Is this how weather and communication satellites work?

  1. Feb 4, 2010 #1
    Hello guys, first post ;p

    I am currently doing an info search for physics at school about weather and communication satellites. I'm not 100% sure if they're right because I've surfed the web and either get too broad answers or one that makes no sense lol

    At the moment, my understanding of how comm satellites work is a ground station transmits electromagnetic waves which carry an audio or video message and is received by the comm satellite with its convexo-concave shaped dish. The message is amplified and is retransmitted to another ground station on Earth or another comm satellite.

    I'm a bit more uncertain about weather satellites, but here's my interpretation. The sensors on the weather satellite scan the levels of infrared radiation and visible light and transmit the information to a weather station for them to piece together the information and produce an image.

    Please let me know if these are correct/incorrect, it would be much appreciated! =)

    Thanks!
