Ionosphere study



Ionospheric Scintillations
Figure 1. Scintillation induced perturbations on the signal power levels (top plot) and carrier phase range measurements, obtained from the CSM for GPS L1.

 


prompt correlator outputs
Figure 2. In-phase (I) and quadra-phase (Q) prompt correlator outputs shown for GPS L1 comparing the absence (top) and presence of scintillation. The plots refer to the first 5 seconds of 20th minute of a particular simulation.
