To determine the minimum number of geostationary communication satellites required to cover the entire Earth, we can follow these steps: ### Step 1: Understand the Geostationary Orbit A geostationary satellite orbits the Earth at a specific altitude where it appears to be stationary relative to a point on the Earth's surface. The radius of orbit (R) from the center of the Earth is approximately 42,400 km, which includes the Earth's radius (about 6,400 km) and the height (h) above the Earth's surface (approximately 36,000 km). ### Step 2: Calculate the Area Covered by One Satellite The area covered by one geostationary satellite can be calculated using the formula for the area of a circle: \[ A = \pi (R + h)^2 \] ...

Perhaps, the most commonly used mode of communication involves use of free space as a communication channel between transmitter and receiver. The various possible modes of using of free space have been described below Ground wave communication : This mode is used for low frequency as at high frequency, losses become large. This is useful for distance of the order of 1 km. Space wave communication: The signals are transmitted directly from transmitter to receiver. There is no limit to upper frequency, but its range is limited to few hundred kilometers. The range depends on the height of transmitting antenna Sky wave communication : The signals are sent towards sky They are reflected back towards earth by ionosphere. Its range can be above 500 km. But, very high frequencies (above 10 MHz) are not reflected back. Satellite communication: The signals that cannot be reflected back by ionosphere are reflected back by satellite. Moon is a passive satellite of earth. The frequency range allotted to FM radio broadcast is 88 MHz to 108 MHz. Which of the following communication channels can be used for its transmission? A. Sky wave communication only B. Space wave communication only C. Satellite communication only D. Either space wave communication or satellite communication
