What is first communication satellite?
The first communication satellite was Echo NASA
Where you can get the frequency of bharathtv?
here is the satellite & frequency details of Bhaarath TV ================================================================ SATELLITE: Insat 2E at 83°E DOWNLINK FREQ: 4042 POLARISATION : Vertical SYMBOL RATE: 8000 FEC: 7/8
What is the importance of the Morse code?
A: Today it has not much value except for die hard amateurs radio operator. At one time it was extensively used because the range of communication at low frequency transmission dot line it could circumvent the globe Nowadays with the satellite circling the globe it has become a curiosity. The generation of the code was done with breaking a switch to cause the transmitter to output a wave more popular was dedicated wires whereas the useful transmission
What is fsk in communication?
fsk is nothing but frequency shift keying which is used in low speed modems.....
How does communication take place?
In cellphones, communications takes place via radio waves to a satellite, or via an underground cable network.
What is the down link frequency to earth?
The downlink frequency to Earth, in the context of communication satellites or spacecraft, refers to the frequency at which data is transmitted from the satellite to Earth. The specific frequency used can vary depending on the satellite system and the communication protocol being employed. Generally, downlink frequencies for satellite communication are in the microwave frequency range, typically between 1 to 50 GHz. The choice of downlink frequency is influenced by factors such as transmission range, atmospheric absorption, and regulatory requirements.
For satellite communication the frequency should be less than critical frequency?
For satllite communication the frequency should not be less than the critical frequency because in satellite communicaton high frequency is needed which is reflected by satellite but not by the ionosphere.
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 is the lower limit of frequency for satellite communication?
20 GHz
What is the telephone frequency range used for communication?
The telephone frequency range used for communication typically falls between 300 Hz to 3.4 kHz.
What is frequency of a satellite wave?
I never heard of a "satellite wave". If you mean the radio waves used by satellites for communication - well, like all radio waves used for such purposes, there is probably a large range of waves they can use.
Why is the up link frequency higher than the down link frequency in satellite communication?
The uplink frequency is higher than the downlink frequency in satellite communication because higher frequencies can carry more information and are less affected by interference and noise. This setup allows for efficient communication between ground stations and satellites, ensuring a reliable transmission of data.
What are modulation techniques in satellite communication?
frequency modulation, preferably.
What is up converter in satellite communication?
Every information sent and received through satellite communication has to have an address to enable the communication process of signal delivery and reception. This naming of the signal is made in the form of a specific frequency. For example each TV channel operates on a unique frequency of it's own. When that frequency is called (tuned technically) out of a spectrum in that band, the chosen frequency gets selected. Since satellite transponders operate at very high frequency, modulation of the signal on to the carrier is difficult. Hence modulation is carried out at a much lower frequency. Such modulated signal is raised to the required frequency( name or address as stated above) that supports the satellite band and the transponder. The equipment used to elevate the frequency of the low frequency carrier (known as Intermediate Frequency) to the satellite transponder frequency is UP CONVERTER C.K.Vasudeva Bangalore
What is the correct terms when describing the frequency range of 3 kHz to 300 GHz?
Electromagnetic Frequency (EMF) & Radio Frequency (RF)
How many watts does an EPIRB transmit?
An EPIRB typically transmits at a power of 5-6 watts in the 406 MHz frequency range for satellite distress communication.
Define downlink frequency?
In the sense of a mobile communication: Downlink frequency is that used by a base station to communicate with the Mobile. In satellite communication also the same theory exists downlink is the return path.
