Modeling VLF signal amplitudes over Indian sub-continent during the total solar eclipse

We present the simulation results incorporating the effect of solar eclipse (22nd July, 2009) on VLF signals for West-East propagation path with respect to Indian Navy transmitter (VTX) assuming a Gaussian variation of the ionospheric reflection height as a function of propagation distance along the transmitter-receiver great circle path. We use both the wave-hop and the Long Wave Propagation Capability (LWPC) codes. Using wave-hop theory we found that a reasonable matching between the observed and simulated results are achieved.
