Adaptive tip-tilt correction for the ASTROD mission
Abstract
Astrodynamical Space Test of Relativity using Optical Devices (ASTROD) is a newly propose space mission with deep space laser ranging. Its scientific goals are to measure the relativistic parameters with 3-6 order better sensitivity. The Mini-ASTROD is a down-scaled version of the ASTROD. The laser ranging with a distance of 1 or 2 AU between the spacecraft and the ground station will be performed. So the turbulence effects for the laser beam propagation must be considered. A new idea of the rea-time tilt correction of the laser beam on the ASTROD and the Mini-ASTROD is proposed. The technical plan for this purpose at the laser ranging system of Yunnan Observatory 1.2m telescope is introduced in this paper.
