One of suggested ground stations for ASTROD1 mission is Yunnan Observatory 1.2mTelescope laser ranging system. In this paper we present a talk about some necessary technique for the ASTROD I mission laser ranging, include pulse and CW laser ranging. The main parts of this talk are: Introduction Key Requirements of Ground LR Station for ASTROD I Telescope Pointing and Pointing Ahead Day-Time Laser Ranging Technique Optical Layout of LR for the ASTROD I Mission
