R = (h/2) + c^2/(8h)
= (115/2) + 1605^2/(8 X 115)
= 2857.52717 pixels
The radius of the Earth is 6378.1km.
1 pixel = 6378.1km/2857.52717 = 2.23203477km
2.23203477km X 734 = 1638.31352km
Lastly for the timeframe.
T = 1638.31352km/1.02s
= 1606189.73/340.29
= Mach 4720.06151
Final Results
Gridman's Fixer Beam = Mach 4720.062
