calculate distance from a given latitude and longitude on the earth to the special position of satellite

Question

I want to calculate distance from a given latitude and longitude on the earth to the special position of satellite. I have the lat and long and altitude of satellite. thanks in advance

Answer 1

You've got to get the distance between the points That is side "c". By using the formula: a^2+b^2=c^2; it'll happen. "a" is shortest distance; "b" mid length; "c" hypotenuse.

Now that "c" is the base; you'll have the 2 angles to work with; that is a,s,a. The angles are labeled (greek letters): alpha, opposite side "a"; beta opposite "b"; gamma "c".

So a/(sin α)=b/(sin β)=c/(sin γ).

Since you have side "c"; figure "γ' for (c/(sin γ)). That is 180-α-β=γ. You can use either side to get your distance.
