Answer: 1.communication satellite 2.navigational satellite 3.weather satellite 4.millitary satellite 5.scientific satellite 6.satellite launches. It composed of 6 satellites...........i hope.....my answer can help you.....
How satellite communication is different from communication relay?
For communication satellites the range is much higher than that of communication relay. Communication Satellite can cover up to several thousands of kilometers. For communication relay, the uplink and the downlink frequency is the same. But for communication satellites the uplink and the downlink frequencies are different in order to avoid interference.

What has the author George Clifford Hartley written?
George Clifford Hartley has written: 'Techniques of pulse-code modulation in communication networks'
Which modulation is used in amps?
Amplitude modulation (AM) is commonly used in analog amplifiers, especially in radio broadcasting. However, in modern communication systems, techniques like frequency modulation (FM) and phase modulation (PM) are also employed, particularly in digital amplifiers. The choice of modulation depends on the application, desired signal quality, and noise resilience.
What are the three modulation techniques used for digital television transmission?
Three different modulating techniques are emploed to provide digital television (i.e. satellite, cable, UHF ) and these are known as DQPSK, QAM and COFDM. Each technique is a variation of phase modulation. QAM also takes advantage of amplitude as well as phase changes.
What are the modulation techniques for video signals?
The modulation techniques for video signals include the utilization of the amplitude modulation technique. The amplitude of the carrier wave is made proportional to the video signal voltage. It also utilizes frequency modulation technique.
What does modulation refer to?
Modulation refers to the process of varying a signal's properties, such as amplitude, frequency, or phase, to encode information for transmission over a medium. It is commonly used in telecommunications to enable efficient data transfer and enhance signal quality. By modulating a carrier wave, information can be conveyed across different channels while minimizing interference and maximizing bandwidth utilization. Modulation techniques are essential in applications like radio broadcasting, satellite communication, and digital data transmission.
What is modulation and how is it used in communication systems Can you provide two examples of how modulation is utilized in modern technology?
Modulation is the process of varying a carrier signal's properties, such as amplitude, frequency, or phase, to encode information for transmission. In communication systems, modulation is used to efficiently transmit data over long distances by converting the information into a form that can be carried by the carrier signal. Two examples of how modulation is utilized in modern technology are: In Wi-Fi technology, modulation techniques like Quadrature Amplitude Modulation (QAM) are used to encode digital data into radio waves for wireless communication between devices. In digital television broadcasting, modulation methods such as Vestigial Sideband Modulation (VSB) are employed to transmit audio and video signals over the airwaves for high-quality TV reception.
The amount of frequency shift during modulation is called?
Frequency shift keying in digital communication and Frequency modulation in analog communication..........
Need of modulation in communication?
Need for modulation: 1. Length of the antenna for a transmitter is inversly proportional to the frequency of the signal to be transmitted. So we try shift the frequency of the singal for the transmission to higher frequencies. 2. Every transmission of signal in a bandwidth is assigned with a particular frequency which is attained by modulating the signal with the carrier frequency. Different modulation techniques are implemented according to the requirements and compatibilities

Is current is a signal?
Yes, current can be considered a signal in certain contexts, particularly in electronics and telecommunications. It refers to the flow of electric charge, which can carry information through modulation techniques such as amplitude modulation (AM) or frequency modulation (FM). In these cases, variations in current can represent data, enabling communication and control in various systems.
What is modulation in data communication?
Data modulation is a method of Electronic packing of data. In Data communication data is transmitted through a process which is called "Data Modulation".
