Question: (a) An artificial satellite revolves around the earth at a height of 1000 km. The radius of the earth is 6.38 x 10 3 km,

(a) An artificial satellite revolves around the earth at a height of 1000 km. The radius of the earth is 6.38 x 10³ km, mass of the earth = 6 x 1024kg, universal constant of gravitation = 6.67 x 10-11 Nm² kg-2.

What should be its orbital velocity (units: m/sec) so that it revolves round the earth?

(b) What is geometric distortion in remote sensing imagery? Briefly explain the five main factors affecting the image geometry.
