Abstract

The satellite-earth laser communication APT (acquisition, pointing and tracking) system's accuracy demand is described and a method of modeling and simulation for error analysis is introduced at the beginning of this paper. Then simulation architecture is given with the satellite APT system function description. Models such as atmosphere turbulence, satellite platform vibration, motor & Gimbals etc are analyzed and established. Integrated simulations are done by assembling all the models and controllers as a real terminal. How the factors such as sampling rate, system delay influence system accuracy and how much the factors such as satellite platform vibration, atmosphere turbulence etc. contribute to the system error are summarized clearly in tables. Some error analyses are done and a good choice of coarse and fine sensor sampling rate is recommended combined with the system accuracy demand in the preliminary design.
