Algorithm of Ionospheric Scintillation Monitoring

With the development of the Beidou satellite navigation system, the monitoring of ionospheric scintillation combined with GPS and Beidou system has become a trend. In this paper, the design and implementation of the upper computer software for ionospheric scintillation monitoring are introduced, and the related algorithms such as ionospheric amplitude scintillation monitoring, ionospheric phase scintillation monitoring and ionospheric TEC monitoring are discussed and analyzed. The ionospheric scintillation monitoring system developed in this paper can calculate the ionospheric amplitude scintillation index and ionospheric phase scintillation index of the L1/L2 frequency point of GPS satellite and the B1/B2 frequency signal of Beidou satellite in real time. It can also calculate the ionospheric parameters such as TEC, σ_TEC, ROT and ROTI of each satellite, and can store the observed data and make the judgement and analysis of ionospheric scintillation events. Finally, the functional test results of ionospheric scintillation monitoring system are given, and discussed and analyzed.
