Research On Target Acquisition Model And Algorithm Of Satellite Under Complicated Constraints

With the development of science and technology,people on the use of various resources on earth has been maximized,the earth's various resources have been a serious shortage.With the deepening of people's research on outer space,how to make full use of this piece of public resources has become the focus of attention.Satellite as the most widely used space equipment,it is into people's vision for its excellent performance.There are many different kinds of satellite and different types of satellite application are also different.A complete satellite observation system includes:satellite,orbit,sensor,attitude,mode and so on.By setting the orbital simulation start time and end time to control the track length,we set the track six parameters to control the orbit position.The sensor is divided into CCD sensor and SAR sensor,the sensor payload controls the range of ground observation and image quality.The attitude is mainly by setting the maximum side angle and pitch angle to adjust the satellite's dynamic observation range.The mode provides the operating mode and load current for subsequent energy calculations.In this paper,we study the satellites along the task orbit for earth observation target acquisition path and the task sequence generated along the path observation process and the resulting energy consumption.Firstly,we construct the model of satellite earth observation,and then the target is visually accessed.In the process of access,the actual complex constraints such as lateral constraint,camera resolution constraint,solar height angle constraint and sensor width are added.We use side place constrains on visual target incompatible goals set classification.For one dimensional target acquisition(considering side swing angle),we use the greedy algorithm to analyze the visual target in order to acquire the one-dimensional path data.In 2d target acquisition(considering side swing angle and pitching angle),we assembled the incompatible goals as input,and then visual segment analysis,using the vector rotation angle analysis,we get the 2d target acquisition data path.In the two kinds of target acquisition path,we use the path data to arrange the task sequence.Then we carry out energy calculation,first of all,we analyze the satellite solar panels data and solar light data,and then analyze the satellite windsurfing shelter,build satellite windsurfing model.We use this model to analyze the charge and discharge of the satellite array and the charge and discharge of the supply array,and calculate the charge and discharge of the satellite battery.Finally,we combine the task sequence data of the above path and the relationship between the operating mode and the load current in the model to calculate the energy data generated by the satellite along the path to the ground observation target.
