|Abstract:||Predicting and bounding the ionospheric rates of change that affect Global Navigation Satellite System (GNSS) signals is of interest for filtering and processing GNSS signals. Although dual frequency measurements may be used to directly estimate and remove the effects of ionospheric variation, there are situations where continuous measurements from more than one frequency may be limited. Further, there may be more advantageous ways to combine information from multiple frequencies, particularly when the ionospheric rates are small. This paper presents an analysis of the potential error of this ionospheric rate estimate under both nominal and disturbed ionospheric conditions using historical data, including previously identified extreme ionospheric events.|
