Abstract

The complementary radio navigation system based on the Very Low Frequency signals produced by lightning is an alternative to today's Global Navigation Satellite Systems. The system operates on different principles and uses different radio frequency bands. The signals have higher availability in problematic places. The analyses based on the historical data of Word Wide Lightning Location Network demonstrated the good availability of the service, sufficient number of lightning strokes and good geometry calculated for a 10-second time window for positioning based on the Time of Arrival principle. The geometry was evaluated with the help of the Geometric Dilution of Precision coefficient. The Geometric Dilution of Precision median for the reception of the lightning signal from a range of 10,000 km moves around one except at the southern polar regions and the probability of the service availability exceeds 80%.

研究闪电发出的无线电信号是否适用于远距离导航
基于闪电产生的甚低频信号的补充无线电导航系统是当今全球导航卫星系统的替代系统。该系统基于不同的原理运行,使用不同的无线电频段。在有问题的地方,信号的可用性更高。根据 Word Wide Lightning Location Network 的历史数据进行的分析表明,该服务的可用性良好,有足够数量的雷击,根据到达时间原则计算的 10 秒定位时间窗口的几何形状良好。几何精度是通过几何精度稀释系数来评估的。除南极地区外,从 10,000 公里范围内接收闪电信号的几何稀释精度中值在 1 左右移动,服务可用性概率超过 80%。
