Typical Fault Analysis and Solution of Polar Orbit Meteorological Satellite Receiving System of 4.5 Meters
This paper introduces the composition and function of FY-3 meteorological satellite data receiving system with 4.5 m antenna in polar orbit meteorological satellite receiving system,and analyzes in detail the polarization problem,low AGC level and frame loss of signal with automatic tracking function.Through a series of tests,the cause of the fault is accurately located,and a solution is proposed for the fault,which effectively improves the receiving quality of satellite cloud image,significantly reduces the number of lost frames of data packets,and improves the service level.
