- Terrain Referenced Navigation, referred to as TRN, is the one of the multi-sensor integrated navigation
systems. And it has recently gained the interest as a backup system of conventional navigation methods due to
widespread availabilities. In TRN, the terrain height measurement is correlated with terrain database to correct the
position error. TRN is a powerful navigation method in the moon where does not have position fixing methods like
GNSS. The terrain height information is used to achieve the navigation performance for precise lunar landing approach.
The terrain height information of TRN is obtained using high performance ranging sensor LiDAR(Light Detection And
Ranging). LiDAR is well developed showing its potential for TRN. Especially, LiDAR can make the height information
which has high accuracy, resolution and update rate. This paper explains the component of TRN based on LiDAR. And
we discuss the configuration of precise terrain referenced approach based on LiDAR height measurement for landing on
