Abstract :
The sub-ionospheric VLF signal strength varies significantly with place and time. The solar eclipse and regular solar terminator motion effects on the Global Ionospheric Weather (GIW) and hence the VLF propagation. It has been simulated considering wave guide mode theory of VLF radio signal propagation along various transmitter to receiver great circular paths. Using Long Wave Propagation Capability code, the mode theoretical results are obtained. To estimate the ionospheric weather changes by VLF technique during a total solar eclipse, a three dimensional model of disk obscuration & its ionospheric consequences has been constructed.
