Hello
Does satellite signal behave like radio signal,radio signal go far doing night time but day time radio signal need more power.
So does satellite signal stronger night time than day time?

A terrestrial radio signal is enclosed inside the ionosphere, and will propagate distances depending on the Reflection and / or bending of the radio signals due to the ionosphere behaviour.
A satellite radio signal traverses the ionosphere part for only a fraction of its travel from / to the satellite and the ionosphere, in general, does not affect its strength.
Of course, every radio transmission is affected during a Solar Flare burst.

 

No.

The radio signals that fade in the day......are of a different frequency than the sat signals.

The earth's atmosphere has a bandpass.....or a filtering effect on radio signals. This effect is controlled by ionization of the atmosphere. The ionization is controlled by sunlight and space weather.

So for some frequencies.....time of day controls distance. But there are certain frequencies...that are effected very little......and can be used for 24/7 for communications.

An amateur radio handbook can explain this signal propagation to you.
