The global navigation satellite system accuracy and the possibility to actively affect it is quite a relevant problem. Based on two experimental campaigns (2010 and 2016), we analyzed the GPS positioning accuracy with forcing from the Sura high-power HF radiation. Analysis of the positioning error variations for 14 stations at different distances from the heater (directly near the latter and more than a thousand kilometers away from it) showed the absence of significant effects both in the precise point positioning (PPP) mode and in a standard iterative single-frequency positioning mode that is most frequently used.

Sura 高功率 HF 辐射对电离层的主动强迫在不同模式下的 GPS 定位精度

全球导航卫星系统的精度和对其产生积极影响的可能性是一个相当相关的问题。基于两个实验活动（2010 年和 2016 年），我们分析了来自 Sura 高功率 HF 辐射的强迫的 GPS 定位精度。对距离加热器不同距离的 14 个站点的定位误差变化（直接靠近后者和距其一千多公里）的分析表明，在精确点定位 (PPP) 模式和标准模式下都没有显着影响。最常用的迭代单频定位模式。
