Transferring a signal from a ground station to a satellite is called?

Uplinking.


What is the transmission from a satellite to an earth-based station?

The transmission from a satellite to an earth-based station is typically done using radio frequency signals. The satellite sends data to the ground station through a process called downlinking. The ground station receives the signals, processes the data, and distributes it to its intended destination.


Why in satellite communication power at radio station is higher than at satellite?

Because of economics. On the ground you an afford to use a big transmitter and a big antenna, while on the satellite both have to be smaller. Therefore most of the power and the gain happens at the ground station.


What is the value of transmitting power in link budget anlysis of satellite?

That's going to depend on the particular ground-station equipment for the uplink, and the transponder power for the downlink. If you don't know these, then you need to get them before you can begin the analysis of the satellite link budget, and if you don't understand that they can be different for every link, then you really ought to trust the analysis to another engineer.


What is passive satellite?

A satellite that simply reflects light or radio waves transmitted from one ground station to another without any amplification or retransmission.


Uplinking and downlinking in TV broadcasting?

In up-link the portion of a communications link used for the transmission of signals from an earth terminal to a satellite platform.. a down link is the link from a satellite to a ground station..


What is the purpose of launching of aryabhata satellite?

To indigenously design and fabricate a space-worthy satellite system and evaluate its perfromance in orbit. To evolve the methodology of conducting a series of complex operations on the satellite in its orbital phase. To set up ground-based receiving, transmitting and tracking systems. To establish infrastructure for the fabrication of spacecraft systems.


What sends data to a satellite?

A transmitter sends data to a satellite, typically using radio waves. The data is transmitted from a ground station, a vehicle, or a mobile device to the satellite, which then relays the information to other satellites or back down to Earth.


What is uplink frequency?

Uplink frequency is a frequency that goes from the ground to the satellite. Downlink frequency goes from the satellite to the ground.


How do satellites transfer information to television?

satellites must transmit all their information to the earth down .satellites transmit information gathered by their sensors during each contact with the ground station. They contact the station using a large dish antennae which is situated on earth, at the site of the ground station. During the contacts between the satellite and ground station the satellites usually transmit information about the state of its various subsystems abd its position in space.


Difference bitween active and passive satellite?

In passive satellite system the ground transmitting system power at the reflector. The receiving ground system received a function of the power that has been intercepted by the reflector. In active satellite received the function of the energy band toward it by the ground transmitter system and the received power is active amplitude by active electronic means.


What is the Round Trip time of a RF signal for GEO satellites?

the speed of light = 299792458 m / sGEO (Geostationary Earth Orbit) = 35863000 m above the Earth's surfaceround trip time = 2*(35863000)/299792458 =0.239 sthe time needed for an RF signal to reach a GEO satellite and gets retransmitted back to a ground station on earth is approximately 240 milliseconds(assuming zero signal propagation/processing time in the satellite and equatorial ground station location with the same longitude as the satellite slot)
