【摘要】 高精度卫星轨道是提高卫星应用水平的基础,卫星精密定轨方法主要基于卫星轨道动力学理论,通过跟踪卫星轨迹的测轨技术,将几何和动力学信息进行融合。地震电磁卫星拟采用星载GPS和综合轨道求解方法进行精密定轨,并辅之以人卫激光测距,其定轨的精度可达厘米级。更多还原

【Abstract】 To improve the application of satellite, the precise orbit parameter is the basis, which mainly depends on the satellite orbit dynamics and technique tracking satellite to combine the geometrical and dynamical information. With GPS-based satellite tracking observation,comprehensive orbit solution and Satellite Laser Ranging(SLR),the precision of earthquake electromagnetism satellite orbiting can reach to centimeter grade.更多还原
