Abstract:

Satellite ephemeris information is a key parameter for rapid positioning of aircraft after takeoff, and the number of loaded ephemerides and the loading strategy of the ground control system play a crucial role in flight position calculation. To ensure that the aircraft completes the ground debugging work to the maximum extent and simultaneously achieve rapid positioning of the airborne receiver, this paper adopted a modular decoupling design method and developed a ground satellite loading strategy meeting the requirements of rapid positioning. While ensuring the output of auxiliary positioning information, it also met the function of high-precision timing and positioning on the ground. This paper emphatically introduced the satellite ephemeris calculation method based on Newton iteration and the multi-dimensional ephemeris loading strategy in the full sky domain, which met the high-precision positioning requirements of receiving equipment and simultaneously provided a guarantee for rapid positioning of lower-level products. The test results indicate that the rapid convergence algorithm of navigation message based on Newton iteration ensures rapid convergence of ephemeris data within a limited time; the multi-dimensional satellite calculation strategy in the full sky domain steadily promotes the improvement of receiver positioning performance; the receiver can steadily improve satellite calculation speed and accuracy by preloading a certain amount of high-quality satellite information, meeting rapid positioning requirements of equipment under positioning systems at different time periods.

Key words: ephemeris, loading strategy, Newton iteration, modularization, high precision

摘要:

卫星星历信息是飞行器起飞后快速定位的关键参量,地面控制系统装订星历数量和装订策略对飞行位置解算起着至关重要的作用。为了最大限度保证飞行器完成地面调试工作同时实现机载接收机的快速定位,采用模块化解耦设计方式,研制出一种满足快速定位需求的地面卫星装订策略。在保证辅助定位信息输出的同时满足地面高精度授时定位的功能。着重介绍了基于牛顿迭代的卫星星历解算方法及全星域下多维度星历装订策略,满足接收设备高精度定位需求同时为下级产品快速定位提供保障。试验结果表明:基于牛顿迭代的导航电文快速收敛算法确保星历数据在有限时间内快速收敛,全星域下多维度解星策略为接收机定位性能提升产生稳步促进效用,接收机可以通过预装一定数量的优质卫星信息稳步提升为卫星解算速度和精度,满足不同时段定位系统下设备快速定位需求。
