三边测量和定位是在各种网络和应用中使用的重要位置估计技术。通过简化得到的方程组可以简化为更简单的线性方程组，可以求解该线性方程组以得到封闭形式的解析解。利用这种解决方案的技术，我们开发了一种新的和独特的分析模型的定位误差所造成的三边测量。该分析模型可用于分析所有应用中的定位误差，其中包括物联网、无线传感器网络和全球导航卫星系统，从而提高定位的可靠性和质量。作为一个例子，我们使用的分析模型来证实的事实，定位误差是一个函数的拓扑结构的参考位置，除了距离估计误差。通过仿真实验验证了分析模型的正确性。
Trilateration and multilateration are important location estimation techniques used in a diverse range of networks and applications. The system of equations yielded by multilateration can be reduced to simpler linear equations which can be solved to arrive at a closed form analytic solution. Exploiting this solution technique, we develop a novel and unique analytical model for the localization error resulting from trilateration. The analytical model can be used for the analysis of the localization error in all applications wherever multilateration is used for position estimation including internet of things, wireless sensor networks and global navigation satellite system thereby increasing reliability and quality of localization. As an example, we use the analytical model to corroborate the fact that localization error is a function of topology of reference positions in addition to distance estimation errors. The analytical model is verified using simulation experiments.
