Objectives
Within this project, GPS measurements at high sampling rates (50 Hz) have been recorded in both high and low latitude regions. A data base has been constituted. These data have been used to derive the scintillation characteristics and improve scintillation models.
The locations of the different receivers are indicated on the figure below. For some of them, we had an internet connection. For the others, the data recorded was sent by regular mail. Two kinds of receivers have been used. GSV receivers include an algorithm which extracts the scintillation parameters, namely the intensity and phase indexes every minute. An equivalent algorithm has been developed to extract these parameters for the Javad receivers.
Additional points to this study include the analysis of data from IGS network, the generation of time series corresponding to scintillation samples in order allowing receiver testing and the development of one forecast model allowing obtaining scintillations maps.
Challenges
Within this project, GPS measurements at high sampling rates (up to 50 Hz) have been recorded in both high and low latitude regions. A data base has been constituted. These data have been used to derive the scintillation characteristics and improve scintillation models.
Additional points to this study include the analysis of data from IGS network, the generation of time series corresponding to scintillation samples in order allowing receiver testing and the development of one forecast model.
