Visual Simulation Analysis of Satellites Based on Ellipsoidal Conformal Phased Array
With the rapid development of China's space industry,satellites in orbit has increased dramatically,and it is difficult for limited spaceflight measurement and control resources to meet growing demands for measurement and control,based on the geo-desic dome phased array antenna(GDPAA)technology and existing mathematical structure of ground measurement and control sta-tions,a semi-ellipsoidal conformal phased array ground measurement and control station model is designed to meet actual engineering needs;the satellite tool kit(STK)and Matlab joint simulation is used to collect the data with the satellite two-line orbital element(TLE)as the target library,and the data conversion is realized through the earth coordinate system and sub-array line-of-sight coordi-nate system,which investigates the visibility relationship with the ground station site and active satellites in China;Simulation results show that the latitude and longitude are positively correlated with the visibility of satellites to accumulate the scientific data for nation-al ground station measurement and control stations,it provides a data foundation and application support for the maximizing utilization of subsequent phased-array antennas.
