On the plot the Spacecraft visibility relative to the groundbased station is shown as a function of the Moscow time.
Date is shown along the X-axis, the Moscow time (MT=UT + 3 hours) - along the Y-axis.
The Spacecraft visibility relative to the corresponding groundbased station is labelled with the 1-hour step.
The Spacecraft passing through the selected simulative geophysical regions are shown as well by the corresponding symbols.
