WebJun 24, 2024 · In real-time PPP, when GNSS satellites are retracked by the receiver, the reliability of measurements variances of the first several epochs estimated by the EAS-ROTI model will be affected since the ROTI is calculated by using a sliding window for each 5 min interval, that is, 10 epochs for 30 s sampling interval data, as seen in Equation . For ... WebThe GNSS-based ROTI (rate of TEC index) is one of the most widely used indices to monitor the occurrence and intensity of ionospheric irregularities. In this paper, we examined the long-term performance of the ROTI in terms of finding the climatological characteristics of TEC fluctuations. We considered the different scale temporal signatures ...
