| 摘 要： | 提出了无线电近程导航系统(RSRN S)与IN S/GPS的综合过程,探讨了RSRN S和IN S/GPS综合应用过程中的信息融合技术问题。采用GPS伪距、伪距率以及无线电近程导航定位与IN S组合,建立了卡尔曼滤波方程,设计了飞行轨迹,对相关的信息融合技术进行了初步讨论,并给出了惯性元件精度较低时组合系统的仿真输出。这种组合导航方案可以充分利用各种导航传感器的信息,有效提高导航系统的精度。 |

| Abstract: | This paper discusses the integrated process of radio short-range navigation system(RSRNS) correction and INS/GPS combination,including the technical problems of the integration of RSRNS with INS/GPS,and some measures are brought forward to them.Information fusions based on integrated navigation scheme can ful1y utilize information provided by all kinds of navigation sensor subsystems and improve the precision of the system effectively.An integrated system is established by utilizing pseudo-range,pseudo-range rate and RSRNS,constructing the Kalman filter equation,designing the flying profile,and the way with the system is integrated and the related information fusion technique is debated on.The integrated system can efficiently make use of all information of navigation sensors and effectively improve the performance of the navigation system. |
| Keywords: | information fusion federated Kalman filtering integrated navigation system |
