| 摘 要： | 在机载多传感器数据融合系统中导航误差是影响目标定位精度的主要误差源.针对此应用背景提出了惯性导航误差模型,其能很好地满足实际惯性导航系统中存在的误差传播特性.仿真分析表明,与以前系统中仅利用高斯白噪声作为导航误差的情形相比,该方法更具有实际意义,对数据融合的分析更具有说服力.

| Abstract: | Navigation error is the primary error origin of target positioning precision in Airborne Multi- sensor data fusion system. The model and simulation method of INS based on airborne data fusion system which is consist with the simplified error model of practical inertial navigation system is proposed. The navigation data of airborne multi-sensor data fusion system are produced by way of ideal track data plus gauss white noise. Comparing with the present other methods, the proposed model used for producing the inertial navigation error has much higher confidence level in the analysis of airborne data fusion precision. |
