There are beam-steerable phased-array antennas that can read a standard passive UHF RFID tag from about 600 feet. If you used a tag with an extra-large antenna, you could maybe get to 1,000 feet. There is no way to read a tag from a satellite. It is simply impossible.
It is like a balloon that you and I both hold together in our hands. I squeeze the balloon in Morse code, and you can feel the changes in the balloon and thus read the code. The size of this balloon is determined by the size of the loops in the reader and tag antennas, as well as the amount of energy. Generally speaking, you would not be able to read a tag from more than a few inches away, though if you had a really big loop in the reader antenna, you could get it up to a few feet.
