【摘要】 只有单站测速数据的情况下,传统的定轨方法难以实现初轨确定。将遗传算法应用于定轨实践,实现了无初值条件下单站测速数据初始轨道确定,并能满足收敛要求,为缓解测控资源紧张提供了重要支持。在中巴"资源一号"卫星的长期测控任务中应用,证明了本方法的有效性。更多还原

【Abstract】 It’s hard to determine the initial orbit for traditional methods with Doppler measurement data of only one TT&C station. We introduce a genetic algorithm to determine the satellite’s initial orbit. With the Doppler data of only one TT&C station, the new method can satisfy the requirement of constringency and get the initial orbit parameters. It has successfully been used to determine the initial orbit of the Chinese-Brazil resource of earth satellite for one year. Less equipment is needed than before to manage the satellites in orbit.更多还原
