contemporary technological levels is exactly what NASA calls the United States. Leveraging state-of-the-art sensors, processors and fabric technologies, the LSIS Satellites Guidance, Navigation and Control Subsystem greatly improves the pointing accuracy of the lightest satellite programs. Dramatic reductions in user misoperations, widespread inheritance of previously planned subsystems, and flexible application of inherent high-reliability design and test experience combined with these factors allowed the subsystems to be completed in less than two years under the original budget . Compared with other high-quality light satellites, the guidance, navigation and control subsystem of the Louis SSTI Small Satellite has higher performance, shorter completion time, lower production cost and the same or even higher quality.
