【摘要】：為提高多星座GNSS衛(wèi)星軌道模型的可視化效率,從衛(wèi)星橢圓軌道的近似,統(tǒng)一同一星座衛(wèi)星軌道半長軸長度,基于K-means算法對升交點赤經(jīng)數(shù)據(jù)進行聚類劃分與重新賦值這3個方面對模型進行了簡化,并進行了仿真計算.仿真結(jié)果表明,該方法的采用顯著減少了需要顯示的軌道數(shù)量,減少了完成模型渲染所需的時間,提高了每秒顯示幀數(shù).多星座GNSS衛(wèi)星軌道模型的可視化效率得到明顯提高.
[Abstract]:In order to improve the visualization efficiency of the multi-constellation GNSS satellite orbit model, from the approximation of the satellite elliptical orbit, the half-axis length of the satellite orbit of the same constellation is unified. Based on the K-means algorithm, the model is simplified and simulated in three aspects: clustering, dividing and revaluing the red meridian data of ascending intersection point. Simulation results show that the proposed method can significantly reduce the number of tracks needed to be displayed, reduce the time required to complete model rendering, and increase the number of frames per second. The visualization efficiency of multi-constellation GNSS satellite orbit model is improved obviously.
