why was sriharikota chosen to be the site of the rocket launch station?

Question

shar-satish dhavan space centre (sriharikota-isro)

Answer 1

Because it is located close to the equator, not being closer perhaps because of politics or building conditions further south.
Launching closer to the equator adds the spin of the earth (1000 mph at the equator) to the launch since the orbital speeds are absolute, based on gravity and distance, not relative to earth surface speed.
