| Summary: | Korea’s lunar exploration project includes the launching of an orbiter, a lander (including a rover), and an experimental
orbiter (referred to as a lunar pathfinder). Laser altimeters have played an important scientific role in lunar, planetary, and
asteroid exploration missions since their first use in 1971 onboard the Apollo 15 mission to the Moon. In this study, a laser
altimeter was proposed as a scientific instrument for the Korean lunar orbiter, which will be launched by 2020, to study
the global topography of the surface of the Moon and its gravitational field and to support other payloads such as a terrain
mapping camera or spectral imager. This study presents the baseline design and performance model for the proposed
laser altimeter. Additionally, the study discusses the expected performance based on numerical simulation results. The
simulation results indicate that the design of system parameters satisfies performance requirements with respect to
detection probability and range error even under unfavorable conditions. |
