Q. In satellite communication 1. The frequency used lies between 5 MHz and 10 MHz 2. The uplink and downlink frequencies are different. 3. The orbit of geostationary satellite lies in the equatorial plane at an inclination of $0{^\circ}.$ In the above statements
A) Only 2 and 3 are true
B) All are true
C) Only 2 is true
D) Only 1 and 2 are true
Explanation
(a) 1. The frequency used for satellite communication is greater than 30 MHz.
2. Uplink and downlink frequencies are different to avoid interference.
3. Geostationary satellite lies in the equatorial plane of great circle. It should revolve in an orbit concentric and coplanar with the equatorial plane.
