Analysis of Ionospheric Monitoring System (IMS) Total Electron Content (TEC) data and equatorial phase-scintillation data. Scientific report No. 1
Many military systems used for communications, command and control, navigation, tracking, and surveillance depend on reliable and relatively noise-free transmission of radiowave signals through the earth`s ionosphere. This report documents the results of the first year of a three-year investigation of various facets of this problem. Two study areas are reported on: (1) an investigation of methods for using signals from Global Positioning System (GPS) satellites to measure ionospheric Total Electron Content (TEC), and (2) a study of the shape and behavior of the phase-scintillation power-density spectrum (PDS) over a scale-size range of 1Os to 1OOs of kilometers. The phase PDS study found that the slope of the phase PDS at these scale sizes is steeper than those found in earlier studies at shorter scales.
