摘要
分布式转发平台的位置误差,是诱偏暨导航一体化系统中导航误差的重要因素。在分别推导了由转发平台位置误差和信号时延造成的系统定位误差的基础上,提出了转发平台的位置误差补偿算法。该算法是通过将转发平台的位置误差等效到所转发信号的时延上,在接收机解算中对时延信息进行补偿,从而提高系统的导航定位精度。通过理论推导和仿真验证了此算法的有效性。
The error of the transmitters＇ position was the primary influence in navigation of the GPS AMBN （area-mapping deceiving unites battlefield navigation integrative system）. The navigation error which was brought by the fiat error and the time delay was studied firstly. Then, the compensatory algorithm of fiat error was proposed. The error of the transmitters＇ position was equivalent to the time-delay error of the transmitters＇ signal. The receiver could compensate the time delay in the navigation calculation. The precision of navigation could heighten by this way. In the end, the validity of the Algorithmic was validated by the simulate results.
