Abstract To study the detecting errors of lunar elevation of Laser Altimeter, the on-orbit measurement data obtained from Laser Altimeter of Chinese Chang’e-1 is investigated. Firstly, the elevation data from latitude 60°to 90°in the South and North Polar Regions are divided into different small sectors along latitude directions. Secondly, a series of process were developed in each small sector, such as searching the elevation repeated data, rejecting the gross error (pseudo elevation) data, calculating the residual error and standard deviation and presenting the results. Finally, the processing results from the South and North Polar Regions were compared and analyzed. And it turned out that the average standard deviation of the South Polar Regions which latitude is between 60°and 90° is larger than that of the North Polar Region. The research results will provide the scientific basis for further analyzing error sources of Laser Altimeter. And they also offer theory guidance and reference data to the design of effective loading which exploring satellites carry.
