Description: This dissertation provides experimental observations and analyses that associate low-latitude transionospheric signal scintillation with transequatorial VHF radio propagation and errors in transionospheric geopositioning. The experiment observed equatorial-region ionospheric total electron content (TEC) derived from Global Positioning System (GPS) signals using receivers on Oahu, Hawaii, Christmas Island, and Rarotonga, Cook Islands. The experiment simultaneously measured VHF transequatorial propagation of VHF television signals from Hawaii to Rarotonga Analysis shows that a moving second moment of vertical-equivalent TEC strongly correlates to each VHF transequatorial radio propagation event From experimental observation analysis, the author develops models for prediction of TEP and nine-space distribution of low-latitude transionospheric scintillation. The author also develops equations that show the potential errors in nine, frequency, and angle used in geopositioning solutions. These three parameters are potentially correctable using these techniques.
