测距测量提供执行行星使命的航天器与地面站之间的精确距离。导航员、无线电科学家和行星科学家将测距应用于他们的应用，并共同提高了精度。目前，传统的测距与无线电链路相干地执行。光学测距比无线电测距有几个数量级的改进。本研究分析了月球勘测轨道飞行器在太阳系尺度上收集的单向上行链路光学测距数据。从导航角度进行分析，以确定光学测距数据的质量。由于单向数据的性质，它使用两个不同的时钟来构建一个范围，特别注意正确建模的航天器时钟，并提出了几种方法来建模的时钟。使用光学测距数据计算的轨迹都匹配公布的轨迹内公布的不确定性，并导致在一个剩余的均方根…
Ranging measurements provide precision distance between spacecraft on planetary mission and ground stations. Navigators, radio scientists, and planetary scientists use ranging for their applications and have collectively advanced the precision. Currently, conventional ranging is carried out coherently with radio links. Optical ranging promises several order of magnitude improvements over radio ranging. This study analyzes one-way uplink optical ranging data collected by the Lunar Reconnaissance Orbiter on a solar system scale. Analysis was approached from a navigation perspective to determine the quality of the optical ranging data. Because of the nature of one-way data, which use two different clocks to construct a range, special attention was paid to properly modeling the spacecraft clock, and several approaches are presented to model the clock. Trajectories computed using optical ranging data both match the published trajectory within the published uncertainty and result in a residual root mean square ...
