| Abstract: | Chang'e-1 deliberately crashed into the moon's surface,on the March 3,2009 at 08:13 UTC,thus ending its mission. Using USB and VLBI tracking data,the location of the impact crater is determined by statistical orbit determination. The tracking data before last control is processed to investigate data quality,and the ranging system error and solar radiation pressure coefficient are also determined for the use of the last arc. Our results show that the impact occurred at 52.255oE/1.657oS,and its lunar elevatio... |
