The localization principle of bistatic sonar is given and the gdop ( geometry dilution of precision ) which used in bistatic radar for describing the localization error has been cited in bistatic sonar 在对双基地声呐定位原理和定位误差分析的基础上，提出了用定位精度的几何解释( gdop )来表征双基地声呐定位误差的方法。
Lonm tuning range is achieved in the experiments . 2 . the influence of the positioning errors on tuning range in external - cavity diode laser system is analyzed in detail for the first time as my knowledge （ 2 ）首次系统分析了外腔半导体激光器无跳模调谐结构的定位误差对无跳模调谐范围的影响，并据此设计了一套1
Experiments are desinged to prove the precision of the system . the experimental results demonstrate that the position precision is improved apparently , and the positional error of the system reduces from 10 % to 1 . 5 % 对系统的定位能力进行了实验,实验结果表明,工作台的定位精度明显提高,系统定位误差由10 %减小至1 . 5 % 。
It leads to position error . to reduce the error , many integration methods have been suggested . map matching is an useful approach to correct the error , as the reliable road maps are readily available 值得注意的是受到s / a政策的影响, gps噪声不是高斯白噪声,因此用kalman滤波技术估计的位置不再是最优的,它导致了定位误差。
