problem1. The use of satellites in RF communication systems is very much a fact in everyday life.

(i) What are INTELSAT and INSAT satellites?

(ii) Differentiate between polar orbiting satellites and geostationary satellites.

(iii) By referring to artificial satellites orbiting the earth, state Kepler’s third law.

problem2. A satellite dish is in communication with a geostationary satellite above the earth surface.  The angle over which the satellite dish can lie is 1430.

problem3. For better communication, the dish is tilted at an angle of 100. find out the height of the satellite from the earth surface.

problem4. A satellite makes a north to south equatorial crossing at longitude 900W, completing one revolution around the earth in 102 min.  Assuming that the orbit is circular and crosses exactly over the poles, estimate the following:

(i) The number of orbits per day.

(ii) By how much will the earth rotate eastward in the 102 min?

(iii) The position of the satellite at the time 0h 10 min after the equatorial crossing.

problem5. A meteorite is a meteoroid (a solid piece of debris from such sources as asteroids or comets) originating in outer space that survives impact with the Earth's surface.  Radar systems are used to monitor this dangerous phenomenon.  In one such situation, a radar system of transceiver antenna gain of 4000, operating at a frequency of 10 GHz with a peak pulse power of 250 KW is used to track down a meteoroid. If the power pulse received at a range of 50 km is 10-11W, what is the cross-sectional area of the target meteoroid?

problem6. Using a block diagram, describe the subsystems involved of 2G system architecture.
