With more than 40 funded Lunar missions due to launch in the next 10 years and the number of earth orbiting satellite increasing rapidly, the need for precise and reliable autonomous navigation has never been greater. Current methods of navigation at high altitudes are costly and have limited accuracy, while scientific and crewed missions have increasing more stringent navigation and timing requirements. Initial studies by NGI and others are showing the potential for GNSS to be used at Lunar altitudes, in many cases outperforming ground based tracking techniques. The addition of navigation sources in Lunar orbit are showing vast improvements in navigation performance enabling many novel scientific missions and autonomous rendezvous and landing. NGI have developed a simulation software for the analysis of spacecraft navigation performance with GNSS and other systems. This research will build on the initial studies performed at NGI to define different augmentation systems and the potential for additional sensors to improve performance and enable autonomous navigation for Lunar orbits.

随着未来10年内将有40多个月球探测任务得到资助，地球轨道卫星的数量也在迅速增加，对精确可靠的自主导航的需求从未像现在这样强烈。目前的高海拔导航方法成本高，精度有限，而科学和载人飞行任务对导航和定时的要求越来越严格。NGI和其他机构的初步研究表明，全球导航卫星系统有可能用于月球高度，在许多情况下，其性能优于地面跟踪技术。在月球轨道上增加导航源显示出导航性能的巨大改进，使许多新的科学任务和自主交会和着陆成为可能。NGI开发了一个仿真软件，用于分析使用GNSS和其他系统的航天器导航性能。这项研究将建立在NGI进行的初步研究的基础上，以确定不同的增强系统和额外传感器的潜力，以提高性能并实现月球轨道的自主导航。
