How does satellite imaging in the sky work?
Satillite imagining is a process where a satelitte in space is sending beams to various places on earth. these later take pictures and send it to earth

You get images from a satellite using a frequency band. The best way to access satellite images is with Google maps. However, if you want your own, you will need to have at… least $500 USD, and for larger areas up to $14,000. Look at Digital Globe for these.
about a 100 basket-ball sized satelittes fall every year.
Yes, some are visible. The Space Station is one of them.
Because they reflect sunlight at Earth as they fly over head. That is why when you see one, it starts barely able to be seen, gets brighter and then dims until you cannot see …it. It is not long reflecting light towards you any more.
Yes, the moon.
22,340 miles above the equator.
The satellites that "stay positioned" in the sky are called geostationary. The way it works is this. First, the satellite must be in orbit around the equator. Also, to stay in… orbit around the earth, an object has to have some amount of motion. It's called orbital velocity. The farther out it is, the less orbital velocity it has to have because there is less gravitational effect in those higher orbits. At some point out there, the satellite will be moving at the same speed the earth is turning, and will appear from earth to be stationary. A satellite (sometimes called a "bird") won't be moving as we see it from here. We've parked a bird in geostationary orbit.. Note: There is a slight "figure 8" motion to birds out there in those orbits. A link can be found below.
if your talking about natural satellites that would be one, the moon if you talking about real satellites i have no idea
When we look up from the earth, we are looking into the atmosphere. The atmosphere appears blue because its gases scatter solar radiation in the longest parts of the visible p…ortion of the electromagnetic spectrum. Satellites are above the atmosphere, so when they look out they see the black vacuum of space (there is nothing in space, and black is the absence of color). When they look down at the earth, they "see" through the atmosphere to the earth's surface, or to the clouds that are visible above it (if these are sensors that are detecting visible radiation). They cannot observe solar radiation being scattered. Interestingly, the sun appears white from the satellite's point of view. This is because the sun emits radiation at all visible wavelengths, and white is the combination of all colors. The sun appears yellow from the surface because again, the radiation gets scattered in the atmosphere.
I have the same question in the textbook the answer is that satellites use sensors to detect changes in the wavelength of light that is reflected from earth surface. They send… this information to computers on Earth, which process into images. Additionally Early satellite communication used radio-transmitters to transfer imagery and data to earth ground stations. Some fixed satellites today use microwave radio relay technology to communicate with the ground which is complementary to that of communication cables. Some of the commercial satellites that capture imagery of the Earth include GeoEye and DigitalGlobe , which provide the imagery used by Google Maps, Google Earth, and others.
Satellites gather data from a satellite image by using electronicdevices to collect computer data
You can see some of them if you know when and where to look. A few of them, like the International Space Station, are actually extremely bright (it can, under good conditions,… be noticeably brighter than anything in the sky other than the Sun and Moon).
You can use a compass. Once you have the dish roughly aligned left to right with the compass bearing The second step is to align the dish vertically. The correct elevation of …the dish will be dependent on the region of the world you are in.The use of a 'Sat-Finder' (B5029) will also greatly help with locating the satellite signal. The 'Sat-Finder' will give you an audible indication of signal strength as you move the dish. Can be bought on the internet.
No they don't move fast in the sky
The Sky satellite is used to beam television signal around the world and into your satellite dish. Sky themselves use the Astra 2A satellite, which is fairly newly launched.
