GPS Positioning Accuracy in Different Modes with Active Forcing on the Ionosphere from the Sura High-Power HF Radiation

© 2020, Springer Science+Business Media, LLC, part of Springer Nature. 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

GPS positioning accuracy during the 2016 September and 2010 August campaigns at the SURA heater

We have conducted ionosphere heating experiments using HF radiation of SURA facility in August of 2010 and in September of 2016. We analyzed GPS positioning accuracy during the experiments. Positioning errors were estimated for 14 GPS receivers located at various distance, from just at the facility up to more than 1000 km from the facility. Data show that there were no noticeable positioning errors for both precise point positioning (PPP) and standard single-frequency modes
