Analysis on the Relationship between Burst Errors and Tracking Control Frequency in Satellite-to-Ground Laser Communications

Abstract:

In this paper, burst errors in uplink communication due to lags of the tracking system control in Satellite to Ground optical link was analyzed in detail. In order to make sure how about these bursts in uplink communication are affected by control frequency can, system model of the satellite terminal was founded, parameters of a satellite in sun synchronous Low Earth Orbit and detectors were set to initialize the simulations. The zenith angle of the link was set in the range of [0°, 70°]. The simulation results showed that the bursts due to lags of the tracking system control were different for communication links, but the bursts can be avoided by raising the control frequency to a certain level if it accessible.
