本论文致力于基于DWM1000模块的室内定位系统的开发、测试和在线监测的问题。已经确定，相应的系统需要校准每个测量通道。低距离室内导航系统可以使用一点校准，而长距离系统需要至少两个测量点。实验表明，由于干扰环境的测量通道可以工作在不稳定的工作模式，显着降低整个系统的准确性。它建立了这样的操作模式可以检测使用功率谱密度。可以忽略来自检测到的不稳定信道的信息，以保持室内导航系统的高精度。
The present paper is devoted to the question of development, testing, and online monitoring of indoor positioning systems based on DWM1000 modules. It has been established that the corresponding system requires calibration of each measuring channel. Low distance indoor navigation systems may use one point calibration while long distance system require at least two measurement points. Experiments show the measurement channels due to jamming environment can operate in unstable operating mode significantly reducing accuracy of the whole system. It was established that such operation mode can be detected using power spectral density. The information from the detected unstable channel can be ignored to save high accuracy of the indoor navigation system.
