Abstract

We offer a hybrid model of phase of trans-ionospheric GNSS signals. The model allows the simulation of all components of trans-ionospheric signal phase variations due to effects of the background ionosphere, travelling ionospheric disturbances of different scales, Fresnel ionospheric irregularities, and measurement noise in a receiver. The proposed model combines actual TEC and analytical representation of GNSS signal frequency variations. The model was tested when pre-assessing the standard procedures for processing phase measurements and calculating ionospheric indices such as TEC, ROTI, σϕ, d2fi and fd. The application of the model demonstrates its efficiency and usability in selecting the optimal types and parameters of procedures to filter and de-trend phase measurements and to calculate the ionospheric scintillation indices based on high temporal resolution GNSS data. As a potential practical application, the proposed model is a promising tool for training artificial intelligence algorithms to provide effective automatic detection of specific classes of ionospheric disturbances or ionospheric responses to certain types of impacts.

一种载波相位混合模型，用于调整程序以处理高时间分辨率电离层无线电探测测量

我们提供了一个跨电离层GNSS信号相位的混合模型。该模型允许模拟由于背景电离层、不同尺度的行进电离层扰动、菲涅耳电离层不规则性和接收机测量噪声的影响而引起的跨电离层信号相位变化的所有分量。该模型结合了实际TEC和GNSS信号频率变化的解析表示。在预评估处理相位测量和计算电离层指数（如TEC、ROTI、σ φ、d2fi和fd）的标准程序时，对该模型进行了测试。应用结果表明，该模型在选择相位测量滤波和去趋势过程的最佳类型和参数，以及基于高时间分辨率GNSS数据计算电离层闪烁指数方面具有较好的有效性和可用性。作为潜在的实际应用，所提出的模型是一个很有前途的工具，用于训练人工智能算法，以提供有效的自动检测特定类别的电离层干扰或电离层对某些类型影响的响应。

期刊介绍： The COSPAR publication Advances in Space Research (ASR) is an open journal covering all areas of space research including: space studies of the Earth''s surface, meteorology, climate, the Earth-Moon system, planets and small bodies of the solar system, upper atmospheres, ionospheres and magnetospheres of the Earth and planets including reference atmospheres, space plasmas in the solar system, astrophysics from space, materials sciences in space, fundamental physics in space, space debris, space weather, Earth observations of space phenomena, etc. NB: Please note that manuscripts related to life sciences as related to space are no more accepted for submission to Advances in Space Research. Such manuscripts should now be submitted to the new COSPAR Journal Life Sciences in Space Research (LSSR). All submissions are reviewed by two scientists in the field. COSPAR is an interdisciplinary scientific organization concerned with the progress of space research on an international scale. Operating under the rules of ICSU, COSPAR ignores political considerations and considers all questions solely from the scientific viewpoint.
