Abstract To study the detecting uncertainty of lunar elevation of Laser Altimeter on Chang’E-1 satellite, lunar surface on-orbit elevation measurement data was investigated. Firstly, the elevation measurement data with laser altimeter were selected from lunar mare flat terrain region. Then, the main uncertainty sources were analyzed and the corresponding mathematical model was established. Finally, the uncertainty evaluation was researched based on Monte Carlo method (MCM), in addition, the evaluation results of several lunar mare elevation detection were given and compared with the results of guide to the uncertainty in measurement (GUM). The results show that the evaluation results of MCM are essentially in agreement with the results of GUM. The processing results can be contrast with the results of other lunar detection, in order to have more and updated discoveries of the moon and space environment.

Key words： metrology elevation of lunar surface Chang’E-1 satellite laser altimeter lunar mare measurement errors uncertainty
