Abstract

: Precise navigation, as a method for guiding vehicles from one point to another, is an important subject these days especially in navigation of aircraft. Global navigation satellite systems (GNSSs) are capable tools for such a purpose. Any intentional or unintentional interference in satellite signals may cause risks of deadly accidents. Therefore, it is tremendously important to control airports or harbors and locate any existing radio frequency interference device. This localization can be done based on measuring time of arrival (TOA), angle of arrival (AOA), or time difference of arrival (TDOA) of signals from the device to sensors or receivers at some basepoints. In this article, a method is proposed based on these arrivals for optimizing the configuration created by these basepoints from a large grid of points covering a control area. Furthermore, a simulation test was performed to verify the theory, and after that a control network was designed and optimized for the international Landvetter Airport of Sweden. Our simulation studies show that when the AOA is used, our optimization is more robust with respect to the control grid resolution. In addition, optimization based on the TDOA improves the coverage over the control area with a significant reduction of error of control points, but because of the special geometric shape of the Landvetter Airport, such an optimization was not successful.

信号干扰装置定位中基点配置的优化

：精确导航作为一种将车辆从一个点引导到另一个点的方法，是当今的一个重要课题，尤其是在飞机导航中。全球导航卫星系统（GNSS）是实现这一目的的有力工具。对卫星信号的任何有意或无意干扰都可能导致致命事故的风险。因此，控制机场或港口并定位任何现有的射频干扰设备是非常重要的。这种定位可以基于在一些基点处从设备到传感器或接收器的信号的到达时间（TOA）、到达角（AOA）或到达时间差（TDOA）的测量来完成。在本文中，提出了一种基于这些到达的方法，用于优化由覆盖控制区域的大网格点中的这些基点创建的配置。此外，还进行了仿真试验验证了这一理论，并对瑞典兰德维特国际机场的控制网络进行了设计和优化。我们的仿真研究表明，当使用AOA时，我们的优化在控制网格分辨率方面更具鲁棒性。此外，基于时差的优化提高了控制区域的覆盖率，显著降低了控制点的误差，但由于陆地护卫舰机场的特殊几何形状，这样的优化并不成功。DOI:10.1061/（ASCE）SU.1943-5428.0000416。这项工作是根据知识共享署名4.0国际许可证的条款提供的，https://creativecommons.org/licenses/by/4.0/.
