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.

由于未来10年推出了40多个资助的月球任务，并且轨道卫星的数量迅速增加，因此需要精确和可靠的自主航行的需求从未如此大。当前在高海拔地区的导航方法成本高昂，准确性有限，而科学和船员任务的导航和定时要求越来越严格。 NGI和其他人的初步研究表明，在月球高度上使用GNS的潜力，在许多情况下，在许多情况下都超过了基于地面的跟踪技术。在月球轨道上增加导航源正在显示导航性能的巨大改善，从而实现了许多新颖的科学任务和自主会合和着陆。 NGI开发了一个模拟软件，用于分析使用GNSS和其他系统的航天器导航性能。这项研究将基于在NGI进行的初步研究以定义不同的增强系统，并有可能提高性能并实现月球轨道自主导航的潜力。
