Optimization And Implementation Of Satellite Tracking Mode For Geostationary Satellite Ranging Station

With the rapid development of meteorological satellite,the number of FY-2 geostationary meteorological satellites is increasing.The Trilateration Range and Range Rate(hereafter this text will beabbreviated as TRRR)is an important part of FY-2 geostationary meteorological satellite ground application system,the main task is to complete the timing ranging.A ranging system consists of three ground stations,one main station and two auxiliary stations.At present,Four FY-2 satellites in orbit,one to be launched,A total of five sets of equipment for the main station,nine sets of equipment for the auxiliary stations in all the ground station.Since the system was first built in 2004,part of the equipment aging phenomenon has emerged,and is facing the launch plan of H star and the future may have to work until 2025,the original equipment is difficult to meet future business needs.This project is based on the original ranging system,adds the tracking mode for multiple satellites to optimize satellite tracking mode for geostationary satellite ranging station Without increasing the hardware equipments.After the software optimization,the model of tracking and ranging is changed,one system for one satellites is made to one system for multiple satellites.It will shorten the time interval for performing the ranging task,improve equipment usage frequency,maximize the utilization of new and good equipment,and allocate available equipmen Effectivly.Based on the analysis of the software and hardware environment and the interface of the original ranging station,the main work of project Optimization can be summarized as follows:1.Do feasibility analysis for Optimization of satellite tracking mode,and set up infrastructure for the tracking mode for multiple satellites by Workflow technology;2.Combine with the existing antenna tracking mode,implement scheduling and planning functions for ranging task by making a reasonable antenna tracking scheme.With the scheduling of tracking plan,the satellite can be tracked automatically.3.The man-machine interface is provided for tracking schedule and the table of satellite information;and The correspondence between the satellite and satellite orbit in can be modified in the tracking plan;4.Receive Orbital elements from SOCC,Then,analyzedhe the six elements of Kepler orbit and calculate the antenna azimuth and elevation.When the time to tracking plan,preset azimuth and elevation of antenna according to the predicted data,and implement the function of the antenna to track satellite exactly;5.When the orbital parameter analysis fails or the prediction data preset fails,the memory is used to track the satellite again;6.Have sound alarm function for abnormal signal.Give a Time-sharing alarm such as emergency situation or signal interference.
