| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | For centimeter level satellite navigation service, it is important to estimate the amount of ionospheric delay that causes positioning errors. In conventional ionospheric delay estimation techniques, when propagating ionospheric disturbances (TID) occur, which cause fine ionospheric delay variations on the order of tens of kilometers, the accuracy of ionospheric delay estimation is degraded. This results in a decrease in positioning accuracy. To address this issue, we propose a TID detection technique based on the Time-Space Fourier transform, which utilizes the plane-wave structure of TID. Through experiments using GNSS data of actual TID, we confirmed that it is possible to detect TID and estimate the spatial distribution of ionospheric delay. |
