A set of simulation system is developed on LabVIEW platform for the beacon pointing and acquisition process of the satellite laser communication. This system simulates the satellite orbit and attitude dynamics, establishes the binary pointing relationship and simulates the initial alignment of the turntable with two degrees of freedom. The beacon laser is driven to do the helical scanning according to the size of the uncertain region. The beam angle and the field of the detector determine the simulation acquisition point so as to acquire it. And then equivalent sinusoidal disturbances with Gaussian noise 1°/s maximum speed and 1°/s2 maximum acceleration are used to finish the dynamical acquisition experiment. Finally, the pointing and acquisition simulation of the dynamic binary laser communication between a geostationary earth orbit (GEO) and a low earth orbit (LEO) is accomplished, and the simulation model of the laser communication process based on the virtual instrument is also constructed, which estabishes the foundation for the tracking system simulation and beaconless acquisition simulation.
