In satellite communication ku band in ghz refers to.

Satellite communication frequency modulation is used because satellite channel has.

In satellite communication frequency modulation is used because satellite channel has. The receiver hardware setup must be ready at any time to make it ready it s performance is to be tested continuously the frequency with which satellite data is coming is also continuously tested. An ideal power limited communication channel with additive white gaussian noise is having 4 khz band width. A satellite modem is not the only device needed to establish a communication channel.

Formerly iridium satellite llc is a publicly traded american company headquartered in mclean virginia iridium operates the iridium satellite constellation a system of 66 active satellites and 9 spares in space used for worldwide voice and data communication from hand held satellite phones and other transceiver units. A communication satellite is a repeater between. Fm used to be used for analogue tv via satellites because it had excellent noise immunity compared to am and provided a relatively good signal lock. Fm is no longer used for tv services and even in data services fm is not really used.

Other types of modulation systems use in communication satellite are quadrature systems where the modulated signals are represented in terms of two channels like i and q. Maximum bandwidth and minimum noise d. A computer the modem usually has intermediate frequency if output that is 50 200 mhz however. Satellites are usually operate at gigahertz range of frequency and the modulation signals are up converted to the transmission frequency and amplified before going on air the term modulation is also used to describe certain types of baseband processing like pulse amplitude modulation pam or pulse code modulation pcm.

Psk is using for satellite communication because psk signal can be transmitted through the non linear channel of a satellite and it depends on the proper choice of the modem filters 5. Question is in satellite communication frequency modulation is used because satellite channel has options are a small bandwidth and negligible noise b large bandwidth and severe noise c maximum bandwidth and minimum noise d high modulation index e leave your comments or download question paper. Large bandwidth and severe noise c. Amplitude modulation is used for broadcasting because.

This data has to be frame synchronized using a special hardware. What is used is phase shift keying psk and sometimes am combined with psk to form qam. The role of satellite communication in education has not been as prominent as commercial broadcasting although telemetry has been in use in education for years. Space telecommunications has also been used for many years by television networks broadcasting live news events and cross continent entertainment shows.
