Measurement of the Characteristics of TIDs Using Small and Regional Networks of GPS Receivers during the Campaign of 17–30 July of 2008

Figure 6

Cross-correlation functions (top panels) and TECP curves (lower frames) for GPS satellite 13. The left frames show the CCFs for TECP signals from Huancayo and Chupaca. The right panels correspond to Huancayo and Sicaya. The cross-correlation functions are plotted using a color scale that varies between 0.9 and 1.0. The black line that crosses near the middle corresponds to the maximum and it is taken as the time delay (𝑇_𝐵−𝐴 or 𝑇_𝐵−𝐶).
