Radar satellites locate clouds and measure heights while orbiting earth above the atmosphere, and ground stations hold instruments that measure air pressure, temperature, dew point, etc.
magnitude and distance betwean the stations, but not right left deviation, assuming the ground is the same.
A technique called frequency reuse allows satellites to communicate with a number of ground stations using the same frequency, by transmitting in narrow beams pointed toward each of the stations. Beam widths can be adjusted to cover areas - footprints - as large as the entire United States or as small as a state like Maryland. Two stations far enough apart can receive different messages transmitted on the same frequency. Satellite antennas have been designed to transmit several beams in different directions, using the same reflector.
they are powered by ground control on earth
If you have a dish for your TV service then you're getting a television feed via a satellite feed. Likewise, digital imagery is sent from earth orbiting or deep-space satellites to ground stations for processing. For example, GeoEye and DigitalGlobe have a constellation of satellites that takes pictures of earth that are processed to display on Google Earth and Google Maps.
Remote sensing is the examination or the gathering of information about a place from a distance. Such examination can occur with devices (e.g. - cameras) based on the ground, and/or sensors or cameras based on ships, aircraft, satellites, or other spacecraft.

The information from radar and satellites is obtained remotely from above the Earth's surface, providing a broader perspective of the area being observed. This data is collected through sensors and instruments on satellites or radar systems, allowing for continuous monitoring over large areas. On the other hand, information from ground stations is collected locally from specific points on the ground, offering more detailed and precise data but limited to a smaller area of coverage.
Satellites and ground stations.
Satellites send images and data back to Earth using radio waves. The satellite collects the information with its sensors and cameras, processes it, and then transmits it to ground stations on Earth. The ground stations receive the data and images, often through large antennas that are pointed at the satellite as it passes overhead.
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.
They are not affected by conditions on the ground. Ground-based stations could be destroyed by severe weather (such as tornadoes or hurricanes). Satellites don't get affected by Earth's weather. Of course - satellites are at risk of meteor strike and solar radiation - but there's less chance of them being damaged.
Satellites do not typically report their positions as they orbit the Earth. They are constantly tracked by ground stations to ensure their proper functioning and monitor their location, but they do not "report" this information as they move.
Space probes use radio waves to send information back to Earth. They are equipped with radio antennas that transmit the data collected by the instruments on board to communication satellites or directly to ground stations. The transmitted signals are received and processed by ground stations to analyze the data collected by the space probe.
The International Space Station communicates with Earth primarily through antennas and satellites. Data is transmitted using radio waves to ground stations located around the world. These ground stations then relay the information to mission control centers for analysis and communication with the astronauts.
Satellites collect and send raw data to ground stations for computers to process and use complex computer models to predict future weather patterns.
