Satellite telescopes gather a huge amount of data. There are really two kinds of data. "Housekeeping data" is information about the satellite and its health and safety. It tells you where the satellite thinks it is pointing, what its temperature is, which parts are working, and similar status information. This housekeeping data is used by the ground crew to make sure everything is working properly.In addition, the instruments on board also have their data, "Science data". This is the fun stuff -- the images, spectra, count rates, and other measurements of the celestial object you want to study. Most of the data that you transmit to the ground will be this science data. Scientists also use the housekeeping data to evaluate how well the instruments were functioning during the collection of their science data.Data is stored onboard the satellite and sent down to earth in batches, every orbit or every day or as often as possible. Sometimes, data can be sent in realtime -- as the instruments make their observations, they instantly beam the results back to Earth.
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.
A satellite
A satellite Video PID (VPID) is a unique identifier that is used to assign a specific video stream within a satellite transmission. It helps receivers to identify and decode the video data accurately from the satellite signal.
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.
A satellite takes a picture by capturing light reflecting off Earth's surface with its onboard camera(s). The satellite's imaging system converts the light into digital data that is transmitted back to Earth for processing and analysis.
Satellite systems can be used to transmit audio data
Satellite systems can be used to transmit video data
Electrical or magnetic storms interfere with some of the data-collection methods of a satellite.
Satellite dish is used to receive the data colleted by the satellite and to give commands to it.
A satellite communication simply bounces a radio or data wave to another satellite or a receiver on earth. Satellites all act as giant relays for data transmissions.
